The 4-inch Plant Available Water map is based on the 24-hour-averaged plant available water for the top 4 inches (10 cm) of soil under the existing vegetation at each Mesonet site for the previous day. Plant available water under other vegetation types may differ. Plant available water is the amount of water in the soil that is potentially available for plant uptake. Technically, it is calculated as the amount of soil water at matric potentials above -1500 kPa. The maximum possible plant available water varies between sites due to soil differences. Most plants experience water stress when less than 50% of the maximum plant available water remains in the active root zone. This map is updated once each day between 7 and 8 AM.
The 16-inch Plant Available Water map is based on the 24-hour-averaged plant available water for the top 16 inches (40 cm) of soil under the existing vegetation at each Mesonet site for the previous day.

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.
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.
The Daily Averaged Fractional Water Index at 24 inches map displays the 24-hour-averaged soil moisture at 24 inches (60 cm) under native sod for the previous day.

The 7-Day Change in Fractional Water Index map displays the change in soil moisture at 10 inches (25 cm) over the past week Positive numbers indicate an increase in soil moisture, while negative numbers indicate a decrease in soil moisture. This map is updated once each day between 7 and 8 AM.
