  Daily relative distributionof the user observations (green/yellow/red – good/average/bad).The continuous polyline, supported with a dotted trend line, indicates the daily average with higher readings representing poorer air quality (scale on the right; good=0, average=1 and bad=2).

  Citizen perception ofair quality • Piloted by Shenzhen University students – Over 1200 observations in Nov–Dec 2013 – Air quality perceived generally good in the morning and worse in the afternoon – Initial analysis shows correlation between citizen observations and small particle measurements Distribution of the majority of user observations in the central Shenzhen area

  Case: Algae bloom •Smartphone application that enables citizen participation in monitoring waters. Application is used to observe the occurrence and volume of cyanobacterium and kelp. Observations are shared with other users immediately on a map and stored for later analysis. • Pictures can be taken to help verify the observations later on. Citizen observations are used in combination with official algae observations in creating a situational picture of algae blooming, in algae control and in water quality research.
