GEOSS and Metrological Support for MeasuringM Radiometric Properties of Objects of Observations GEOSS Requirements • High quality of data • Global scale observations • No spatial or temporal gaps in the data • Accumulating real time data over decades 8
GEOSS and Metrological Support for MeasuringM Radiometric Properties of Objects of Observations Formulation of the problem - 1 Optical sensors present a major part of the GEOSS program. • Providing imaging data • Measurements of radiance, reflective properties, and radiation temperature of observation objects. Measurements can be trusted only if the instruments are metrologically robust. The task of the universal use of data acquired with the GEOSS subsystems can be solved only on the basis of common standards (data formats, geolocation, etc.). • For a number of applications such as climatology, meteorology, and a environmental monitoring, assuring the uniformity of radiometric measurements obtained by all subsystems and at an unusually high accuracy and stability levels is of extreme importance. • These exact requirements have not yet been properly reflected in the 10-yr plan. • The solution of the problem requires joint efforts both in supporting this idea and in implementing it at the international level. 9
