Note
titleENS extended events

  1. Event ext00h1104 will be triggered daily, when the ENS Extended forecasts are available, cf. our dissemination schedule. If you want to keep using ENS Extended data only on Mondays and Thursdays, like before the implementation of cycle 48r1, you will have to add some testing on the day of the week in your TC-1 job. This can be done with the 'date' command, e.g. in the KSH:

    No Format
    day_of_week=$(date +%a --date=$MSJ_YEAR$MSJ_MONTH$MSJ_DAY)
case $day_of_week in
    Mon|Thu)
    echo 'I extract the ENS extended data on Mon and Thu ...'
    *) ;;
esac


  2. Event ext00h1104ref will be triggered when the ENS extended re-forecasts are first generated. This is about 2 weeks or so before the availability of the ENS reforecasts following the dissemination schedule (the MSJ_ date variables will point to a date about 2 weeks ahead of the current date).

  3. Please remember to use the MSJ_ varaibales variables defined for you in your TC-1 jobs. I.e. by using the MSJ_EXPVER variable in your MARS requests, your TC-1 jobs will work before and after the implementation date of the - any - new IFS cycle.

...

The ENS forecasting system has its own re-forecasts (MARS streams ENFH and ENWH). A new TC-1 event has been created that will be triggered when these data are first available, about 2 weeks before the official dissemination schedule, like for the ENS extended re-forecasts.

No Format
4302       ef00h360ref          At this stage, the mid-range ensemble reforecast products have been updated.

Other changes.

Two new MSJ_ variables are defined for your convenience in TC-1 jobs:

  • MSJ_MEMBERS contains the number of (perturbed) members if the forecast stream, e.g. currently 100 members for ENS extended or 10 members for the re-forecasts.
  • MSJ_IFS_CYCLE contains the IFS cycle in use.

See hereafter for an example with the full list of MSJ_ variables defined in an ENS Extended re-forecast TC-1 job.

MSJ_DAY=22
