abstract:
An intercomparison of retrieval errors from different Tropical Rainfall
Measuring Mission (TRMM) passive microwave products was carried out to
assess the definition of observation error for experiments of rainfall
assimilation in a variational framework. Depending on algorithms and their
spatial resolution and sampling, a large variety of error estimates
occurred. The error propagation to the European Centre for Medium-Range
Weather Forecasts (ECMWF) model grid (here 45 and 60 km) was investigated
from error simulations and observed data with and without accounting for
spatial error correlation.
