Paper Abstract

Satellite thermal infrared (IR) spectral emissivity data have been shown to be significant for atmospheric research and monitoring the Earth’s environment. Long-term and large-scale observations needed for global monitoring and research can be supplied by satellite-based remote sensing. Presented here is the global surface IR emissivity data retrieved from the last 5 years of Infrared Atmospheric Sounding Interferometer (IASI) measurements observed from the MetOp-A satellite. Monthly mean surface properties (i.e., skin temperature Ts and emissivity spectra εν) with a spatial resolution of 0.5×0.5-degrees latitude-longitude are produced to monitor seasonal and inter-annual variations. We demonstrate that surface εν and Ts retrieved with IASI measurements can be used to assist in monitoring surface weather and surface climate change. Surface εν together with Ts from current and future operational satellites can be utilized as a means of long-term and large-scale monitoring of Earth’s surface weather environment and associated changes.
