MiRS System

Team Lead: 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
