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 GUSTO: Robust Timely Decision Making (Generic Ultraviolet Sensors Technologies & Observations) Wireless connectivity GUSTO unit 1 HTTP, SOAP, GSI Sensor registry & control service SensorML Single Pollutant Contour Mapping HTTP, SOAP, GSI Warehouse GUSTO unit 2 Data access service Data upload service Monitoring and control software Public access Web visualizer Archived weather data High Throughput Discovery Informatics Data – Retrieved (pollutant) concentration values from atmospheric absorption spectra Multiple Pollutant Concentrations shown by bar charts Highly Polluted Area Archived health data GUSTO unit 3 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 add-on
