Welcome to CoCoRaHS in The Bahamas
Welcome to CoCoRaHS – the “Community Collaborative Rain, Hail and Snow Network” in the Bahamas. We are a group of volunteer observers, working hand-in-hand with the Bahamas Department of Meteorology, measuring precipitation in our own communities. Collectively we are able to track storms across each of the family islands. Thanks for joining the observing team. We hope this will be an educational and fun activity. Here is some information to help you get started.
LOGGING INTO THE WWW.COCORAHS.ORG WEB SITE If you filled out the application on the www.cocorahs.org web site and provided an e-mail address, an e-mail was sent directly to the address you provided. This message contained your default username and password. After typing in this information, click the "Save Login" checkbox, and you will not have to log in again from that computer. If you did not receive the message, your e-mail system may have blocked it so please check your blocked mail folder. If you forget your username or password you can have them e-mailed to you at any time by using the "Find Login Information" form at www.cocorahs.org/FindLoginInfo.aspx.
CHECKING THE ACCURACY OF YOUR STATION NAME When your station is established we locate it on maps using the address or coordinates provided in your application. Your station name is determined by your distance and direction, as-the-crow-flies, from the geographical center of the town indicated by your station name. The geographical center of the town or landmark is normally where maps place the city name. For example, the name Nassau 3.3 SE, indicates that the gauge is located 3.3 miles southeast of the approximate center of Nassau. We sometimes make mistakes so PLEASE CHECK YOUR STATION NAME. If the name does not reasonably describe your location, please email us. You can also click on the link to Google Maps in your CoCoRaHS account information to view your station location. Once you have logged into your CoCoRaHS account, the server will automatically fill in your station name on your data entry form each day. Your STATION NUMBER is based on the state and county in which you live. Each station has a unique station number that is automatically assigned. OBTAINING A 'COCORAHS 4-inch PLASTIC RAIN GAUGE' All volunteers need to use the same type of gauge (4" diameter, high capacity) so that our data are consistent and compatible. CoCoRaHS vendors who provide reduced rates for CoCoRaHS volunteers include: WeatherYourWay and additional suppliers. The gauge should cost around $33 plus shipping (shipping to the Bahamas from the US can be a bit pricey). The gauges are usually shipped out right away so you can set up your gauge in a matter of days.. In some situations, sponsors may provide approved rain gauges at little or no cost to volunteers. Please check with your volunteer coordinators to see if complimentary sponsored gauges are available in your area. The cost of a gauge should not stop you from joining.
GETTING READY TO GATHER PRECIPITATION DATA The best way to get started in CoCoRaHS is to attend a training session for new volunteers. Check with your local coordinator about dates and locations. Your local coordinator's name and e-mail address can be found in the "cc" box in the header of your welcome e-mail, or call your CoCoRaHS coordinators found at the end of this document. Visit the CoCoRaHS Bahamas page. You may also train on-line on the CoCoRaHS website. Click on "Bahamas Training" to access training material as well as view our animated training materials via our YouTube page. Additional information is contained with "Things to know about Rain, Hail and Snow" and also under "FAQ/Help". However, we recommend attending a training session if it is offered in your area because you can ask questions and enjoy the company of others interested in weather watching. If you have attended a CoCoRaHS training session or gone over the training materials on-line, and have your rain gauge in place, you can begin reporting immediately. REPORTING DAILY PRECIPITATION The most common way to report your daily precipitation totals as well as special hail and intense precipitation reports is on our website: www.cocorahs.org . To report your precipitation measurements click on "My Data". Feel free to fill in the "Observation Notes" section with any additional information that will help describe your observation and the weather you experienced. If you have an iPhone or Android based smart phone, you can report daily observations via the free CoCoRaHS observer app. The CoCoRaHS iPhone App is available at the Apple Store: https://itunes.apple.com/us/app/cocorahs-observer/id827714558?mt=8
The CoCoRaHS Android App can be downloaded via the Google Play Store: https://play.google.com/store/apps/details?id=com.appcay.cocorahs
TIME OF OBSERVATION We have selected 7:00 a.m. as the preferred time for daily observations since it is most convenient for the majority of volunteers and a time when it is less likely to be raining. For mapping precipitation and comparing data among stations, it is helpful to all measure at about the same time. If your schedule does not permit you to check your gauge at 7:00 a.m., please make sure you type in the actual time you took your observation on the data entry form. Observations made before 4:30 a.m. or after 9:30 a.m. are still appreciated, but will not appear on the daily maps. If it is raining at or near your observation time, it is important for you to report exactly when you read and emptied your gauge so we can interpret the data properly. If it is not raining, reporting the exact reading time is not critical. We realize that you may not have time to report your observations to us exactly at 7:00 a.m. The sooner you can report, the better, but report whenever you are able. You can go back at any time to report data from past weeks, months, and even years. Please make sure you enter the date of observation correctly when you enter data from the past.
REPORTING INTERVALS We greatly appreciate daily reports covering consistent 24-hour periods when possible, even when there has been no precipitation (report 0.00") or just a trace (report "T"). For many reasons, including drought monitoring, it is just as important to know that it didn't rain at your location, as well as when it did! If you are away from your gauge for a period of time, enjoy yourself and don't worry about CoCoRaHS. You may ask a friend, neighbor or co-worker to read your gauge for you. Another option is to report the total precipitation in the gauge when you get back. Little rain evaporates from the gauge as long as the funnel is left in place.
To report rainfall while you were away, use the "MULTI-DAY ACCUMULATION FORM". When you return, follow the instructions on how to enter an accumulated rainfall amount for a period of multiple days. REPORTING HAIL STORMS AND INTENSE RAINFALL If you observe hail, submit an on-line "HAIL REPORT" after each storm. This information is really helpful even if the hail is small, soft, or not comprised of many stones. If you were not at home and do not know the exact time of the storm, please submit a hail report with any observations you have, even if approximate. If you experience heavy rain or other significant weather in progress, please submit a "SIGNIFICANT WEATHERREPORT." Rainfall exceeding 0.30” - 0.50" per hour is considered heavy rain. If rainfall exceeds 1-2 inches per hour, your timely report may be extremely important as flooding conditions may be developing rapidly. All hail and significant weather reports are automatically transmitted to the Bahamas Meteorology Department in Nassau. Your information may be critical to alert forecasters of threatening weather. Currently, Bahamas CoCoRaHS is not participating in the "hail pad" portion of the program, but you are welcome to make your own hail pads or you can purchase one at weatheryour way.com. Even if you do not have a hail pad, please report hail when it is falling at your location.
REVIEWING YOUR DATA REPORTS After you begin reporting data to CoCoRaHS, please refer to the "MAPS" section on our web site for your city and island. Make sure your data are appearing, and showing up in the correct location. If not, please let us know immediately at info@cocorahs.org. When you submit your report, it may take a few minutes before it appears on the maps. Also, you can check reports by clicking on "LIST/EDIT MY REPORTS" under the "MY DATA" section, or by clicking "VIEW DATA" near the top of the page. Always make sure your data are typed correctly and entered for the correct date. If you make a mistake with a daily entry, click on the pencil to the right of the report and resubmit the corrected entry. Many may look at and use your data and these data will be archived indefinitely. All maps, both recent and historic, are posted on the CoCoRaHS web site. As you examine them, you will begin to learn along with us how precipitation patterns vary in our states. You can review all the data reports you have submitted, or you can check the rainfall totals for all stations in your area. Just experiment! DATA ERROR MESSAGES CoCoRaHS volunteers check data from all volunteers on a regular basis to spot errors. Don't be concerned if you get a message asking you to check one of your reports. We just want to make sure the data are as accurate as possible. Please make sure that your e-mail accepts messages from bahamas@cocorahs.org, noah@cocorahs.org, nolan@engr.colostate.edu, and qc@cocorahs.org. We rely on e-mail to keep you posted, so don't let your SPAM filter block us out. CARE FOR YOUR RAIN GAUGE We have found that our gauges begin to get brittle over time. With reasonable care, you should get 5-20 years of use out of the gauge. If you want your gauge to look new for a long time, wrap the outside with a thin coat of foil or other material to reflect ultraviolet radiation. Avoid putting anything inside the funnel, as that could affect the accuracy of your data. We've been told that some automotive care products applied to the outside of the gauge may add to the life of the gauge, but they may make it slippery to hold. If you want to keep your gauge clean and looking like new, put some warm water with a little gentle liquid hand soap in the tube and let it soak for a few minutes. Then twist a thin soft towel and spin it into the cylinder until it reaches the bottom. This will wipe out most of the dirt. It is not recommended to use a firm bottlebrush to clean the gauge, nor is using your automatic dishwasher (this will gradually scuff and haze the inside of the gauge). Another method is to take a newspaper, roll it to make a tight cylinder, and then rotate the paper on the inside of the tube all the way to the bottom. It will usually clean out the dirt. VOLUNTEER SAFETY Do not put your personal safety or health at risk to read your gauge. Do not wading into flood waters or being struck by lightning when reading your gauge. Remember, weather at times can be violent. Use the same precautions when reading your gauge as you would with any other outside activity.
NETWORK UPDATES & ACTIVITIES Your name will be added to our CoCoRaHS e-mail list, and periodically you will receive project updates and reminders. We try to limit our messages to about two per month. Should your e-mail address or mailing address change, please let us know so we don't lose contact with you. If you do not want to be on our e-mail list, just let us know. You will also want to make sure that our messages are not blocked by your e-mail's SPAM filter. Check our web pages for periodic updates. We use our web site to keep volunteers informed of our progress and upcoming activities. We also provide links to interesting weather and climate websites and educational resources.
COCORAHS AND SOCIAL MEDIA
Are you a social media person? If so you can follow CoCoRaHS via Facebook and Twitter. The CoCoRaHS Blog is another spot where you can find out great information about weather and climate while leaving comments and questions for discussion.
THE ORIGIN OF COCORAHS The CoCoRaHS network was created as a result of the Fort Collins, Colorado flash flood of July 28, 1997, and the storm the following evening on Pawnee Creek, near Sterling, Colorado. Both storms produced more than 12 inches of rain in a short period of time, but over very small areas. In Fort Collins, several areas within five miles of the storm center received just two inches of rain or less. The flood claimed several lives. The Colorado Climate Center was responsible for documenting those storms. It took months of work to piece together the puzzle. Without reports from private citizens with rain gauges, we would not have been able to map and study those storms. In 1998, the network gained the support of organizations that benefit from detailed local weather data. Then in 2003, a National Science Foundation Grant helped us expand beyond the Fort Collins area. This was followed by a NOAA's Environmental Literacy Program Grant in 2006 which allowed us to expand to all fifty states. In 2010 we were awarded grants from both the National Science Foundation and the NOAA Office of Education. With the help of these sponsors, as well as financial donations from other organizations and individuals, we have been able to continue to keep CoCoRaHS operational and will continue to make improvements to make the network a more fulfilling experience. For many years we have recognized a need for more detailed local weather data to document our climate patterns and water resources. CoCoRaHS is now making this a reality. In May 2016, the Bahamas joined the network. Internationally, there are thousands of citizens of all ages (from school age children to folks in their 80s and 90s) active in CoCoRaHS, providing a wealth of precipitation data not previously available!
COCORAHS AND THE FUTURE CoCoRaHS is a low-tech, low-cost but highly effective approach to a challenging problem. Precipitation is very important and highly variable. Weather stations in existing official weather observing networks are just too far apart. Automated weather stations are useful, but too expensive and not always accurate. By encouraging as many volunteer weather watchers as possible, CoCoRaHS provides local information on rain, hail, and snow that helps fill the gaps between traditional weather stations, thereby providing valuable information for forecasting, research, and education. As CoCoRaHS continues to grow across the country we realize that our volunteers are our best resource for recruiting new participants. If you know of others who may want to join CoCoRaHS, please encourage them to apply. Our hope is to have a dense network of active CoCoRaHS volunteers across all of the Islands of the Bahamas to fill in the gaps.
YOUR COCORAHS PRECIPITATION MEASUREMENTS WILL BE USED BY MANY PROFESSIONALS Data collected each day by CoCoRaHS volunteers are used by many professionals across the country –weather forecasters, hydrologists, in water management, by researchers, in agriculture, by climatologists, in the insurance industry, engineering, recreation and many others. Who Uses CoCoRaHS Observations Some examples of how your data reports are used include: These are just a few of the questions that you will be helping answer. It will take time before we have good answers to all these questions. Each season we are learning more and more. Your data will help in many ways.
