Soil texture measured in the field (SMAPVEX08) — SV08ST

In plain English

What it measures. Soil texture information (the makeup of the soil) for study areas used in a 2008 soil moisture field campaign.

How it's made. Pulled from an existing multi-layer soil characteristics database for the continental United States and tailored to each regional study site for the SMAPVEX08 campaign.

How & where you'd use it. Provides ground reference on soil conditions to support soil moisture research, particularly for checking and interpreting satellite-based soil moisture estimates.

Official description

This data set contains soil texture data that were extracted from a multi-layer soil characteristics database for the conterminous United States and generated for each regional study area. Data are representative of the conditions present in the regional study areas during the general timeline of the Soil Moisture Active Passive Validation Experiment 2008 (SMAPVEX08) campaign.
