Regridding MODIS FPAR and LAI data #115

I (Dale) am attempting to run CMAQv5.2 and need gridded FPAR and LAI data.

I am attempting to Regrid MODIS FPAR and LAI Data following the tutorial:

https://github.com/USEPA/CMAQ/blob/5.2/DOCS/Tutorials/CMAQ_DustInput.md

However, I am getting the following error message:

discover35/discover/nobackup/djallen4/wrf/WPS> ./geogrid.exe
Parsed 26 entries in GEOGRID.TBL
Processing domain 1 of 1
ERROR: Could not open /discover/nobackup/djallen4/wrf/WPS/data/WPS_GEOG/modis_landuse_20class_30s/index

I do see a similar file in a subdirectory that ends with ... with_lakes
discover32/discover/nobackup/djallen4/wrf/WPS/data/WPS_GEOG/modis_landuse_20class_30s_with_lakes> ls -la index
-rw-r--r-- 1 djallen4 s1090 358 Apr 5 2017 index

Can this be fixed by modifying GEOGRID.TBL?

Here is the namelist I used.

!!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!
! The default datasets used to produce the HGT_M, GREENFRAC,

We have removed the dependency on additional input files with gridded FPAR and LAI data in CMAQv5.3. Information on using the dust module in CMAQv5.3 is provided in Chapter 6 of our new User's Guide.

If you have additional questions or issues, please post them on the CMAS User Forum: https://forum.cmascenter.org/
