Discovery Net in Action:
Air Pollution Modeling & Monitoring
Discovery Net is funded by the EPSRC under UK e-Science Program. GUSTO is funded by
EPSRC, NERC, Imperial College and industry. More information at www.gusto-systems.net

GRID Infrastructure
Visualisation and
Data Mining
(KDE)
Information – Real-time variations in concentration with (x,y,z,t) - leading
to imaging and mapping capabilities
Knowledge – Increased scientific understanding of pollution. Correlative
studies between local pollutant levels and related health effects and
weather records.
Benefits –e.g. re-routing of traffic, closure of schools, based on best
available knowledge.
•High throughput system Based on DUVAS technology (200270 nm)
Low Ambient Concentrations
•Measures SO2, NO, NO2,O3 & Benzene at ppb levels
simultaneously
•Robust algorithm for pollutant concentration retrievals
• Data storage using Grid infrastructure
• Globus Toolkit 3 (OGSA and OGSA-DAI)
• Grid Services for data upload and access
• Sensor authentication using GSI (X.509 certificates)
• Visualisation and data mining using Discovery Net
• Cross-correlation with external data sets, eg Health, Weather
•Geared for networking of multiple GUSTO units in a GRID
Infrastructure
•Multisource Remote Sensing data for (contour) mapping of
pollutants
•Upgrade path to CO, CO2 monitoring and correlation with IR
