Description
NOAA's Global Hydro-Estimator provides a global mosaic of rainfall estimates from multi-geostationary satellites. The algorithm includes GOES-16, GOES-15, Meteosat-8, Meteosat-11, and Himawari-8. Products include instantaneous rain rate and 1-hour, 3-hour, 6-hour, 24-hour, and multi-day rainfall accumulations.
Use Cases
Modeling flood risk based on multi-day rainfall accumulation data
Analyzing regional precipitation trends based on hourly and daily rainfall estimates
Calibrating other rainfall sensors based on satellite-derived instantaneous rain rates
Studying storm system development based on time-series accumulation products
Strengths
Data is sourced from five operational geostationary satellites, providing broad coverage
Products include six distinct temporal aggregations from instantaneous to multi-day
Algorithm provides a global mosaic, offering a unified view
Limitations
Description metadata is limited; actual data quality requires manual inspection after download
Column-level documentation is absent; field semantics must be inferred after download
