Relative Soil Moisture (0% wilting, 100% saturation) in the 0-2m (total column) layers. The near-surface layer responds quickly to heavy rainfall and indicates near-saturated conditions conducive to significant runoff and flash/river flooding, while the deeper column layers represent longer-term water storage via infiltration from upper layers. The Image Service is published using a Raster Mosaic populated with GeoTiffs collected from the Global Hydrology Resource Center (GHRC) SPoRT FTP site daily. <\/SPAN><\/P><P><SPAN STYLE=\"font-weight:bold;\">Data Visualization:<\/SPAN><\/P><P><SPAN>Relative Soil Moisture (RSM) is shown using a Classified Color Ramp (Multi-Color, 20 classes). Each class represents percentage of volumetric soil moisture.
