Enterprise Rain Rate
The enterprise L2 Rainfall Rate product provides a numerical estimate of rainfall rate in millimeters per hour from GOES-16, GOES-18 and Himawari-9. The data format is NetCDF4, data coverage is full disk, data frequency is 10 minutes, and resolution is 2km
GOES, Himawari | Resolution: 2km | Frequency: 10 min
Hydro-Estimator Rainfall
The Hydro-Estimator (HE) algorithm combines infrared brightness temperatures to detect rainfall and calculate rainfall rates. It also incorporates data from the NCEP Global Forecast System (GFS) to consider factors like moisture availability, evaporation, orographic modulation, and thermodynamic profiles.
GOES | Resolution: 4km | Frequency: 15 min; 1 hr on AWIPS
Microwave Integrated Retrieval System (MIRS)
Microwave Integrated Retrieval System (MIRS). The MIRS is a one-stop resource for microwave-derived products from various polar-orbiting satellite instrument configurations. The MIRS produces advanced near-real-time operational surface and precipitation products in all-weather and over all-surface conditions using brightness temperatures from multiple microwave instruments.

Blended Total Precipitable Water
The blended TPW products merges the TPW retrievals from various satellites/sensors/algorithms, currently including MetOP-B, Metop-C, S-NPP, NOAA-20, NOAA-19, GCOM-W1 and GPM Microwave Imager (GMI) from Global Precipitation Mission (GPM), and also Met-GPS, to provide an hourly unified global TPW map in supporting of the NWS users’ need.
MetOp, JPSS, GCOM-W1, GPM | Resolution: 4km | Frequency: Hourly
Advected Layered Precipitable Water (ALPW)
One global ALPW NetCDF4 (AWIPS-2 systems compatible) file is produced every hour, ready for use throughout the NWS. It contains geophysical data and metadata. The geophysical datasets are floating point arrays on the global Cylindrical Equidistant (CE) projection (1251 rows x 2501 columns). ALPW consists of four layers (surface-850 mb, 850-700 mb, 700-500 mb, 500-300 mb) of layer precipitable water and has units of mm or inches, chosen based on forecaster interest and the information content of the MiRS soundings from which LPW is derived.
MetOp and JPSS | Resolution: 16km | Frequency: Hourly
Blended Rain Rate
The blended rain rate (RR) product is produced hourly by blending together recent rain rate retrievals from passive microwave instruments on eight polar-orbiting satellites, including POES NOAA-19, NOAA-20, MetOp-B, Metop-C, S-NPP, GCOM-W1, GPM, DMSP F17 and F18. The blended RR eliminates the bias between those data sets and provides a unified, meteorologically significant rain rate field for satellite analysts and weather forecasters.
POES, MetOp, JPSS, GCOM-W1, GPM, DMSP F17 and F18 | Resolution: 4km | Frequency: Hourly
Snowfall Rate
SFR is the instantaneous liquid-equivalent snowfall rate. It is retrieved from measurements taken by passive microwave sensors aboard certain polar-orbiting satellites(Metop-B, Metop-C, SNPP, N20, N21, and GPM).
Metop, JPSS, and GPM | Resolution: 4km | Frequency: Daily
GCOM precipitation products
The AMSR-2 instrument onboard the GCOM-W1 satellite will continue Aqua/AMSR-E observations of water vapor, cloud liquid water, precipitation, sea surface temperature, sea surface wind speed, sea ice concentration, snow depth, and soil moisture. NESDIS processes GCOM-W1 data and generates NOAA unique operational products for users.
GCOM-W1 | Resolution: 4km | Frequency: Daily
Ensemble Tropical Rainfall Potential (eTRaP)
The eTRaP is a composite ensemble based on 6-hourly totals from single-orbit TRaPs. It provides deterministic and probabilistic forecasts for four 6-hour intervals and a 24-hour cumulative period.
Metop-B, Metop-C, SNPP, N20, GCOM, and GPM | Resolution: 4km | Frequency: 6 Hours
