Las Cardas Experimental Station Coquimbo, ChileTest Site Information
Las Cardas Experimental Station site is located at the Southern border of the Atacama desert. The dominant vegetation type is a xerophytic steppe combining shrubs and a floor of annual herbs. The station covers 3500 ha. with experimental facilities owned by the University of Chile. The regional climate is arid subtropical steppe (mediterranean regime) with a short rainy winter ( 3 months). Annual temperature ranges between 28 and 5 C with a mean of 14.5 C. Average annual rainfall is 10 cm. The subtropical anticyclone influences climate, creating clear sky conditions for most of the year. Some of the ongoing research programs are:
Product Request for the Coquimbo GLCTS ProductGo to GLCTS Project ServerCoquimbo Header FileProject Description: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. Site Description:Las Cardas Experimental Station site is located at the Southern border of the Atacama desert, and is run by the University of Chile. The station covers 3500 ha. of xerophytic steppe, combining shrubs and annual herbs. Ongoing research programs include grassland management, ecosystem rehabilitation, modeling of primary production, ecophysiology, and desertification dynamics. Site researchers are also applying remote sensing and environmental information systems in their research. Data Format and Organization: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.
