FLEXPART meteorological input from ECMWF

In order to extract data from the ECMWF MARS archive, one needs access to ECMWF. For publicly available data like reanalyses this is open to everyone and it is sufficient to register at the ECMWF web page. For other specialised data a member-state or special-project account may be required.

Software for retrieving ECMWF data in the specific format needed by FLEXPART is kindly provided by Leopold Haimberger, Gerhard Wotawa, and others:

• ECMWF data retrieval software, V2.1
• ECMWF data retrieval software, V4, allows to retrieve compressed ECMWF data on old AIX ecgate in mixed GRIB1/GRIB2 coding
• ECMWF data retrieval software, V4.1, allows to retrieve compressed ECMWF data on new Linux ecgate in mixed GRIB1/GRIB2 coding
• flex_extract_ecgate_V6.0.tar.gz, a new version for retrieval with 1h time resolution and other enhancements
• flex_extract V7.0.2 New, python-based version. Allows access to publicly available data without a member state account.
