 ### 2.2 Correlation with wind and temperature (analysis)
+- explore correlation between meteorological paramters to observed PM<sub>2.5<sub> concentration such wind, temperature, height above ground
+- capture espisode and examine relevant inputs with PM<sub>2.5</sub>
+- some examples from this exercise
