  1. Extension of Geophysical Monitoring/Validation to ECMWF Presented by Flavio Iturbide-Sanchez

  2. The European Centre for Medium-Range Weather Forecasts (ECMWF) Data • ECMWF data is gridded Binary (GRIB) data • Numerical Weather Prediction (NWP) model with a resolution of 0.25 deg in latitude and longitude. • Latitude ranges from 90.0 to -90.0 deg and Longitude from 0.0 to -0.50 deg. • Atmospheric parameters can be provided with 31, 40, 50, 60 and 91 levels.

  3. The Skin Temperature in Kelvins using the Grid Analysis and Display System (GrADS)

  4. Manipulation of the ECMWF data Extract and organize ECMWF data into binary files using the WGRIB program and a Perl script. Re-grid the extracted data from 1440x760 to 360x181 points to reduce the amount of data and to standardize it. The extracted data has to be organized (atmospherics parameters are extracted from the higher to the lower pressure levels) The size of a binary file contained just atmospheric parameters is about 2 GB Format the regridded data and provide the required unit conversion to them Program that collocates the ECMWF gridded data into an orbit-based space using radiance measurements ECMWF Reader

  5. Extracted Parameters from the ECMWF Data • Atmospheric Parameters Temperature Humidity Cloud Liquid Water Content Cloud Ice Water Content Ozone • Surface Parameters Skin Temperature 2 meter Temperature Surface pressure 10 meter U- and V-Wind Component Land/Sea Mask

  6. Atmospheric Profiles obtained from the ECMWF Reader

  7. Atmospheric Profiles obtained from the ECMWF Reader
