Arguments
calpuff_inp
the absolute path and filename for the working CALPUFF input file.
moz
the choice of ozone data input (ignored unless mchem is 1, 3, 4, 6, or 7): (0) use a monthly background ozone option, or (1) read hourly ozone concentrations from an OZONE.DAT file.
bcko3
monthly ozone concentrations as ppbV values (ignored unless mchem is 1, 3, 4, 6, or 7, and, moz is 0 or 1).
mnh3
the choice of ammonia data input (ignored unless mchem is 6 or 7): (0) use monthly background ammonia values, or (1) read hourly ammonia concentrations for each vertical layer from a NH3Z.DAT file.
mavgnh3
the choice of ammonia vertical averaging method (ignored unless mchem is 6 or 7, and, mnh3 is 1): (0) do not calculate averages and use NH3 at puff center height, or (1) average NH3 values over vertical extent of puff.
bcknh3
monthly ammonia concentrations as ppbV values (ignored unless mchem is 1 or 3, or, mchem is 6 or 7 and mnh3 is 0).
rnite1
the nighttime SO2 loss rate in percent per hour. This rate is used only at night for when mchem is set to 1. This rate is added to the computed rate both day and night when mchem is either 6 or 7 for heterogeneous reaction chemistry.
rnite2
the nighttime NOx loss rate in percent per hour (ignored unless mchem is set to 1).
rnite3
the nighttime HNO3 formation rate in percent per hour (ignored unless mchem is set to 1).
mh2o2
the choice of ammonia data input (ignored unless mchem is 6 or 7): (0) use a monthly background H2O2 option, or (1) read hourly H2O2 concentrations from an H2O2.DAT file.
bckh2o2
monthly H2O2 concentrations as ppbV values (ignored unless mchem is 1 and either mh2o2 is 0 or mh2o2 is 1 and all hourly H2O2 data is missing).
bckpmf
the average background fine particulate concentration, in units of ug/m3, for each month of the year (ignored unless mchem is 4 or 7).
ofrac
the average organic fraction of fine particulate matter for each month of the year (ignored unless mchem is 4 or 7).
vcnx
the average VOC to NOx ratio (after reaction) for each month of the year (ignored unless mchem is 4 or 7).
