-The "Compare Atmosphere Data"-script analyses and compares two user defined locations in the same simulation for a specified variable. The idea of the the script is, that two areas in the same simulation are directly comparable. The script output shows 2 plots, each with two figures. The fist plot shows the mean, maximum and minimum values for each timestep at location A in the upper figure and at location B in the lower figure. The second plot shows the direct comparison between both locations: The upper figure shows the mean values of location A and B and the lower figure shows the absolute difference between the mean values for each timestep. +The "Compare Locations"-script analyses and compares two user defined locations in the same simulation for a specified variable.

Anyway, if you leave the Diagram Title field empty the script generates a appropriate title automatically. +In addition you can also define a diagram-title which will be used in the output figure.

 Note that the execution-time of the script may be unexpected high, especially when you compare longer time periods or large areas. This is caused by limited implementation options caused by the Delphi-Python-interface. During execution, the GUI might not be reactive. Note that the execution-time of the script may be unexpected high, especially when you compare longer time periods or large areas.
