A numerical radiative transfer model for a spherical planetary atmosphere: combined differential-integral approach involving the Picard iterative approximation
TL;DR: In this paper, a new radiative transfer model suitable to calculate the radiation field in a spherical planetary atmosphere has been developed, which involves the Picard iterative approximation to solve the radioregressive transfer equation in its integral form.

TL;DR: In this article, the ozone profile trends over the period 2000 to 2016 from several merged satellite ozone data sets and from ground-based data measured by four techniques at stations of the Network for the Detection of Atmospheric Composition Change indicate significant ozone increases in the upper stratosphere, between 35 and 48 km altitude (5 and 1 hPa).
Journal ArticleDOI
Combined differential‐integral approach for the radiation field computation in a spherical shell atmosphere: Nonlimb geometry
TL;DR: In this paper, a combined differential-integral approach (CDI) was developed, which is more accurate than commonly used pseudospherical models but not so complicated and computer time-consuming as a fully spherical model.
Journal ArticleDOI
Stratospheric Ozone Trends and Variability as Seen by SCIAMACHY from 2002 to 2012
Claus Gebhardt,Alexei Rozanov,Rene Hommel,Mark Weber,Heinrich Bovensmann,John P. Burrows,D. A. Degenstein,Lucien Froidevaux,Anne M. Thompson +8 more
TL;DR: In this article, the authors used a multivariate linear regression to calculate vertical profiles of the rate of linear change (trend) in the altitude range 15-50 km from decadal O3 time series obtained from SCIAMACHY1/ENVISAT2 measurements in limb-viewing geometry.
Journal ArticleDOI

Robert Loughman,E. Griffioen,Liisa Oikarinen,Oleg V. Postylyakov,Oleg V. Postylyakov,Alexei Rozanov,David E. Flittner,Didier F. Rault +7 more
TL;DR: In this paper, the authors compared the limb scattered radiances calculated by six radiative transfer models for a variety of viewing conditions, including molecular scattering, aerosol scattering, and ozone absorption.
