    11 Software for retrieving ECMWF data in the specific format needed by FLEXPART was originally created by Gerhard Wotawa. The later versions were written by Leo Haimberger on behalf of CTBTO. v7.0.3 together with Anne Philipp.

     12 *  Since v7, this software has been given the name '''flex_extract''' (before, various names were used to refer to it).
     13 * Originally, this software was usable for member-state users only. '''From v7.0.3 on, retrieving public datasets as non-member-state user is supported.'''

     23|| [download:62 7.0.4]|| ||A bugfix version which solves problems with ERA5 and CERA retrieval from v7.0.3 and added two new features: It can retrieve analysis and forecast ensembles efficiently, e.g. by setting `number=0/to/9` (suffix for the ensemble member number is added to output file names). Additionally, it can write an extra file `mars_requests.csv` which contains all MARS request parameters for each request. ||
