Description

The MODIS sensors aboard the twin satellites Aqua and Terra provide global coverage of earth’s surface every 1 to 2 days. MODIS’s spatial, spectral, and temporal resolution allow for imagery to be utilized for regional monitoring of vegetation, land surface temperature, and the environment.

USGS MODIS SSEBop ET product provides actual evapotranspiration (ETa) values across the globe. ETa the water that is consumed by plants during transpiration plus the water that is evaporated from the soil surface and is a major component of the water budget.

USGS MODIS SSEBop ET product estimates ETa using the remote sensing ET model known as the operational Simplified Surface Energy Balance (SSEBop) (Senay et al., 2011). This model uses land surface temperature to estimate a fraction of reference ET (ETf) through a thermal index approach. ETf is linearly interpolated between available scenes and multiplied by the reference ET.
