Table 21.6: Level 2a products for precipitation monitoring with MIMR (resolution from 36.5
GHz channel).
Table 21.7 shows the foreseen Level 2b products. These are on a monthly basis and the accuracies shown assume that morning and afternoon instruments are used. If only one instrument
is used the accuracies of these products will be severely degraded since the diurnal cycle of
precipitation will be sampled only once. Results recently published indicate that there may
be two daily peaks for the probability of occurrence of rain in the tropics and these occur at
different times over the ocean or over land. The use of a AM and PM platforms has also an
impact on the Level 2a products (pixel level) in Operational Meteorology.
