State-wise distribution of monitoring stations is shown in Figure 3.2. Since the target sampling of 24 hours in a day could not be fulfilled at all the locations due to power failures etc., the values monitored for 16 hours and more are considered as representative values for assessing the ambient air quality for a day. The target frequency of monitoring twice a week, 104 days in a year could not be met in some of the locations, in such cases 40 and more days of monitoring in a year is considered adequate for the 26 72 2 2 2 AP AR AS Bi CH CG DL DD GO GU HA HP JK JH KA KE MP MA ME MN MI NA OR PO PU RA SI TN TR UP UT WB States Figure 3.2: State-wise Distribution of Ambient Air Quality Monitoring Stations under N.A.M.P. 4 8 3 12 19 2 16 2 36 2 14
purpose of data analysis. The outliers from the data were removed. N.A.M.P. is being operated through various monitoring agencies, large number of personnel and equipment are involved in the sampling, chemical analyses, data reporting etc. It increases the probability of variation and personnel biases reflecting in the data, hence it is pertinent to mention that these data be treated as indicative rather than absolute. 73
