UM/GettingInitialData
v5 v6 1 1 = Getting Initial Data = 2 2 3 Start dumps, LBC files and ensemble data can be obtained from the Met Office M OOSEdatabase. This covers the latest five years. Start dumps from earlier periods can be constructed as GRIB files from ECMWF data.3 Start dumps, LBC files and ensemble data can be obtained from the Met Office MASS database. This covers the latest five years. Start dumps from earlier periods can be constructed as GRIB files from ECMWF data. 4 4 5 5 To get the data, create a help desk ticket providing the following information, … … 8 8 * project name, 9 9 * estimate of the data volume in GB, 10 * where in M OOSEthe 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. 11 11 12 12 13 13 == Getting data from the Met Office == 14 The start dumps are now stored in M OOSE, which can be accessed via MONSooN.14 The start dumps are now stored in MASS, which can be accessed via MONSooN using the MOOSE interface. 15 15 16 16 To get data for 28/Sep/2011 we would type, … … 96 96 Also in the mogreps-g path you need the boundary files: E.g. 20110722_qweg00.oper??.FRAMES.EY.tar.gz. 97 97 98 99 100 98 101 99 102 100 == Getting data from ECMWF == 101 The 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. 102 Data 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 111 112 In contrast a UM dump contains typically a hundred fields. So the GRIB start dumps need to be reconfigured. 103 113 104 114 105 [wiki:WMcGinty W. McGinty], 15 Oct 2015 115 116 117 [wiki:WMcGinty W. McGinty], 3 Nov 2015
