## 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.

## 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.

## 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).
