Tmpbeis4 uses version 4 of the BEIS model. Tmpbeis4 reads the gridded, normalized emissions file BEIS4_NORM_EMIS and meteorological data from MET_FILE1 and optionally MET_FILE2 (these files may be either MET_CRO_2D or MET_CRO_3D). Note that Tmpbeis4 uses temperature and surface pressure data that must be in MET_FILE1, and radiation/cloud data that may be in MET_FILE1 or MET_FILE2. Within Tmpbeis4, speciation profiles are used to speciate biogenic pollutants for appropriate chemical mechanisms. Various speciation profiles for the CB6, and SAPRC mechanisms are available for BEIS modeling. The normalized emissions and meteorological data are used to produce gridded, speciated, hourly biogenic emissions. Additionally, an optional seasonal switch file, BIOSEASON, can be used to determine when and where to use summer or winter normalized emissions data on a daily basis.
