    58 The UKV start dumps are in MASS with path names like, 
     54The UKV start dumps use a non-regular, or variable, grid. The UKV start dumps are in MASS with path names like,

    9389== Getting data from ECMWF == 
    9490The 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. 
    95 Data prior to X is in GRIB1 format, after that it is GRIB2.  The GRIB start dumps are created by concatenating the following fields: 
     91Data 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: 
    9692 
    9793 * skin temperature, 
     
    10399 * U and V wind velocities 
    104100 
    105 In contrast, a UM dump contains typically a hundred fields, so the GRIB start dumps need to be reconfigured. 
     101In 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.
