With the implementation of IFS cycle 48r1 including the higher resolution ENS system and a separate daily ENS extended run, we are updating the ECaccess TC-1 events, as described below.
ENS extended forecasts and re-forecasts.
All the pre- cycle 48r1 ENS extended forecast related events listed hereafter will be discontinued. See command 'ecaccess-event-list':
284 mofc_all At this stage, the Monthly Forecast real time products have been updated. 809 mofc_mon At this stage, the Monday Monthly Forecast real time products have been updated. 1341 mofc_mon_refc At this stage, the Monday Monthly Forecast raw hindcast data have been generated. 1342 mofc_mon_refc_pp At this stage, the Monday Monthly Forecast post-processed hindcast products have been generated. 3426 mofc_thu At this stage, the Thursday Monthly Forecast real time products have been updated. 1343 mofc_thu_refc At this stage, the Thursday Monthly Forecast raw hindcast data are generated. 1344 mofc_thu_refc_pp At this stage, the Thursday Monthly Forecast post-processed hindcast products have been generated. 285 mofcrefc At this stage, the Thursday Monthly Forecast hindcast products have been updated.
The above events have been replaced by two new events:
4300 ext00h1104 At this stage, the Extended Ensemble Forecast products have been updated. 4301 ext00h1104ref At this stage, the Extended Ensemble reforecast products have been updated.
We will not migrate the user's TC-1 jobs subscribing to the ENS Extended (mofc) events. Users will have to adapt their existing jobs and submit them to either of the two new ENS extended events. See command 'ecaccess-job-submit'.
ENS extended events
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:
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
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).
- Please remember to use the MSJ_ 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.
ENS re-forecasts.
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.
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_BASETIME=00 MSJ_DAY=22 MSJ_EVENT=ext00h1104ref MSJ_EXPVER=0078 MSJ_IFS_CYCLE=48r1 MSJ_MEMBERS=10 MSJ_MONTH=05 MSJ_STEP=1104 MSJ_YEAR=2023
