2-inch Fractional Water Index

The Daily Averaged Fractional Water Index at 2 inches map displays the 24-hour-averaged soil moisture at 2 inches (5 cm) under native sod for the previous day. Fractional water index ranges from 0 (completely dry) to 1.0 (completely saturated). Soil moisture can not be measured if the soils are frozen. This may cause our maps to have large areas of missing data during the winter months. This map is updated once each day between 7 and 8 AM.

10-inch Fractional Water Index

The Daily Averaged Fractional Water Index at 10 inches map displays the 24-hour-averaged soil moisture at 10 inches (25 cm) under native sod for the previous day. Fractional water index ranges from 0 (completely dry) to 1.0 (completely saturated). Soil moisture can not be measured if the soils are frozen. This may cause our maps to have large areas of missing data during the winter months. This map is updated once each day between 7 and 8 AM.
