This site located in a miombo woodland that undergoes some primitive harvesting for subsistence. The area is flat, and adjacent to the massive Zambezi River floodplain. Miombo-related species are about 16-18 meters tall, and grow in the Kalahari Sands. Kalahari woodlands cover approximately 6.3 million hectares in the Western Province of Zambia alone. The site is at the northern end of the IGBP Kalahari Transect, and has been associated with the AERONET (Aerosol Robotic Network) aerosol monitoring program for many years, including an intensive 1997 campaign. The AERONET network hardware consists of identical automatic sun-sky scanning spectral radiometers providing near real time observations of aerosol spectral optical depths, aerosol size distributions, and precipitable water. In 1998-1999, NASA-funded scientists will install an above-canopy tower at the site for semi-automatic and near-continous measurement of canopy level radiation properties. These will be augmented with ground transects and aircraft imagery. Additional atmospheric research is currently being proposed to study nutrient deposition.

The purpose of the Global LandCover Test Sites (GLCTS) project is to develop a multitemporal and multi-resolution satellite data set for a selection of global test sites to support the research development of land cover characterization and the testing and validation of improved algorithms for EOS. The sites selected represent a wide range of global land cover types, are well characterized on the ground with on-going field-based monitoring programs, and are of interest to the international global change research community. The primary component of the data set will be historical and recent Landsat data and a series of daily AVHRR 1km data acquisitions in a 500 Km by 500 Km window centered on the site. Digital elevation data and land cover information will be also included for each site.
As with all the Pathfinder projects, this activity will help provide experience with which to develop the data and information system for EOS. In particular, problems associated with developing registered multi-resolution and multi-source data sets, providing tools for data extraction, and developing the appropriate metadata and information management systems will be addressed. The targeted user-community for this product includes: researchers developing regional and global scale land cover assessments; researchers developing improved algorithm for surface parameterization; and field scientists working at the test sites wanting to explore the application of remote sensing.
The Mongu, Zambia site is at the northern end of the IGBP (International Geosphere/Biosphere Programme) Kalahari Transect and is being used by NASA-funded scientists as part of the validation activities for NASA's Earth Observing System. This site has been associated with AERONET aerosol monitoring program for many years. The site is located in miombo woodland that undergoes primitive harvesting for subsistence. An above-canopy tower at the site is to be installed by 1999 and these data will be augmented with ground transects and aircraft imagery.
Data are distributed on a series of low and high density 8 mm tapes, organized by data type. A copy of this header file is the first record on each tape and it will also include specific format and organization data for each tape.
