Regional and even global scale vegetation monitoring is possible using data from the AVHRR sensor. This instrument will remain the basic source of data for such studies over the next few years. Much research still needs to be done with regard to sensor calibration, development of atmospheric correction routines, and algorithms for the detection of sub-pixel clouds and cloud shadows, before quantitative study of global vegetation dynamics is possible. However, past work has shown that ecologically significant parameters, such as primary productivity, phenological development, surface temperatures and fire events, can all be measured with varying degrees of precision, and applied to key global environmental issues such as deforestation, desertification and atmospheric pollution.
