This post is somewhat relevant to a previous informative post regarding how to change the input (prescribed) SST data set:
http://forum.cgd.ucar.edu/showthread.php?1878-How-to-use-another-specified-SST-data&highlight=script
The information within the post linked above is useful if you are creating a new SST file that is on the same grid as a pre-existing quality checked SST data file. Perhaps one needs to to add anomalies or conduct an AMIP-type simulation. However, if I need to run a simulation where the grid of the new SST input file is different, then it is not clear how to deal with this issue given the provided scripts. Based on indications from the post linked above and the user's guide, it seems that creating a new compset is the best way to go.
For my situation, I would like to essentially run the F_2000_CAM5 compset at 0.9x1.25 degree resolution, with prescribed SST and sea-ice but an active land model and CAM5. However, my input SST data set (an thus sea-ice) is going to be 0.23x0.31 degree resolution. Thus, I need to generate interpolation files to add to the env_conf.xml script, namely:
1. MAP_A2OF_FILE
2. MAP_A2OS_FILE
3. MAP_O2AF_FILE
4. MAP_O2AS_FILE
5. MAP_A2LF_FILE
6. MAP_A2LS_FILE
7. MAP_L2AF_FILE
8. MAP_L2AS_FILE
9. MAP_R2O_FILE_R05
10. MAP_R2O_FILE_RX1
Files 1-4 I have created using the ESMF_RegridWeightGen by simply using the existing mapping files for 0.23x0.31 and 0.9x1.25 degree resolutions found in:
/glade/proj3/cseg/inputdata/share/scripgrids
Files 5-8 are set to "idmap" [identical map] because the CLM and CAM are on the same grid. At this point, my questions are:
- Is this sequence of steps correct, up to this point?
- How do I create the mapping files for MAP_R2O_FILE_R05 and MAP_R2O_FILE_RX1?
