Global measurement of greenhouse gases and related air pollutants — •John P. Burrows — Institute of Environmental Physics and Remote Sensing, University of Bremen, Germany
In order to improve our understanding of the feedbacks within the earth atmosphere system, which determine the magnitude of global climate change, global measurement is required of greenhouse constituents at adequate spatial and temporal sampling scale. One of the holy grails of Earth Observation is the measurements of tropospheric constituents from space. In this context the determination of the loading of greenhouse gases such as Carbon Dioxide, CO2, and Methane, CH4, in the boundary layer and lower troposphere at a precision capable of testing our understanding of their sources and sinks is challenging. SCIAMACHY (the Scanning Imaging Absorption spectroMeter for Atmospheric CHartographY), which flies aboard ENVISAT is the first Earth Observation instrument to attempt this. It is the forerunner of the missions OCO (Orbiting Carbon Observatory, from NASA and GOSAT, Greenhouse gases Observing SATellite, from JAXA. This presentation will discuss the measurements of natural and anthropogenic greenhouse constituents and related pollutants from space.
