Description:
Abstract:
This Level 3 (gridded) data set’s land surface parameters, surface soil moisture, land surface (skin) temperature, and vegetation water content, are derived from passive microwave remote sensing data from the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI), using the Land Parameter Retrieval Model (LPRM). There are two files per day, one day and one night, archived as two different products. This document is for the daytime product. The data set covers the period from December 1997 to present, at a spatial resolution of 0.25 degree. The data are stored in netCDF format. The LPRM is based on a forward radiative transfer model to retrieve surface soil moisture and vegetation optical depth. The land surface temperature is derived separately from TMI's Ka-band (37 GHz). A unique feature of this method is that it can be applied at any microwave frequency, making it very suitable to exploit all the available passive microwave data from various satellites. Input data are from the TMI Brightness Temperatures (1B-11) product, daytime passes, as processed using LPRM (i.e., LPRM/TMI/TRMM L2 product, GES_DISC_LPRM_TMI_SOILM2_V001).

Attribute_Accuracy_Report:
The LPRM/TMI data are sensitive to both internal model limitations and external processes and are screened for the presence of snow/frozen soils, water, and dense vegetation covers. All screened out data pixels are flagged and indicated by a non-data value. A soil moisture uncertainty parameter at X band is included (Parinussa et al., 2011).
