We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition. Read about the Web Unification Project

Methane emissions detected by GHGSAT over the volcano Mount Fentale, Ethiopia on January 31, 2025 at 07:59:33 UTC. The image shows a Mapbox basemap satellite image of the volcano with the GHGSAT-detected emissions data superimposed on top. A rainbow colour ramp for the plumes shows the enhancement of methane above local background levels in parts per billion, with dark blue as low and bright red as high. The emission rate is estimated to be 58 metric tonnes per hour.

This 2024 Normalized Difference Vegetation Index (NDVI) image from the HLS project shows the degree of land use change in a region of Western Brazil. Green areas with high NDVI values indicate healthy vegetation while tan and brown areas with low NDVI values indicate soil or barren areas.

The Harmonized Landsat Sentinel-2 Project Releases Vegetation Indices

These new vegetation indices offer the same near-global coverage, and 30-meter spatial resolution as the initial HLS products.
