Featured Soils Observation Method: MODIS
The Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Aqua and Terra platforms continually collects global data approximately every two days. One MODIS product, normalized vegetation difference index data, can be used to predict how much carbon dioxide is emitted from soils, which is major component of the global carbon cycle. Carbon is released in the process called soil respiration and driven by the decomposition of surface litter through microbial activity.
Researchers taught the SatVision Top-of-Atmosphere foundation model to recognize MODIS imagery features.

The Visible Infrared Imaging Radiometer Suite (VIIRS) will help ensure continuity of Earth observations after the upcoming retirement of the Moderate Resolution Imaging Spectroradiometer (MODIS).
Learn how to access and use Moderate Resolution Imaging Spectroradiometer (MODIS) Version 6 land data.
Remote sensing data's drought-indicating parameters are essential to manage the impact of water scarcities and minimize drought losses.
