Hi,
I am not sure which model year are you running the CMAQ. Following things are what I usually do:
- ICBC:
a) from NOAA MOZART output
you can download MOZART output here, which is a global air quality model
MOZART Download
you can then convert these data into CMAQ IC/BC by mozart2cams, please see following link
b) if you can obtain GEOS chem data, you can convert these data into CMAQ format by
c) if you can obtain hemi domain CMAQ output you can create you IC BC by icon and bcon in PREP
- Inventory data:
EPA released all inventory data
ftp://newftp.epa.gov/air/emismod/
for example, this one includes all 2011 information that are SMOKE input ready
ftp://newftp.epa.gov/air/emismod/2011/v3platform/
However, most of these data are in 12US1 (12km) or larger (36km) resolution (some cases EPA released 4km surrogate files), if you would like to run for 1km you have to generate 1km surrogate files
Also EPA will release 2016 EMP CMAQ input ready data for 12US1 here

Hope this helps
