Paper Abstract

Characteristics of tropospheric methane distribution and behavior relevant to an investigation of global climate change are discussed. Of several observational objectives, source characterization is identified as being particularly well suited to space-based measurement. Simple dispersion models are used to relate emission rates due to point sources and distributed sources to field of view and sensitivity of nadir-viewing instruments. Using these models in conjunction with instrument specifications, the contributions of the Tropospheric Radiometer for Atmospheric Chemistry and Environmental Research (TRACER) and the Tropospheric Emission Spectrometer (TES) are evaluated. General points related to methane observation are discussed, and future work is described.
