HCMN Rainfall project #803 has been updated to utilize the CoCoRaHS system. CoCoRaHS is an acronym for the Community Collaborative Rain, Hail and Snow Network. CoCoRaHS is a non-profit, community-based network of volunteers of all ages and backgrounds working together to measure and map precipitation (rain, hail and snow). CoCoRaHS provides precipitation data for many more sources/location for scientists to use. The Public can view at the historical data in CoCoRaHS from their website if you know the name of a site (TX-152-HYS is John Kluth’s). CoCoRaHS started in 1998, and has representation in all 50 states, Canada, and the Bahamas. View the CoCoRaHS website.
The requirements for becoming a CoCoRaHS volunteer, and thus be a part of Project 803 is a 4-inch diameter Rain Gauge. You may purchase one from a link found on the CoCoRaHS website. It has a capacity of up to eleven (11) inches of rainfall. You will also need to apply/register yourself as a volunteer which also is done from the CoCoRaHS website.
Once you have registered, you will be assigned an ID and a password to login to their system. You may log your observations on their website or you can download their APP to your Smartphone. This is a fast and easy way enter your data. Follow the instructions and recommendations on where to locate the gauge to increase measurement accuracy.
We will be making a large order for the new training class, which will be available of trainees (for any that wish to purchase one of these gauges. When we prepare to do that, watch your emails to find out when and who to contact to be included in that order. By being a part of a large order, you save on the shipping costs. You will need to be willing to attend a Chapter or Training meeting to be able to pick-up the rain gauge if you participated in a large order.
Please note that the HCMN Board recently decided that the maximum amount of volunteer time (VT) you may log per month for this project is 2.5 hours. This is based upon observing and logging data daily, with the estimate that it takes about 5 minutes each day to do so. Please only log the actual amount of time you spend, capped at 2.5 hours, for each month of your observations. Thus if you miss some days of logging (due to being out of town), and then enter a Multi-Day Report, you would therefore be logging multiple days of data, but only spend 5 minutes of time to do so.
Below are some screen shots from the CoCoRaHS phone app. This is from John Kluth’s CoCoRaHS login. He resides full-time in Northwest Harris County, part-time in far North Hays County. He has both of his properties registered with CoCoRaHS, and observes and records rainfall from both sites. He only logs into VMS the time each month that he empties his gauge in Hays County, thus much less that 2.5 hours per month for him.
