 === General advice ===
-  * Both scenarios should use the same meteorological conditions to keep the results compareable
+  * Only change one input parameter at once (e.g. for scenario 2: only change the meteorological conditions and keep the model area the same or do it the other way around). Thus, the results are still compareable.
   * The area of interest should exist in both scenarios.
   * The script output should be shown together with screenshots of both model areas (scenario 1 and scenario 2)

 Now the timespteps match again. Otherwise you would compare different timesteps.
+=== Advanced Settings ===
+There is the option to compare maximum or minimum values instead of the mean values. To do so, change lines 133 - 139 (in current script version) as follows:
+== Mean vallues (default) ==
+<code python>
+#vals1 = (np.nanmin(data1, axis=1), "Min.")
+#vals1 = (np.nanmax(data1, axis=1), "Max.")
+vals1 = (np.nanmean(data1, axis=1), "Mean")
+#vals2 = (np.nanmin(data2, axis=1), "Min.")
+#vals2 = (np.nanmax(data2, axis=1), "Max.")
+vals2 = (np.nanmean(data2, axis=1), "Mean")
+</code>
+== Maximum values ==
+<code python>
+#vals1 = (np.nanmin(data1, axis=1), "Min.")
+vals1 = (np.nanmax(data1, axis=1), "Max.")
+#vals1 = (np.nanmean(data1, axis=1), "Mean")
+#vals2 = (np.nanmin(data2, axis=1), "Min.")
+vals2 = (np.nanmax(data2, axis=1), "Max.")
+#vals2 = (np.nanmean(data2, axis=1), "Mean")
+</code>
+== Minimum values ==
+<code python>
+vals1 = (np.nanmin(data1, axis=1), "Min.")
+#vals1 = (np.nanmax(data1, axis=1), "Max.")
+#vals1 = (np.nanmean(data1, axis=1), "Mean")
+vals2 = (np.nanmin(data2, axis=1), "Min.")
+#vals2 = (np.nanmax(data2, axis=1), "Max.")
+#vals2 = (np.nanmean(data2, axis=1), "Mean")
+</code>
 === Output ===
 If all settings are done, the script is ready to get executed. The output should look like this:
-{{:apps:datastudio:compscenoutput.png}}
+{{:apps:datastudio:compscenoutput_atm.png}}
+If you would like to analyse pollutant-data instead, an output for e.g. NO2-concentration could look like this:
+{{:apps:datastudio:compscenoutput_polu.png}}
+==== Technical Note ====
+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.
