MRCC Evapotranspiration & Water Balance Maps

Associated Agencies

Midwestern Regional Climate Center

The Midwestern Regional Climate Center (MRCC) produces maps showing evapotranspiration and water balance for certain stations in the Midwest region at 1-day, 7-day, 14-day, 30-day, and 60-day intervals.

The evapotranspiration (ETo) amount shown on the maps is a measured value using an atmometer. Water balance is the difference between precipitation accumulated in a period and the total ETo through that same period.
