The goal of the Soil Moisture Visualizer (SMV) is to bring together multiple sources of soil moisture data available for North America into a single platform for visualization and download. The visualizer harmonizes surface and root zone soil moisture data sets that are in diverse native data formats and encompass a range of spatial footprints, soil depths, and measurement frequencies. The SMV consists of a web-based application for visualization and spatial subsetting of the soil moisture data and accompanying REST-based services (being developed) for accessing the data.
