Syntax:
OUTPUT MONTHLY [LATLON nnnHPA | ZONAL_AVERAGE]
Purpose: to define the output written to files. This output can be inspected after completion of the program by the plotting program written in IDL. Currently, global output fields can only be monthly averaged. Use STATION to define other output.
The concentrations are written in mixing ratio, but may be converted in the plotting program, e.g. to ppbv.
LATLON defines a concentration contourplot at a pressure level specified by nnnHPA, with nnn being 1000, or 900, ...., 100. The x-axis will be longitude (175W to 175E) and the y-axis will be latitude (85S to 85N)
ZONAL_AVERAGE defines a concentration contour plot with on the x-axis the latitude and on the y-axis the pressure.
To define monthly-averaged contourplots of the tracer concentration at three pressure levels:
OUTPUT MONTHLY LATLON 1000HPA
OUTPUT MONTHLY LATLON 500HPA
OUTPUT MONTHLY LATLON 200HPA
To define monthly mean, zonally averaged concentration plots:
OUTPUT MONTHLY ZONAL_AVERAGE
Default: no output.
