    3939The script deals with dates from the earliest time 2006/01/01 0Z and is know to work up to 2019/06/26.

    41 To find out whether the data exists, 
    42  
    43 {{{ 
    44 moo ls moose:/opfc/atm/global/rerun/201109.file 
    45 }}}

    4742Generally, we prefer to get the output from the global runs - these have "qwqg" in the title; otherwise we get the global update - these have "qwqu" in the file name.

    90 The standard data provided is from ECMWF's operational data. It is a deterministic forecast from the atmospheric model, version 1, analysis. It is not ERA. 
     85The standard data provided is from ECMWF's operational data. It is a deterministic forecast from the atmospheric model, version 1, analysis. 
    9186Data prior to a certain date is in GRIB1 format, after that it is GRIB2.  The GRIB start dumps are created by concatenating the following fields: 
    9287 
     
    9994 * U and V wind velocities 
    10095 
    101 In contrast, a typical UM dump contains fifty to 150 fields, so the GRIB start dumps need to be reconfigured by a UM model with a suitable scientific set up. 
     96The script [attachment: get-start] gets a start dump.  It should be run on ECMWF computer `ecgate`. 
     97 
     98The command is  
     99{{{ 
     100get_start yyyy mm dd hr 
     101}}} 
     102 
     103with spaces between the date components.
