The Jornada Long Term Ecological Research (LTER) site is maintained by New Mexico State University and is funded by the U.S. National Science Foundation. The Jornada Experimental Range is also designated as a Man and the Biosphere (MAB) Reserve, which allows comparative studies at other MAB Reserves in the Chihuahuan Desert at Big Bend National Park (Texas) and the Mapimi Biosphere Reserve in Mexico. The Jornada site lies within the Basin and Range physiographic province of the Southwestern United States. Throughout this region, soil development is strongly determined by topographic position, parent material, and climatic fluctuations during the Quaternary. The climate is characterized by abundant sunshine, wide diurnal ranges of temperature, low relative humidity, and extremely variable precipitation. Half of the precipitation at the site occurs in brief, localized, and intense convective thundershowers during July to September.
Field research at the Jornada LTER is conducted in various habitat types found within New Mexico State University's Chihuahuan Desert Rangeland Research Center (25,900 ha) and the adjacent lands of the USDA Jornada Experimental Range (78,266 ha). The Jornada LTER contains five major habitat types: black grama grassland (Bouteloua eriopoda), creosotebush scrub (Larrea tridentata), mesquite duneland (Prosopis glandulosa), tarbush shrublands (Flourensia cernua) and playa. Research at the Jornada focusses on changes in the distribution of soil resources as an index of the impact of desertification in semiarid lands, including studies of hydrology, primary production, nutrient availability and biodiversity.
The land cover map for the Jornada site was obtained from the New Mexico Resource Geographic Information System. The map is in UTM projection (zone 13, WGS84 datum) with upper left corner coordinates of 325600 north, 3607000 east and a pixel size of 30 meters. Additional land cover data is available through the New Mexico Resource Geographic Information System listed in the extended site description file.

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.

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.
The land cover map for the Jornada site was obtained from the New Mexico Resource
Geographic Information System. The map is in UTM projection (zone 13, WGS84 datum) with
upper left corner coordinates of 325600 north, 3607000 east and a pixel size of 30 meters.
