Known Bugs and Issues ********************* Release v7.1 ============ CDS API and ERA5 data --------------------- See ticket `#230 `_ on flexpart.eu for information. Installation problems with ``GATEWAY`` and ``DESTINATION`` parameters --------------------------------------------------------------------- See ticket `#263 `_ on flexpart.eu for information. Fixed in v7.1.1. Installation problems with the Fortran program ``calc_etadot`` -------------------------------------------------------------- See ticket `#264 `_ on flexpart.eu for information. Fixed in v7.1.1. ECCODES Error Code 250 ---------------------- If you get an error message from ECCODES with code 250, looking like this: .. code-block:: bash ECCODES ERROR : wrong size (184) for pv it contains 276 values ECCODES ERROR : get: pv Passed array is too small ... ERROR CODE: 250 ... ERROR MESSAGE: Command '['/flex_extract_v7.1/Source/Fortran/calc_etadot']' returned non-zero exit status 250. ... FORTRAN PROGRAM FAILED! then you have set a wrong maximum level in the :literal:`CONTROL` file! It is important to properly select the maximum level depending on the data set you would like to retrieve. Only the following values of the number of model levels available are valid: 16, 19, 31, 40, 50, 60, 62, 91, 137. The ERA-Interim data set uses 62 model levels and *ERA5* as well as *CERA-20C* uses 137. The operational data sets use different numbers, depending on the date. For example, from 25/06/2013 on, 137 model levels were used in the operational system. Therefore, every time you extract data from a date later than 25/06/2013 you have to select LEVEL=137 in the :literal:`CONTROL` file, or you have to define LEVELLIST=1/to/137. Of course, you can stop before the top of the atmosphere, such as 60/to/137, but you have to include the maximum level number (i. e., the lowest level, see note below!) number as the last one. Table 2 in the `scientific model description paper `_ gives an overview of the level lists and the corresponding date they were introduced. .. note:: Be aware that the ECMWF model counts the levels from the top of the atmosphere downward to the surface. Level 1 is the topmost level, and e.g. 137 would be the level closest to the ground.
