| Zusammenfassung |
| Carbon dioxide (CO2) plumes from non-erupting active volcanoes, power plants, and other
point source emitters are continuous but their plume characteristics differ due to individual
source strength, injection altitude, prevailing winds, local topography, time dependent
variability, and other factors. For example, power plant emissions vary by demand & load
cycles, while volcanic CO2 emissions follow less regular natural time dependent
oscillations. We investigate the best approach to detect, verify, and determine the flux of
CO2 emissions from power plant and volcanic point sources using space borne
infrared absorption spectra from NASA’s Orbiting Carbon Observatory 2 (OCO-2)
satellite.
Two polar orbiting sun-synchronous satellites currently measure atmospheric CO2 with
sufficient sensitivity and spatial resolution to detect point sources and their plumes: GOSAT
and OCO-2. GOSAT, launched in January 2009 by JAXA, provides 260 km spaced
single-sounding grid points at a 3-day repeat cycle with a circular field of view of 10km
diameter, at ~0.25/s samples. OCO-2 (leading the A-train on the CALIPSO ground track,
repeat cycle 16 days), launched in July 2014 by NASA continuously collects eight |
