Making UM dumps

[simon.tett]

I would like to make atmosphere and ocean dumps for the UM at vn4.5. Are there any tools that do that? If so what are they?

thanks

Hi Simon,

I'm not sure what you're asking here. The UM will output dumps and they can be reconfigured from other dumps. We can provide dumps from the Met Office for specific recent dates and in GRIB format from ECMWF further back. What do you want to do to the dumps?

There's no CMS-maintained tool set for this (at vn4.5), but Robin may have some bespoke utilities. What is the data source for making the dumps?

Hi Willie,

I want to run about 120 different forecast cases using different variations of HadAM3 to test an idea. So I need a way of generating start dumps for the model. I am planning to use ERA-INTERIM. I am planning this as a student project…

Hi Simon,

I can create GRIB files based on ERA-Interim. You just reconfigure them using the UM to get the start dump. I've not tried this with UM4.5.

So is that 120 start dumps or just one start dump for 120 models?

Hi Willie & Grenville,

I think this is an issue where it would help to have a chat. Could I have a phone chat with one or both of you? Any time that works for you is probably OK for me.

thanks

Simon Wilson has some ERA data in grib which has been made available to SimonT - I believe progress can be made now making dumps.
