<p>From 2018 to 2023, CoCoRaHS saw continued growth and more changes:</p> <p>The coronavirus pandemic, that started in 2020, showed that CoCoRaHS was the perfect stay-at-home activity. March and April 2020 proved to be one of our best months yet and our entire network saw over 5,700 new signups during 2020.</p> <p>Social distancing was important during the coronavirus pandemic, and our observer from Crested Butte CO, billy barr (CO-GN-18) became a celebrity and an incredible recruiter for our network with his &ldquo<br />Tips from someone with 50 years of social distancing&rdquo<br /> CoCoRaHS was something many of us did, just to keep track of something.</p> <p>While we stayed close to home during 2020, the same applied to members of our CoCoRaHS Headquarters staff. After hours of online meetings, while none of us were able to travel, we finally put the finishing touches on years of development and testing and rolled out our new interactive map. maps.cocorahs.org The new map has been a wonderful gift to us and to our user community. For the first time, we can combine daily reports with multi-day reports and display those totals on this map, which contributes to drought monitoring as well as tropical cyclone storm totals.</p> <p>2021 saw another significant change with CoCoRaHS. Since 2010, Water Year Summaries were generated each year by state, once in October and again in November. This process was very computer intensive and only captured data at those points in time. With the change we have made, Water Year Summaries are now dynamic, updated with each report that is made. Look at wys.cocorahs.org.</p> <p>CoCoRaHS continues to expand. At the request of the National Weather Service, the Pacific Island of Guam was added to our network in September 2022. This addition proved to be different than adding any of our previous states and countries. Guam is the very first location we have added in the Eastern Hemisphere, so all our latitude and longitude figures, as well as time zone adjustments for local reports, had to be made to accommodate this far away island.</p> <p>The American Meteorological Society (AMS) met in Denver, Colorado during January 2023. CoCoRaHS was given the chance to feature itself and its contributions to science. Several fifteen minute sessions were made, highlighting the impacts CoCoRaHS has made during its 25 years.</p>
