If the result is a positive number, the region was wetter than average. To calculate the difference-from-average precipitation values shown on these maps-also called precipitation anomalies-NCEI scientists take the total precipitation in each 5x5 km grid box for a single month and year, and subtract its 1991-2020 average for the same month. To fill the grid where station data doesn’t exist, a computer program interpolates (or estimates) values, accounting for the distribution of stations and various physical relationships, such as the way temperature changes with altitude. After scientists check the quality of the data to omit any systematic errors, they calculate each station’s monthly total and plot it on a gridded map. Volunteer observers or automated instruments gather the data and submit it to the National Center for Environmental Information (NCEI). Daily measurements of rain and snow come from weather stations in the Global Historical Climatology Network (GHCN-D).
