Resumen:
New detector technology has matured in recent yearsand now allows an instrument to be built which can measureatmospheric trace species and temperature from orbit withunprecedented three-dimensional spatial resolution. Theability of such an infrared limb imager to resolve gravitywaves (GWs) is assessed in a study sponsored by theEuropean Space Agency (ESA) and the following questionsare addressed: * can high-resolution temperaturemeasurements be processed to infer GW momentum flux? *how does the validity or otherwise of WKB and polarizationrelations affect such calculations? * how does the spatialobserving geometry influence: — the separation of GWsfrom the global background — GW amplitudes, horizontaland vertical wavelengths * which waves are visible to theinstrument We assess these questions by end-to-endsimulations of measurements and GW products. Thepotential of a new mission to measure GWs using infraredlimb imaging will be summarized based on thesesimulations, and compared to existing GW-measurementtechniques, such as satellite, ground-based and in-situ.
