ctgproc.inp

• NDBF – Set to 1 (we only have one input land-use file).
• LUDAT – Set to e.g. lulc1km_masaya.dat. This is the main output file containing the land-use categories on the intended CALPUFF grid.
• RUNLST – Set to e.g. ctgproc_masaya.lst.
• Subgroup (0b) – At the end of this section, ensure that there is only one line that reads "! GLAZNA = data/nalulcl20.bil ! !END!". This is the path to the land-use data file.
• MESHGLAZ – Set to 2 (1km res) or 11 (100m res). This will e.g. split each 1km input grid cell into 2x2 grid cells (each assigned the same land-use category). This ensures that there will be no 1km-res CALPUFF grid cells with missing data in them.
• PMAP – Set to ‘UTM’
• IUTMZN – Set to 16
• DATUM – Set to ‘WGS-84’
• XREFKM – Set to 525.09417
• YREFKM – Set to 1294.23926
• NX – Set to 91 (1km res) or 901 (100m res)
• NY – Set to 55 (1km res) or 541 (100m res)
• DGRIDKM – Set to 1.0 (1km res) or 0.1 (100m res)
