Start Dumps

Reported by: avanni Owned by: willie
Component: Data Keywords:
Cc: Platform: MONSooN
UM Version: <select version>



I need to initialise my runs from UM analyses run with UM version 8.5 with GA6.

I would like to be able to do this for the entire month of January and the last day of December from the previous year (of any year that is available for this model version). I ideally need to re-initialise every 24 hours.
If it is possible to retrieve this data at 6 hourly resolution that would be perfect.

Do you know where I can get this data from? I am currently running the UM on monsoon, is there some way of retrieving this from MASS?

Hi Annelize,

What dates do you need? The MASS data gets thinned out, so data every six hours will only be available for the past six months. Older dates might have only one dump per day. For these, if six hourly is required we can build GRIB start dumps from ECMWF operational deterministic forecast data. If you don;t have a MASS account I can get the data for you.

Hi Annelize,

It looks like 31/Dec/14 hrs=0,6,12,18 and Jan 2015 for these same hours are available. This is 128 dumps each of 28GB, so the total is 3.5TB. It will take 64 hours on MONSooN to get this, but I may have to do it in 3 hour chunks due to restrictions on the queue length.

Hi Willie,

Thanks for getting back to me and apologies for not replying sooner but Stuart Webster is now helping me with this.
