Precipitation product code format
P-<precipitation type>-<input data>-<algorithm/technique (only when significant or confirmed)>
<precipitation type>
IN = Instantaneous Precipitation Rate, AC= Accumulated Precipitation , DM= Daily Mean
<input data/products>
Refers to: the radiometer (e. g. SSMIS) or to channels frequencies (e. g. PMW) or to the satellite in case of multiple inputs from different radiometers of the same satellite (e.g. MTG when FCI and LI), or specific input products (e.g. SM2RAIN); E=East
<algorithm/technique>
CO=Convective Precipitation , SF= Snow Fall, IC=intercalibrated
