This page contains details of GA7.1+StratTrop suites available.

Remember to always COPY these suites to a new one that you own, rather than checking them out. This will prevent you accidentally over-writing the settings in the original suite.

TS2000 free-running suites

These are year-2000 atmosphere-only timeslice simulations.

UM versions Met Office XC40 Monsoon2 XCS NEXCS ARCHER
UM11.0 u-ay770 u-bb055 u-bb056 u-ba915
UM11.1 u-bd086 Will be produced on request
UM11.2 u-bd036 u-bd683 u-be045
UM11.3
Bit-reprod with UM11.2
u-bg745 u-bg779 u-bg785
  • An example vn11.2 ARCHER suite configured for a 1-day run without archiving and with manual compile is u-be079. A selected set of 3-hourly meaned UKCA diagnostics are also sent to the daily UPK stream.

TS2000 nudged suites

These are year-2000 atmosphere-only timeslice simulations nudged to ERA-Interim reanalysis. Here the nudging files will change with date rather than being a perpetual year, although the forcings are all climatologies.

UM versions Met Office XC40 Monsoon2 XCS NEXCS ARCHER
UM11.0 u-ba749 u-bb202 u-bb210
UM11.1 u-bd267 Will be produced on request
UM11.2 u-bd359 u-bd341 u-bd366
UM11.3 u-bh303

Release notes / Known Issues

All UM versions (vn10.6.1+)

  • Stash items spanning 38:485 to 38:545 i.e. Aerosol surface conc., number conc., load diagnostics: Due to the way STASH is handling and processing these items -when requested using Stash time profiles like TDMPMN, TMONMN, TDAYMN- will be output as exactly 1/3rd of their actual value. Members making use of these items need to scale the values by 3.0.
