Mark Liu, Christopher Grassotti
Product Description
Microwave Integrated Retrieval System (MiRS):
- Enterprise Algorithm System applied to a number of microwave sensors:
Operational: POES (N18/N19), Metop-A and Metop-B (AMSU/MHS), DMSP (F16/F17/F18/F19), Megha-Tropiques (SAPHIR), GPM (GMI), and SNPP/JPSS (ATMS)
Experimental: TRMM (TMI), Aqua (AMSRE), and GCOM-W (AMSR2) - Same executable, forward operator, and covariance matrix for all sensors
- Modular design makes it feasible to run on other MW sensors or in combination with collocated IR measurements

Future Improvements
- Snow (vegetation correction)
- Rainy condition sounding (update a priori constraints)
- Hydrometeors (improvements to CRTM i.e. scattering, precharacterization of precip type, particle size/shape distribution in CRTM, CLW over land for light rain detection)
- Air mass-dependent bias corrections
