Purpose/Summary:<\/SPAN><\/P>

The NASA-USDA SMAP Global soil moisture data provides soil moisture information across the globe. Monitoring soil mositure can help identify where flooding has occurred due to Cyclone Idai and what areas may be more prone to flooding if future rainfall occurs. This time-enabled dataset shows the evolution of the soil moisture leading up to and after the landfall of the cyclone.<\/SPAN><\/P>

Suggested Use:<\/SPAN><\/P>

High values in blue and green show more saturated (wetter) soil.<\/SPAN><\/P>

Low values in orange and brown show drier soil.<\/SPAN><\/P>

Areas with increased soil moisture may have been flooded during the event, and are generally more prone to flooding if more rain occurs.<\/SPAN><\/P>

Satellite/Sensor:<\/SPAN><\/P>

The data set is generated by integrating satellite-derived Soil Moisture Active Passive (SMAP) Level 3 soil moisture observations into the modified two-layer Palmer model using a 1-D Ensemble Kalman Filter (EnKF) data assimilation approach.<\/SPAN><\/P>
