The idea is to start with archiving of the former EURO4M outputs in MARS the same way as UERRA data will be stored in the future.

Solution chosen:

  • original data in GRIB1 (no common definitions of the parameters) for period 2008-2009
  • 15 selected surface parameters only

List of parameters to be stored from EURO4M into MARS

@grib parameter description in the table: unit, parameter number/Id, table number (LTYPE), level

@Precipitation: We would like to have total, large-scale, and convective precipitation, rainfall, and snowfall available. In order to achieve that it is necessary to only store two of the total, large-scale, convective and precipitation, rainfall, snowfall combinations. Is this abundance of precipitation output of scientific value or is, e.g., total precipitation sufficient?

  1. I don't think splitting precipitation into subtypes is that scientifically useful as it is model dependent.

  2. Anonymous

    So, are you saying that total precipitation would be sufficient to start with?

     

  3. Others might object though

  4. Hi Peter, I hope I'm correctly logged in now and my Name (Michael) is shown.

    Thanks for commenting. I've initially put it into the table because I thought that convective precipitation, and maybe also snowfall, would be important output of the regional reanalyses which are worth evaluating.
