Generate UM start dump

I wondered if anyone has any scripts that will take a start dump from the CAM or CCSM model and extract and convert the prognostic variables needed to start the UM?

Hi Alex,

Do you need to start from these dump types specifically, or do you just need a start dump? I can get start dumps from the Met Office up to five years and from ECMWF. Just let me know the dates you need.

Hi Willie,

We are trying to do a run of the climate in the Permian (ca 200 Ma). I don't think that ERA goes back that far… We have been given a start dump from a study using CCSM3 a model developed by NCAR. It would be great if someone could help us out with how to go about converting this to initialise the UM!

Hi Alex,

I'm no expert on this, but if your data is in netCDF format you could use the Iris package ( to read it in and then output it in GRIB format. You can then reconfigure to get a UM start dump.
