METEOSAT, GMS and GOES), temperature/moisture profiles from
polar orbital satellites of NOAA, USA were validated and successfully
implemented in data assimilation system at NCMRWF.

In order to investigate heavy precipitation
episodes associated with an active monsoon phase, two meso-scale
models ETA (32 km resolution) and MM5 (90, 30 and 10 km resolution)
were implemented. Continuous efforts are made to validate
and improvise the forecast products from these models by analyzing
the model parameters during different significant events like
heavy rainfall, land slides, cloud bursts, gale winds etc.
Several scientists from NCMRWF travelled
abroad either on deputation or fellowships to conduct research
or attend international seminars.
