Probability-Matching Method

• Developed for radar usage

• Replicate PDF of P(Z) to P(R)

• Tuned to local climatology

over a space-time domain

• For satellite, P(Z) P(TB)

• Dynamically tune with SSM/I

rain as new passes arrive

• Relation is instrument-specific

• Match PDF moments to

distribute (Z,T) pairs

over higher rain rates

(m=1 works nicely)
