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.
