Ambient Environmental Sensor Network
Assessment of Noise and Air Quality at a high spatial
resolution;
Aims:-
High resolution sensor network and data collection service
Quantification of population exposure to pollutants
Production of data sets that will enhance decision making processes in
relation to environmental management & improvement of quality of life
Identification and making linkages with sources of pollutants
Encourage citizen engagement and feedback
Making real time data available to the citizens to inform
and modify behaviour
Mapping of pollution concentration levels in Dublin
Assist in research

Ambient Sound Monitoring Network
•To measure outdoor ambient sound levels in the City
•To validate Sound Modelling Outputs
•Fulfils commitment in the Noise Action Plan
•To be able to assess impact of specific events immediately
•To measure diurnal variations over time.
Why Monitor ?

Challenges Facing Deployment of Sensors
Finding Suitable locations that include: -
• Power
• Representative of area being sampled
• No dominant source
• Sensors require to be inexpensive
• Ability to calibrate system
• Able to communicate remotely
• Secure & reliable data storage

35. Traffic Noise & Air Quality Unit

Challenges re Data Handling
•How data is to be presented
•Decide whether to release raw or calibrated data
•How to quality control the data
•How to ensure data is accurate
•How to ensure data is readily accessible.
•How to make information easily understandable
