Tab::Line Plots

This tool plots the time dependent concentrations or other values of the saved variables (but see note at the end). If the variable is positive, you can also use logarithmic scale. If the variable has zero values and logarithmic scale is used, lowest values are omitted and the line is marked as dashed.

Load Box output file

Click this and select one of the General.nc, Chemistry.nc or Particles.nc files. The current plots, if any, are cleared from the panel. With very large chemistry or particle files the loading could take a couple of seconds. To make the inspection and summing of variables faster, the particle composition is calculated and stored in memory, but otherwise the values are read from the NetCDF file when needed. This means that the NetCDF file is kept open for reading as long as there are files loaded here. If you get NetCDF file I/O get errors at the end of the model run when the model from outside the GUI, check first that the output files were not opened here (In that case the output files will be found named *.tmp).

Add similar file

Available when at least one file is loaded, here you can add similar files (General → General, Particles → Particles etc.) from different runs. The legend will be picked from the NetCDF description "experiment" which is automatically written from the Date or Index, Group and run names.

Mixing ratios

Selections #, ppm, ppb, ppt selections are available when the unit of the inspected variable is #/cm3, and if General.nc was found from the same directory (the information to calculate air concentration is stored there). when particle phase mass is plotted, these options are unavailable and the unit is always ng/m³.

Filter

Like other similar occasions, by typing part of the name of a compound filters the list with matches of that text. Add a . (dot) after the name and the filter looks for that exact match.

Sum selection

With this option you can select multiple variables and sum them together. With Chemistry.nc and Particle.nc everything is in same units, so you can add any of the variables, but keep in mind that in General.nc the variables have different units and no unit conversion is made here (and anyway, what does temperature + pressure mean?).

Show particle phase concentarion

If the file(s) is Particle.nc, this option will show the total particle phase mass in ng/m3 for one or more compounds, if summed. This value is obtained by multiplying particle number concentration in each bin with mass composition in each bin, then summing over all bins.

NOTE that there are still some variables which cannot be viewed with these tools. For full list of saved variables, use ncdump or similar. For example to see the variables in Particles.nc, use the following (-h stands for header):

ncdump -h Particles.nc
