FIELD SPECTROSCOPY AND CAL/VAL ACTIVITIES

FIELD SPECTROSCOPY AND CAL/VAL ACTIVITIES

 

Hyperspectral remote sensing plays a primary role in Earth observations, as it enables better quantifying of important bio- and geophysical parameters and the monitoring of Earth’s dynamic processes. In support of future satellite missions, airborne and field spectroscopy measurements are fundamental, offering valuable data to consolidate the technical components of various instruments, algorithm prototyping and better understanding of the link between optical signals, parameters and processes at different observational scales

The last decade has experienced unprecedented expansion in the area of automatic field spectroradiometers for unattended (unsupervised) measurement of vegetation through experimental use of various instruments and configurations. The main goal of these activities is to develop efficient and multi-scale system sampling systems for monitoring the optical properies of the ecosystems (i.e. reflected and emitted domains).
