Flooding over the south-east Texas observed from the NASA SMAP satellite, which provides enhanced microwave (L-band) sensitivity to the fractional surface water cover (fw) within a ~36-km sensor footprint. The left image shows the fw cover from September 17-21, 2019 during Tropical Depression Imelda, while the right image shows the fw increase from extensive rainfall driven flooding.
