+  "description": "Daily total precipitation (mm) from NASA's Integrated Multi-satellitE Retrievals for GPM (IMERG) Version 07, accumulated from the half-hourly Level 3 product using Giovanni. IMERG combines precipitation estimates from the GPM constellation's passive microwave sensors, the GPM Core Observatory's dual-frequency radar, and geostationary infrared observations into a 0.1 x 0.1 degree gridded field. Early-run (3IMERGHHE) files are available about 4 hours after observation and use forward morphing only; Late-run (3IMERGHHL) files arrive about 14 hours after observation, add backward morphing and a climatological gauge adjustment, and are the higher-quality near-real-time product.
