I’m running the Spatial Allocator program to make the spatial surrogates needed for SMOKE for a domain other than what EPA has been prepared. I have two problems:
- Although I need spatial surrogate codes 6831, 6832, and 6833, I couldn’t find the “surrogate specification” for the above-mentioned codes in the Spatial Allocator software.
- I found some spatial surrogates included in the EPA NEI platform, which have been gapfilled from ERG data. How can I gapfill those surrogate files using ERG data?
Your help is much appreciated.
