Service Description:

Background:

Land Information System (LIS) Soil Moisture from NASA’s SPoRT Center The NASA Short-term Prediction Research and Transition (SPoRT) Center runs a real-time version of the Noah land surface model at ~3-km resolution over the Continental U.S. The simulations run the NASA Land Information System(LIS) software, incorporating real-time Suomi-NPP green vegetation fraction, radar/gauge-derived precipitation estimates and atmospheric analysis fields to generate daily modeled analyses of soil moisture at prescribed layers within the Noah model soil column. 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.

Data Visualization:

Relative Soil Moisture (RSM) is shown using a Classified Color Ramp (Multi-Color, 20 classes). Each class represents percentage of volumetric soil moisture. Values at 0% indicate no moisture in soil, inversely values of 100% indicate complete saturation.

Update Frequency:

Daily

Suggested Usage:

Estimating ground water saturation levels during/after heavy rain events.
