-# Python scripts for plotting with atm and grid output of MPTRAC
+# Python script  Examples 
+
+Here we provide some example Python scripts that can be used to plot MPTRAC output.
+
+## Plotting of atm and grid output of MPTRAC
 
 Call the python plot scripts with parameter <datadir> and <plotdir>
 
       python ./plot_atm.py ../example/data pythonplots
 
-## Library required
+Library required
 
 * scipy-stack
 * Cartopy
 
       sudo apt-get install python3-scipy python3-cartopy
+
+## Plotting of atm_select and met_map output of MPTRAC
+
+To plot the data created with atm_select call the python script atm_traj.py using Python3
+
+      python3 plot_traj.py
+
+Here, a single trajectory on a map is plotted from the datafile traj_5450.tab provided in the directory data. 
+
+To plot data created with met_map call the python script plot_met_map.py using Python3  
+
+      python3 plot_met_map.py
+
+Here, three parameters (O3, H2O and temperature) are plotted vs longitude and latitude from the datafile map_era5_2017010817_2_2.tab provided in the directory data.       
+
+The python libraries required to run these scripts are:
+
+* numpy
+* pandas
+* xarray
+* matplotlib
+* Basemap
