Fresnel reflection amplitude coefficients (fractional amplitudes) at the surface of an isotropic, intrinsically nonmagnetic chiral medium are derived on the basis of the Drude – Condon model of optical activity. The eigenvalue – eigenvector solution is obtained with use of Berreman's 4 3 4 matrix method. Self-consistent results are obtained when the(More)
A new type of remote sensing radiometer based upon the Fabry-Perot interferometric technique has been developed at NASA's Goddard Space Flight Center and tested from both ground and aircraft platform. The sensor uses direct or reflected sunlight and has channels for measuring column concentration of carbon dioxide at 1570 nm, oxygen lines sensitive to(More)
1. ABSTRACT Global measurement of carbon dioxide column with the aim of discovering and quantifying unknown sources and sinks has been a high priority for the last decade. In order to uncover the " missing sink " that is responsible for the large discrepancies in the budget the critical precision for a measurement needs to be on the order of 3 ppm. That(More)
New type of remote sensing instrument based upon the Fabry-Perot interferometric technique has been developed at NASA's Goddard Space Flight Center. Fabry-Perot interferometry (FPI) is a well known, powerful spectroscopic technique and one of its many applications is to be used to measure greenhouse gases and also some harmful species in the atmosphere.(More)
