#22 fixed satellites and stash codes lois Caroline Bain
Description

Hello,

I have some questions about the UM I was hoping you could help me with:

  • is satellite data assimilated into the analysis and if so is cold cloud used to calculate real rainfall rates at all (I am interested in Africa of course!)?
  • I need to get out Vol SMC at critical point, there are two stash codes for this and neither work 00041 is not available and 08211 doesn't even show up on my diagnostics list. Any ideas?

Thanks, Caroline

#25 fixed setting size of STASH headers, pp0 (unit 60) cwang arbetter
Description

Hi,

In my job xcftf, I eventually get an error like

ERROR detected in routine STWORK: stop model : No. of output fields (= 4097 ) exceeds no. of reserved PP headers for unit 60 STASH : Error processing diagnostic section 15 , item 3 , code 4

STWORK : NO. OF FIELDS EXCEEDS RESERVED HEADERS

* UM ERROR (Model aborting) : Routine generating error: ST_DIAG1 Error code: 4 Error message:

STWORK : NO. OF FIELDS EXCEEDS RESERVED HEADERS

*

This appears to be a problem with saving to the xcftf.pp0 file (unit 60).

One way to avoid it might be to reduce the frequency in which data are saved to the file (which I can do in Atmosphere → STASH → Specification of Diagnostic Requirements).

But a more direct way would be to increase the number of reserved headers to something greater than 4096. Poking around the UMUI and some of the documentation, I haven't found where this can be done, though. Is it possible?

#26 fixed How is soil moisture analysed in UM? lois umdoc
Description

Hi there,

I was wondering how soil moisture was analysed in the UM? Is SM in the UM is changed according to weather station temp readings? If not, how does it change? Not through model rainfall I assume?

I just need to know if it relies on weather station analysis of air temperature or if it is purely diagnosed as a result of model moisture.

If there are any web sites to point me to, I'd be very grateful!

Thanks for your help,

Caroline
