As part of the GA4.0 UKCA development, in Cambridge we are developing a N216L85 GA4.0 model using the CheT(+GLOMAP) configuration. However, there is no GA4.0 N216 base model existing at MetUM version 8.4.
Create a GA4.0 N216 Base model
There are a number of steps that need to be made before a base GA4.0 N216 model is ready for UKCA to be included:
- Assess the models available at the GA development page
- It is therefore necessary to regrid amche to N216 for use by UKCA
- There is a guide on how change the horizontal resolution on the GA twiki.
- The ancillary files can be taken from xhcea which already exist on MONSooN.
- There may be other changes that have been made between aliur and xhcea which are not represented in the guide. I have therefore asked Jeremy Walton to port aliur as well as amche over to MONSooN to check the differences.
- There is a guide on how change the horizontal resolution on the GA twiki.
