Cloud Retrieval Validation Experiment

Summary:
ECMWF model fields have been extracted for the PIDCAP, CLOREVAL/1 and ACE-2 experiments and LWP data have been retrieved from the SSM/I (Special Sensor Microwave/Imager) data using the one-dimensional variational (IDVAR) method for the last two experiments when SSM/I data were available. The SSM/I 1DVAR LWP retrievals have been compared to other algorithms retrievals and have shown demonstrable improvements over many of the older algorithms, including some used quite widely. ECMWF will use the results CLOREVAL to (a) help in the development of assimilation of LWP data into their NWP forecast model and (b) validate cloud analyses and forecasts within the model.
