Desertification Alters Regional Ecosystem Climate Interactions

ScienceDaily (January 27, 2005)

Using advanced remote-sensing techniques from a U-2 surveillance plane and field studies, scientists from the Carnegie Institution Department of Global Ecology have for the first time determined large-scale interactions between ecosystems and the climate during the process of desertification.

This image shows how spectral data, information contained in reflected light, obtained from the NASA Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) is organized into "data cubes. " It also shows what the reflecting light reveals as the sensor collects data from the canopy to the soil. The different types of vegetation are grasslands, transition areas, and desert shrublands in the Northern Chihuahua region of New Mexico. Credit : Image courtesy of Global Change Biology
