Observing the impact of the Anthropocene on atmospheric composition using remote sensing from space based and aircraft instrumentation. — •John P. Burrows — Instiute of Environmental Physics, University of Bremen, Bremen

Since the industrial revolution, the earth's population has grown from 1 to ~7.5 Billion and at the same time its standard of living and longevity has increased dramatically. Pollution in the atmosphere now spans all scales from the local to the global. Air quality, stratospheric ozone and climate change are all being influenced by anthropogenic activity, and it is proposed that the earth has entered a new geological epoch the Anthropocene. The global measurement of many atmospheric trace constituents began with the SCIAMACHY (Scanning Imaging Absorption spectrometer for Atmospheric CHartographY) project in the 1980s. As a result of this initiative the following instruments have been developed and launched on satellite platforms into sun synchronous low earth orbit: GOME (Global Ozone Monitoring Experiment - ESA ERS-2 1995-2011), SCIAMACHY (ESA Envisat 2002 to 2012), GOME-2 (EUMTSAT Metop A 2006 to present, Metop B 2012 to present). In addition, the spin off OMI (Ozone Monitoring Instrument - NASA AURA 2004 to present) was developed by NSO. GOME GOME-2 and OMI make measurements of the back scattered electromagnetic up welling at the top of the atmosphere in nadir. SCIAMACHY makes alternate limb and nadir measurements. This presentation will provide an overview of the interpretation of the data provided by these instruments and related instruments developed for aircraft.
