NASA's Worldview application allows users to discover and download more than 1,200 visualized satellite data products—a collection that was recently expanded to include Global Precipitation Measurement (GPM) data products from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG). IMERG gathers data from a constellation of satellites covering our entire planet, and provides high-quality precipitation estimates even for remote areas that have no ground-based instruments. The IMERG database is updated hourly, making it useful for tracking weather events, and these data also help researchers understand the water cycle and and aids decision-makers working in agriculture, public health, energy, and transportation.
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.
