CoCoRaHS March Madness 2021

"CoCoRaHS March Madness 2021” (our friendly annual recruiting competition between our CoCoRaHS states to see how many new volunteer observers we can recruit during the month of March) comes to the end of its first week.

To view this week's standings and learn more about our contest, visit our March Madness webpage by clicking here: "COCO MARCH MADNESS 2021 PAGE" . Final results posted on April 1st.

Please consider signing-up a friend or relative as a CoCoRaHS observer during our thirty-one day competition. 

Good luck to your state!


The "Total SWE Monday" Habit . . . Please give it a try!

The National Operational Hydrologic Remote Sensing Center utilizes CoCoRaHS reports of precipitation, snowfall, snow depth and the water equivalent of the snow on the ground every day. CoCoRaHS data provide critical "Ground Truth" information that can improve the skill of their products and models. This will improve the accuracy of flood forecasts in the weeks and months ahead. Click here to see how your CoCoRaHS SWE Reports are used by NOHRSC

Their guidance to us has been that if you can only report one day a week it’s best to all report on the same day. Monday was chosen:

"The analysts at NOHRSC prefer a Total Snow Water Equivalent (SWE) observation taken once a week on Monday. The simple reason is that digging cores every day ruins your sample snowfield area (unless you have a big yard or open fields nearby).

A flood of Monday morning SWE reports gives us a better picture of the overall snowpack instead of a few scattered results trickling in throughout the week. Daily total SWE would be great, but let's make "Total SWE Monday" a habit.

(Note: If you have the room, more frequent observations are appreciated, especially when conditions are changing. For areas that only infrequently get snow, there is no need to wait for Monday -- report SWE whenever you have the chance). For instructions on how to take core samples and report the snowpack SWE, please view our on-line training materials on snow: Training Slide Shows or watch the YouTube short animation on: SWE.

Space is limited to 500 attendees, so register today! Those who aren’t able to attend will be able to watch this episode on-line the following day.


Title: Webinar #75 - CoCoRaHS WxTalk: COOP - NOAA's long established citizen observation program
Date: Thursday, March 11, 2021
Time: 1:00 PM Eastern, Noon Central, 11:00 AM Mountain, 10:00 AM Pacific

"Amy Fritz will present on the National Weather Service’s Cooperative Observer Program (COOP). She will share with the audience the history and origin of the program (dating back to 1890), what instruments are used, where the stations are located, what happens to the observations once they are collected, and how the program helps the NWS. She will also talk about how COOP is similar to CoCoRaHS, and how they are different."
