Biogenic GSPRO file

epenning · July 9, 2019, 6:49pm

I am configuring CMAQ with SAPRC07TB to calculate biogenic emissions inline, and am looking for a GSPRO file with the correct speciation codes. The GSPRO files provided as examples with CMAQ and SMOKE only apply to the carbon bond mechanism, I believe.

Thank you,
Elyse

Hi Elyse,
You need the B10SP profile. The gspro distributed with CMAQ should contain it:

USEPA/CMAQ/blob/5.3.b2/CCTM/src/biog/beis3/gspro_biogenics.txt

# Created 19 Mar 2009 by Chris Allen.
# Revised April 2017 for compatibility with CMAQv5.2
# This GSPRO component contains only biogenic profiles. The profiles were originally in
# the EMF dataset "gspro_static_cmaq", version 8 (16mar2009). They were moved to a 
# new dataset so that biogenic-only species do not appear in the model-ready files
# for non-biogenic sectors that have pre-speciated VOC in the inventory (specifically,
# 2005ck_05b othpt).
# This version is based on BEIS 3.6.1
#
# Definition of Fields:
# Mechanism Code 
#    Maps to BIOG_SPRO in the CMAQ run-script
#    Maps to SPNPRF inside CMAQ
#    Options -
#      B10C5: CB05-based mechanisms
#      B10C6: CB6r3-based mechanisms: ae6
#      B10C6AE7: CB6r3- ae7 based mechanism
#             1/8/2018 HOTP modified to split out APIN and not include in TERP 
#      B10RD: RACM2-based mechanisms
#      B10SP: SAPRC07t-based mechanisms (aero6 and aero7 compatible)

Starting with CMAQv5.3, the gspro profile is also determined by your version of aero (e.g. aero6 and aero7 with CB6 make different assumptions about monoterpenes).
