Data DescriptionMicrowave Integrated Retrieval System Daily Mapped Files - The MIRS was developed with an end-to-end capability of calibrating and characterizing the radiances measured from satellite-based microwave instruments and retrieving the environmental data records with state of the art algorithm science. This system is an upgrade from the NESDIS operational Microwave Surface and Precipitation Products System (MSPPS) and is a one-stop resource for microwave-derived products from various polar-orbiting satellite instrument configurations. The MIRS is capable of optimally retrieving atmospheric and surface state parameters and provides physical-based retrievals/products in a consistent fashion. It is also designed to be instrument/spectrum-independent, parameter-independent, and platform-independent. 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. Current instruments are the Advanced Microwave Sounding Unit-A (AMSU-A) and the Microwave Humidity Sounder (MHS) onboard NOAA-18 and MetOp-A satellites and the Special Sensor Microwave Imager/Sounder (SSMIS) aboard the DMSP 5D-2/F16 satellite. Current operational mapped products are total precipitable water over ocean and land, land surface temperature, land surface emissivity, cloud liquid water, sea ice concentration, snow water equivalent, snow cover, ice water path, rain water path, liquid water path, and rainfall rate available in HDF-EOS 4 format.
