About 

The operational Microwave Integrated Retrieval System (MiRS) aims to upgrade the NESDIS current operational Microwave Surface and Precipitation Products System (MSPPS) and build a one-stop shop for microwave products from various satellites with different instrumental configurations. With the capability of providing optimal and physically-based retrievals of atmospheric and surface state parameters, the operational MiRS will produce advanced near-real-time surface and precipitation products in all-weather and over all-surface conditions using brightness temperatures from the microwave instruments. Ice Concentration, Snow Cover, Snow Fall Rate, and Snow Water Equivalent products are available by subscription from PDA (but not sent over SBN).

Limitations

Ground Resolution: The resolution varies greatly as the data points veer from nadir. Information from the outer edges of the viewing range is unreliable.

View Infrequency: A single area is only viewed twice per day.

Lag: Data refreshes every 90 minutes.

AWIPS 

Location: Satellite → S-NPP and NOAA-20 → Derived Products → ATMS Products

Color Maps: Grid/Gridded Data

Sampling: SIC: % ; SNOW: (binary); SFR: mm/hr; SWE : cm

Quality Flags: Qc: 0-good, 1-usable with problem, 2-bad

Technique: The Advanced Technology Microwave Sounder (ATMS) operates in conjunction with the CrIS to profile atmospheric temperature and moisture. Higher (spatial, temporal and spectral) resolution and more accurate sounding data from CrIS and ATMS support continuing advances in data assimilation systems and NWP models to improve short- to medium-range weather forecasts.
