2004-09-12 Data and Tools for Web-Based Monitoring and Analysis

  1. 1. Fire Related Data & Analysis www.DataFed.net : Data Sharing/Processing Infrastructure Integrated disparate data sources can provide new insight into the characteristics of fires and their air pollutant emissions. The DataFed infrastructure was used to integrate distributed fire related data sources and build analysis tools for comparing these datasets. Data Catalog and Access Dozens of datasets on aerosols, emissions, fire, meteorology, GIS Aerosol Datasets Software Tools Dozens of datasets on aerosols, emissions, fire, meteorology, GIS Data Federation (DataFed) is a web-based infrastructure for distributed data access and collaborative processing/analysis of air quality data DataFed Goals Facilitate the flow of atmospheric data from provider to users Support user-driven data processing value chains Participate in specific application projects Software for the Developer Software for registering distributed datasets to the data federation Web services for data access, processing and rendering Web service chaining for composing custom-designed data views   DataFed Technologies and Architecture Form-based, third-party wrapping of distributed data XML Web services for the execution of specific tasks Service Oriented  Architecture (SOA) for building loosely coupled application programs Data and Tools for Web-Based Monitoring and Analysis Center for Air Pollution Impact and Trend Analysis (CAPITA) Washington University in St. Louis AVHRR (red) and MODIS (blue) derived fire pixels during June 16-June23, 2004 Meteorological Datasets Interactive Data Browser FASTNET : Fast Aerosol Sensing Tools for Natural Event Tracking This Inter-RPO/NESCAUM pilot project characterizes the natural haze condition through detailed analysis of from forest fires, windblown dust and other sources. FASTNET datasets Over a dozen real-time and historical datasets are accessible to the community for the documentation of natural aerosol events. The data list includes satellite and surface data as well as models. Software tools The FASTNET software tools include web-based Analysts Consoles (collections of related data views shown on a single page), animation tools and special processing/display tools   Natural Aerosol Event Analyses The initial FASTNET project includes the detailed analysis of several historical (2000-2003) and current (2004) aerosol events.
