1 GOFC/GOLD - Fire Requirements for Fire Observations

2 Requirements and Status

3

4 Fire Observations Near Real Time (15 mins) for Regional Fire Control and Air Quality Management Temporal Summaries for Fire and Ecosystem Management, National Reporting and Global Change Research Requirements for –sensing systems with appropriate characteristics for deriving fire products –Intermediate and derived fire products of known accuracy –Web based open access to data –Consistent Long Term Data records – fire history and policy effectiveness Requirements evolving - user needs / observation capabilities –Rapid operational prototyping

5 Summary Requirements: Active Fire/Fire Power Integrated Multi-source Satellite acquisition with appropriate sensors for fire detection (SWIR, MIR, Thermal – geolocation, spectral and temporal registration) –15 minute Geostationary Global Geostationary Network –Daily Day/Night Polar Orbiting Moderate Resolution (500m-1km) –Targeted High Resolution (<30m) Imaging (24 hours) e.g. Sensor Web Derived Products (Validated) –NRT Active Fire - Location /Power/Detection Probability (mins to hours) –Daily, Monthly, Annual, Multiyear Active Fire Distributions Web based fire location delivery (inc. alert system)

6 Summary Requirements: Burned Area Multi-source Satellite Acquisition with sensor characteristics for burned area estimation (geolocation, band to band registration, visible, NIR, SWIR) –Daily Geostationary <1km –Daily Polar Orbiting Mod Resn (250m - 1km) –Targeted High Resn (30m) E.g. sensor web technology – link to active fire detection Derived Validated Products –NRT ( Hrs) High (30m) and Moderate Resn (250 – 1km) Burned Area identification –Global day Moderate Resn Burned Area, Seasonal, Annual Summaries, Multiyear record –30m Burned Area (Post fire assessment and Validation) – targeted fires

7 Summary Requirements: Fire Emissions Satellite Data –15 min Geostationary (Active fire / Area Burned / Smoke) for NRT –Global Daily observations (Burned area products) for temporal summaries In-situ Data (Sample) –Fuel Load for product validation –Emission Factors –Aerosol optical thickness (e.g. Aeronet) Intermediate Product –Modeled Fuel Loads – seasonal / annual Derived Products (Modeled) –NRT Trace Gas and Particulate Emissions –10/16 Day – Monthly Emissions, Seasonal summaries, Multi annual emissions –Direct emission observation – aerosols, trace gases

8 Summary Requirements: Fire Danger Status Satellite Data with appropriate characteristics for monitoring vegetation state (geolocation, registration, vis, nir, swir, thermal) –Polar Orbiter 250-1km (vegetation state, moisture content) In-situ Data –Weather –Fuel amount and condition (satellite and modeled) Intermediate Products –Recent Weather (Assimilated) –Satellite Vegetation Moisture Content –Modeled Fuel amount (Allocated annual NPP) Derived Products (Modeled) –10/16 Day – Fire Danger Rating

9 Importance of Product Validation Importance of providing products of known accuracy (validated products) for both science and applications Validated to Stage 2 prior to broad distribution - range of conditions for which the product is provided GOFC/GOLD close partnership with CEOS Cal Val WG -Land Products Validation (LPV) –International coordination needed for Stage 3 Global Product Validation

10 GOFC/GOLD-Fire Goals Increase user awareness –develop an increased understanding of the utility of satellite fire products and their use for global change research, resource management and policy (UN, Regional, National, Local) Establish a geostationary global fire network –providing operational high temporal resolution standard fire products of known accuracy Secure operational polar orbiters with adequate fire monitoring capability –providing operational moderate resolution long-term global fire products to meet user requirements and serving a network of distributed ground stations –providing improved fire products (fuel moisture content/active fire/burned area/fire characterization) in a timely fashion –Providing operational high resolution acquisition allowing active fire, burned area, fire characterization and post-fire assessments

11 GOFC/GOLD-Fire Goals (Contd) Determine product accuracies –operational network of fire validation sites and protocols established providing accuracy assessment for operational products and a test bed for new or enhanced products – leading to standard products of known accuracy Develop a set of standard fire danger / susceptibility models –combining meteorological data, remote sensing, and ground based information Develop fire emissions product suites –providing annual emission estimates of known accuracy with the associated input data Establish enhanced user products and data access – Operational multi-source fire / GIS products, Web based data access, Improved national fire reporting, Fire characterization Promote experimental fire observation systems and related research –in new areas focused on meeting current information gaps
