• Over Land: GWP (IWP) and RWP
• Over Ocean: GWP (IWP) , RWP, CLW ,TPW

Generate the MIRS Rain Rate Using a Regression Algorithm that Combines the MIRS
Products
• Over Land: MIRS RR = Ao + A1*IWP + A2*RWP
• Over Ocean:
MIRS RR = Ao + A1*IWP + A2*RWP + A3*TPW + …
where Ai are regression coefficients

Future Work
• Work on a new rain rate algorithm based on TRMM data products.
• For validation and inter-comparison purposes, make the MIRS rain rate suitable for its inclusion in the International Precipitation Working Group (IPWG) project.
