We clearly see an unusual pattern of number of records recorded by monitors 3, 4, 5, 6 and 9. The Above screenshots shows that the unusual pattern was mainly due to the chemical AGOC – 3A. The monitors are taking multiple reading where they are not supposed to be. Looking the graphs whenever there are higher number of records noted by monitors for chemical AGOC -3A, there are lower number of records recorded for chemical Methylosmolene which means monitors are confusing the AGOC – 3A chemical with Methylosmolene. This unusual pattern is shown throughout the year for all months. This can be verified by looking at the number of records for other two chemicals Appluimonia & Chlorodinine. For these two the number of records are almost constant throughout the year.

This unusual pattern was shown for monitors 7 & 8 also for the month of April which later got fixed in August & December.

Monitor 3 & 6 shows unusual pattern in readings as well. For all the 3 months, monitors 3 & 6 are showing extremely high readings. The same pattern was observed for monitor 4 as well but for the month of December only. We can conclude that In the month of December the wind direction was towards north west where the monitor 4 exists and hence the reading was more in monitor 4 specifically.
