Hi, my name arie, I want to ask something about validation an correction data
TRMM

my study area is an mountain region, I compare the TRMM data and ground
observation, but the error result is too big,sometimes the TRMM is underestimate
and sometimes overestimate so the correlation is very small. I think it's
because Orographic factor, did anyone know how to or methods to correct the TRMM
data (daily data)

thanks
