satellites and stash codes

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?

Hello Caroline,

yes satelllite data is used in the UK Met Office data assimilation. There are various reports of what is used and its effect on the Met Office web site, for example
The question of whether you can use cold cloud to calculate real rainfall rates is much more complex according to the people I asked. The suggestion was that you should talk to people at TAMSAT
for more help in this matter.

As to your request of about volumetric soil moisture content, this is interesting. Firstly it was suggested that you look at the MOSES 2.2 technical document (Hadley Centre technical note 30) which is available from the UK Met Office site. If you are not using interactive vegetation then you should be able to get this from either the soil ancillary file or from the start file you are using, so 00041 is not applicable with fixed vegetation. The really interesting question is why is 08211 available with UM vn 4.5 but not UM vn6.1. I have checked the UK Met Office UMUI and it is not there either. It was suggested that this might be TRIFFID related but I will investigate this next year.

I hope that this goes some way to answering your questions although I am aware it doesn't really solve any of your real problems.
