Create variable aqiwdpm10

Process Step

Description Compute target variable ‘aqiwdpm10’ starting from variables ‘Concentration’ and ‘AirPollutant = PM10’ for each background station. Compute where ‘AirQualityStation’ has values for the pollutant. Find ‘Concentration’ value at the 99th percentile for the pollutant. Create EEA Air Quality Index where PM10: 0 to 20 eq ‘Good’ represented by value ‘0’; 20 to 40 eq ‘Fair’ represented by value ‘1’; 40 to 50 eq ‘Moderate’ represented by value ‘2’; 50 to 100 eq ‘Poor’ represented by value ‘3’; 100 to 150 eq ‘Very Poor’ represented by value ‘4’; 150 to 1200 eq ‘Extremely poor’ represented by value ‘5’. The worst air quality level measured on a specific date on one of the background stations in the region provides values to the variable.

This step uses a script written in Python3.
