    22 
    3 Start dumps, LBC files and ensemble data can be obtained from the Met Office MOOSE database.  This covers the latest five years. Start dumps from earlier periods can be constructed as GRIB files from ECMWF data.

    55To get the data, create a help desk ticket providing the following information, 
     
    88 * project name, 
    99 * estimate of the data volume in GB, 
    10  * where in MOOSE the data is located if it is not one of the standard sets below. 
     10 * where in MASS the data is located if it is not one of the standard sets below.

    14 The start dumps are now stored in MOOSE, which can be accessed via MONSooN.

    9696Also in the mogreps-g path you need the boundary files: E.g. 20110722_qweg00.oper??.FRAMES.EY.tar.gz.

    102100== Getting data from ECMWF == 
     101The standard data I provide is from ECMWF's operational data. It is a deterministic forecast from the atmospheric model, version 1, analysis. It is not ERA. 
     102Data prior to X is in GRIB1 format, after that it is GRIB2.  The GRIB start dumps are created by concatenating the following fields: 
     103 
     104 * skin temperature, 
     105 * surface pressure, 
     106 * land-sea mask, 
     107 * geopotential, 
     108 * temperature, 
     109 * specific humidity, 
     110 * U and V wind velocities 
     111 
     112In contrast a UM dump contains typically a hundred fields.  So the GRIB start dumps need to be reconfigured.
