摘要:Abstract(#br)Production of oil and natural gas in North America is at an all-time high due to the development and use of horizontal drilling and hydraulic fracturing. Methane emissions associated with this industrial activity are a concern because of the contribution to climate r...

摘要:Abstract(#br)Polarimetry is one of the most promising types of remote sensing for improved characterization of atmospheric aerosol. Indeed, aerosol particles constitute a highly variable atmospheric component characterized by a large number of parameters describing particle ...

摘要:Abstract(#br)We present a general approach for the linearization of radiative transfer in a spherical planetary atmosphere. The approach is based on the forward-adjoint perturbation theory. In the first part we develop the theoretical background for a linearization of radiative t...

摘要:Abstract(#br)The computation of radiation transmittance in nongray, inhomogeneous atmospheric models is frequently complicated by complex bands of line spectra which range in value over many orders of magnitudes and depend strongly on either or both of pressure and temperature. W...

摘要:Abstract(#br)An accurate description of multiple scattering is essential in atmospheric radiative transfer modeling of ultraviolet and visible light in the Earth's atmosphere. Part of this multiply scattered radiation is inelastically scattered due to rotational Raman scattering ...

摘要:Abstract(#br)We present a linearization of pseudo-spherical vector radiative transfer using the forward-adjoint perturbation theory. The method, which is based on the usual forward and the adjoint formulation of radiative transfer, is extended to radiative transfer problems ...

摘要:Global measurements of atmospheric water vapour isotopologues aid to better understand the hydrological cycle and improve global circulation models.This paper presents a new data set of vertical column densities of H2O and HDO retrieved from short-wave infrared (2...

摘要:In light of the proposed space segment of Europe's future CO2 monitoring system, we investigate the spectral resolution of the CO2 spectrometer, which measures earthshine radiance in the three relevant spectral bands at 0.76, 1.61, and 2.06 ...
