  6. 6. Atlantic Rainforest Micrometeorology Sensor Network in Brazil (University of São Paulo, Microsoft Research, Johns Hopkins University) Serra do Mar N S 50meters Towers(Images courtesy of Humberto Rocha, Rob Fatland, and Andreas Terzis)
  7. 7. SwissEx Put all data together for better understanding Share data with other scientistsTemperature Snow Soil Streams Humidity
  8. 8. Key Technical Challenges • Sensor networking • Energy management • Data yield improvements • Deployment strategy • Data management • Data interoperability • Data archival • Sensor tasking • Data visualization • Temporal-spatial indexing • Online aggregation and representation
  9. 9. Participatory Environmental Monitoring Toolkit  Objectives • Facilitate socially inclusive environmental observation o Time & GPS location o Temperature & Humidity o CO2 o H2S • Leverage existing Microsoft technologies and user communities • Deliver a HW+SW toolkit in open source form  Key technologies • Microsoft Research low energy GPS location sensing and mobile data collection services • OData • World Wide Telescope(WWT) • Windows Azure
  10. 10. Sense Web: The Wikipedia of sensors Real-time indexing, aggregation, and tasking.
  11. 11. Cypress: Data Stream Compression• Compress data to reduce storage and I/O cost• Answer queries directly on compressed data• 100X compression typical sensor data streams • Take advantage of data types. • Trim data based on sufficient precision.Columns • Spectrum analysis – store data based on frequency bands • Store anomalies separatelyTrickles • Use sketches to compress “noise” – preserve data correlation. • Find correlations among data streams.GAMPS: • Store data as differences or ratios to reference streams.
  12. 12. Open Data Sharing Popular Software Packages* Factors Influencing Technology Adoption* The Lowest Common Denominator OData • Easy of use • Additional value SQL • Professional technical support*Cyberinfrastructure for the waters networks: a Survey of AEESP and CUSHAI Members, K.A. Lawrence et al, May 2006,
  13. 13. WWT and Geo-Data VisualizationWorldWide Telescope (WWT)• A visualization software environment • Enables a computer to function as a virtual telescope • (astronomers call it “the best VO (virtual observatory) implementation”) • Visualizes geo-data in 4D (space + time) • Integrated with Excel • Allows data sharing with controlled access – WWT Community • Empowers high-quality, intuitive, and interactive visual presentation via “WWT tour”• Datasets under consideration • Seismic event distribution against sbuductionslab slab models (USGS NEIC) • Standardized-format datasets (OGC, WxS, NetCDF, Shapefile, CSV, HDF, …) • Dataset and model output concept: plugging data generators directly into WWT • Draped raster, e.g. MODIS ocean, land and atmospheric products • Alternatice topgraphy, e.g. ice sheet thickness and bathymetry • Climate change thematic datasets, e.g. monthly sea ice extent from NSIDC• Free for research and education use
  14. 14. WWT and Dust Storm Simulation• A mutually beneficial case study • Mind-swap, e.g. at Open Data for Open Science Developers Training • Improve science modeling • Improve computer engineering
  15. 15. Wikipedia of Environmental Sensing• Open platform, open data• Free participation• Discoverable, searchable, interoperable• Visualized, annotated, built on top of each other
  16. 16. Microsoft Environmental InformaticsSince 2010• Vision: facilitate seamless access to environmental data and information• Focus: data discoverability, accessibility, and consumability• Objectives: • advance the technology use in environmental research • create design wins using Microsoft technologies to • Foster innovations in computational environmental research • Advance interoperability of data and information sharing • Facilitate citizen science for environmental research• Build a community among multiple disciplines and stakeholders
