40 -__**Data processing**__
41 -
42 -* Calculation of (weekly, monthly and/or Annually) mean levels of NO2, PM10 and PM2.5 at each sampling location as the average value of the all the measurements done before and after of the interventions. Comparison of mean values for NBS intervention and control sample locations in the implementation area.
43 -* Data comparison before and after of the intervention using the reference to assess possible meteorological or other factors influence
44 -* Calculations must be done using comparable periods of time before and after the interventions (i.e., if measurement period before of the intervention goes from nov18-oct19, measurement period must be at minimum from nov19- oct21 and processing can be done for either years or Annually).
45 -* For this KPI, continuous records of air quality are available and, therefore, a different processing of the information will be applied to evaluate the impact of the NBS
46 -
47 -__**Results**__
48 -
49 -* The calculated values will be compared qualitatively and quantitatively for the periods before and after the interventions in the NBS and reference sections.
50 -* [[image:1642531878696-957.png]]
51 -* Positive or null NO2, PM10 and PM2.5 impact values indicates negative or no impact of the NBS on PM concentration for that implementation. Negative values indicates a positive impact of that NBS on NO2, PM10 and PM2.5 concentration.
52 -* The additional methodology (using continuous data) aims to find significant differences by comparing the normalized distributions of the difference between the sections with NBS and the reference sections.
53 -* First, the normalized distribution of the difference of the hourly values of the NBS location and the reference location is calculated. Then, the distributions of data before and after of the interventions are compared. If significant differences are found between the distributions before and after the implementation, then the impact of the NBS can be assessed.
54 -* If the centers of the histograms of both distributions (before and after the implementation) are separated by more than the sum of the standard deviations, σ (i.e., 2σ), then they will be considered as significantly different (with a 95% probability). If the center of the histogram of the situation after the implementation is lower than that of the previous situation (and the differences are significant) then it will be concluded that the impact of the NBS is appreciable. As an equation, this statement could be presented as follows:
