Global Observation of Forest Cover (GOFC)

                        Dr. Frank J. Ahern, CCRS
GOFC has already had an impact. In response to concerns raised by GOFC that a serious gap in L-band data is likely to occur between the end of the JERS-1 mission (likely 1998-2000) and the beginning of the ALOS mission (planned for 2003), STA/NASDA has promised to operate JERS-1 for as long as possible, hopefully until 2002 or 2003, and to launch ADEOS-II and ALOS in 2000 and 2003 respectively, to increase the availability of optical and L-band SAR data for GOFC objectives.
In addition, NASA has indicated its intention to target research and analysis funds for analysis of EOS and Landsat data to support GOFC objectives and participate in the constitution of a coordinated global forest cover data set. NASA plans include several sensors providing observations of forest cover as called for by GOFC, including Landsat-7, EO-1, Lightsar, and the Vegetation Canopy Lidar mission. EUMETSAT has set up a working group with the Joint Research Centre to determine what land products could beneficially be developed for routine processing from Meteosat Second Generation, the next generation of geosynchronous weather satellites.
1998 is the design year for GOFC, and we are currently in the midst of the design phase. We began 1998 with a meeting in Washington, D.C. to plan the design phase. At that meeting we created five design teams, each with specific tasks to accom-plish. Each design team is co-chaired by two or more persons who have been very active in continental to global scale projects dealing with forests. Most of the co-chairs have also been active in the development of GOFC to date. The design teams, their co-chairs, and tasks are shown in following Table.

Since the December meeting the design teams have been formed and most have met to address their tasks. In September the Design Team co-chairs will meet for an End-to-End Design Review to integrate their plans. The objective will be to draft a GOFC Design document, which can be refined for wide circulation, which clearly states GOFC objectives (with emphasis on deliverable products), and identifies priority activity areas to achieve these objectives.
Forest fires have been a serious problem in many parts of the world from late 1997 until now (August, 1998). Earth-observation data have played an essential role in monitoring these fires and the resulting smoke plumes. The public has been provided unprecedented access to E-O data on many websites dealing with various aspects of the forest fire problem. Several organizations have proposed projects to improve the information content and timely availability of E-O data of forest fires. In cooperation with the IGOS Disaster Management Project, GOFC will address the problems of the production and distribution of polar-orbiting meteoro-logical satellite data for forest fire detection and monitoring.GOFC expects to identify the mapping of burned areas as a high priority area where additional international cooperation can make a major contribution toward providing essential information in a timely, consistent manner around the globe.
During 1998, we have made contact with organizations which need various kinds of information about forests, to let them know about GOFC, establish linkages, and obtain a better understanding of their information requirements. Among these are the Biological Diversity Convention Secretariat, the Canadian Interagency Forest Fire Commission, the International Institute for Sustainable Development, the World Resources Institute, and the North American Forest Commission. Invited presentations about GOFC and its relationship to IGOS and CEOS have been made at the First International Conference on Geospatial Information in Agriculture and Forestry in Lake Buena Vista, Florida, and the 27th International Symposium on Remote Sensing of Environment in Tromso, Norway.

 ture (see Figure on page 1), and processes within an IGOS, he con-cluded that "an IGOS must provide the framework that will enable suppliers to be able to respond to (user) requirements. It must involve processes that will determine deficiencies, enable resources to be garnered to remedy such and be capable of improving not only the observational assets but also the various stages by which observations are turned into useful products. Finally, there must be a process by which the products and observations are monitored and analysed to ensure they are fulfilling their goals."
Dr. Brent Smith, NOAA, discussed "The Emerging IGOS Partnership," detailing ongoing efforts to broaden IGOS through convergence of the complementary efforts of CEOS and the Global Observing Systems and their Sponsors. He reported on the first such IGOS Partners Meeting convened the previous Saturday (June 6) in Paris at which participants had endorsed the IGOS initiative and agreed on a common Annex outlining overall principles, objectives and activities, with cooperation to follow on the basis of synergy among existing efforts.
Two of the six IGOS prototype projects were addressed by their leaders. The Disaster Management Support Project was presented by Helen Wood in a separate session. Dr. Frank Ahern, CCRS, discussed the Global Observation of Forest Cover (GOFC) Project; Dr. Philippe Courtier, CNES, addressed the Global Ocean Data Assimilation Experiment (GODAE) Project. Dr. Ahern outlined the need for a coordinated approach to providing global forest cover data sets to address global concerns, particularly about biodiversity, land cover degradation, and greenhouse gas buildup in the Earth's atmosphere. As an illustration of GODAE, Dr. Courtier focused in particular on Mercator, a project initiated by the French oceanographic community to develop an eddy resolving data assimilation system for the ocean.
