Paper Abstract

This research uses the case study of methane characterization in order to explore more generally the design of remote sensing systems in response to specific environmental questions, and the integration of space based measurements with those of other platforms. In particular, this analysis examines the potential contributions of space based instruments to one of the most important objectives of a methane characterization program: a better understanding of the spatial behavior of sources. Due to its long atmospheric lifetime and relatively homogeneous distribution, any methane signal to be detected through remote sensing is small. The methane attributes of interest are not directly observable, but must be inferred through inversion of the spatially (and perhaps spectrally), integrated signal received by the instrument. This investigation explores the extent to which methane characterization is limited by uncertainty on the temperature profile, the water profile, surface albedo, and instrument noise. The capabilities of anticipated NASA Earth Observing System instruments in the context of various system configurations will be discussed.
