…issions are scaled from CO (specified in HEMCO_Config.rc). Contains biome-specific H2 emission factors for biomass burning calculations using GFED4. The emission factors come from Akagi et al., (2011) and Andrae (2019). It considers H2 dry deposition velocity external fields from Yashiro et al. (2011) for which HEMCO is used as input file reader by using the HcoState ‘HCO_EvalFld’ subroutines. As implemented, the code will work if a scale factor to the dry deposition velocity fields is specified, this is done by HCO_EvalFld subroutine.

…des a 1% production of H2 to available aldehydes (ALD2, HPALD, MACR, MGLY, RCHCO) - MACR and MGLY are special cases, for which the H2 channels are specified separately. MGLY and MACR have the abs. cross sections without the qy. The H2 reaction is separated from the pressure-dependandt channels used currently for MGLY for the traditional photochemical channel.
