Description

Can you get running on MONSooN the u-an979 suite for land surface modeling of an exoplanet?
Can you switch in a land surface and start playing with an easy way to setup flexible, idealised continents, and deal with the water cycle so that we can have pools and lakes?

The suite runs on MONSooN now. Still woriking on step#2.

comment:3 Changed 3 months ago by pmcguire

I have now switched in a land surface, as desired in step #2.

DETAILS:
The new thing I have done is followed the steps that Ian told me about in /home/d03/frib/ideal_land . This is running on MONSooN now as u-az020, and in a few hours we'll hopefully have land-only output to compare to the all-tiles version from u-an979 (my copy of u-an979 is u-aw657). This step has been done before by Ian et al., so this is mostly a check to see if things are working for me or not.

After some debugging with Ian Boutle, suite u-az020 works now for modeling a planet with just the bare soil land surface and no oceans (or vegetation). The changes outlined in /home/d03/frib/ideal_land can also be enabled by the OPTION='land' statement in the conf file alone. We also made a couple of other changes.

Neil Lewis has provided me some instructions for how to modify the Fortran code of the UM so that continents can be turned on or off.

Simon Wilson has given me some advice about how to work with land masks with the UM code. I have also been tutored by Benoit Vanniere about how to use xancil to convert a NETCDF land mask to a UM fields land mask.
