Data cluster 2.3. Urban environmental monitoring indicators
Last modified by Hyunji Cho on 2022/02/28 10:22
The urban environmental monitoring indicators have been selected to observe the impacts of DivAirCity interventions. Those indicators include both expected direct and indirect impacts.
| Indicators | Metrics |
| Air pollutant levels | Removal of atmospheric pollutants by vegetation |
| Change in air pollution - changes in concentrations in PM, NO2, O3, SO2 | |
| Air quality for diverse groups | Percentage of children ages 0 to 17 years living in neighbourhoods with pollutant concentrations above the levels of the current air quality standards (by race/ethnicity and by family income) |
| Percentage of days with good, moderate, or unhealthy air quality for children ages 0 to 17 years (by race/ethnicity and by family income) | |
| Concentration of particulate matter at respiration height along roadways and streets | The concentration of PM2.5 and PM10, respectively, per cubic metre of air (units μg m-3) at a measuring height of 1.5 m above the ground surface, or height of wheelchair users and children, to represent the air quality experienced by citizens |
| Avoided GHG emissions | The total amount of greenhouse gas emissions avoided as a result of implementation of NBS |
| Biodiversity | Number of species within defined area per Shannon Diversity Index |
| Carbon storage in vegetation and in soil | Increase of biomass in vegetation as tonnes of carbon stored |
| Common Air Quality Index | The two mandatory measurements for the ‘roadside’ CAQI are NO2 and PM10 (particulate matter less than or equal to 10 µm in diameter), with O3 also required for the ‘background’ index. The five qualitative categories that correspond to the index range from “very low” for values from 0 to 25 to “very high” for values that exceed 100. |
| Ecosystem Health and Integrity | Normalised Difference Vegetation index (NDVI): quantifies vegetation by measuring the difference between near-infrared and red light by using satellite images |
| Number of days in which air quality parameters exceed threshold values | Number of days in which air quality parameters exceed threshold values |
| Proportion of population exposed to ambient air pollution | Urban population exposed to air pollutant concentrations above EU standards and WHO air quality guidelines |
| Sustainable transport | Percentage of each mode of transportation (i.e. private, public, bicycles, pedestrians, availability of car-sharing solutions, availability of bicycles and eScooter renting services) |
| Rush hour periods / traffic density periods for key roads in and out of city | |
| Protection of water resource and environment | Total runoff volume |
| Water detention time |
