Some Past Efforts in Merging SSM/Iand Geostationary IR Data

• Adler et. al, 1991,1993
  • calibration coefficients from SSMI rain rates vs. IR rain rates (monthly, 1-degree)

• Vicente, 1994
  • first work on SSMI-calibrated instantaneous geo-rain rates

• Berg, 1994
  • calibration of rain probability and rain amount distributions by IR temperature distributions
    (5 days, 2.5-degree)

• Jobard and Debois, 1994
  • training of rain cloud classification by 3-D
    histograms (1-12 hours, 15-120 km)

• Vicente et. al, 1998
  • radar-adjusted IR with NWP model adjustments (instantaneous, 30 km)
