    84 The standard data provided is from ECMWF's operational data. It is a deterministic forecast from the atmospheric model, version 1, analysis.

    86 The GRIB start dumps are created by concatenating the following fields: 
     84GRIB format start dumps can be created from ECWMF MARS data. The GRIB start dumps are created by concatenating the following fields: 
    8785 
    8886 * skin temperature, 
     
    9492 * U and V wind velocities 
    9593 
     94This is the minimum necessary to start the UM. 
     95 
     96These fields can be provided from the ERA Interim, ERA5 or other databases.  There are a number of scripts available to create these. 
     97 
    9698The script [attachment: get-start] gets a start dump.  It should be run on ECMWF computer `ecgate`.

    105107If your UM model is currently using a Met Office start dump and you need to use a GRIB start dump, you will need to modify your UM model set up.  You will need to tell it you are using a GRIB file and also modify the reconfiguration to supply the fields that are missing in the GRIB start dump.
