MODIS News
Mission
Global change research investigates the underlying processes of change and their manifestation,
the impacts and the prediction of change. Monitoring these changes provides an important underpinning to both
global change research and resource management. Monitoring of land cover and land use is an important element of
the NASA Earth Science Enterprise. Moderate resolution remote sensing provides a means for quantifying
land surface characteristics such as land cover type and extent, snow cover extent, surface temperature, leaf area
index, fire occurrence. Satellite measurements of leaf area, leaf duration and net primary productivity provide
important inputs to parameterize or validate ecosystem process models. High quality, consistent and well-calibrated
satellite measurements are needed if we are to detect and monitor changes and trends in these variables. Developing
the next-generation data sets for global change research is the challenge given to the MODIS Science Team.
The Moderate Resolution Imaging Spectroradiometer, or MODIS, sensor resides aboard the
Terra and Aqua platforms, offering a view the Earth's surface every 1-2 days. The MODIS sensor collects data within 36
spectral bands, ranging in wavelengths from 0.4 µm to 14.4 µm and provides us with imagery at a nominal resolution of
250 m at nadir for two bands, 500 m resolution for 5 bands, and the remaining 29 bands at 1 km.
