Stratospheric aerosol characteristics from space-borne observations: extinction coefficient and Ångström exponent

Toward a combined SAGE II-HALOE aerosol climatology: an evaluation of HALOE version 19 stratospheric aerosol extinction coefficient observations

Herein, the Halogen Occultation Experiment (HALOE) aerosol extinction coefficient data is evaluated in the low aerosol loading period after 1996 as the first necessary step in a process that will eventually allow the production of a combined HALOE/SAGE II (Stratospheric Aerosol and Gas Experiment) aerosol climatology of derived aerosol products including surface area density. Based on these ana...

Tropical stratospheric aerosol layer from CALIPSO lidar observations

Space-borne observations link

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract The causes of high tropospheric column ozone values over the Tropical Atlantic Ocean during September, October, and November (SON) are investigated by examining lightning during 1998–2001. The cause for high tropospheric column ozone in the hemisphere opp...

Improved stratospheric aerosol extinction profiles from SCIAMACHY: validation and sample results

Stratospheric aerosol extinction profiles have been retrieved from SCIAMACHY/Envisat measurements of limb-scattered solar radiation. The retrieval is an improved version of an algorithm presented earlier. The retrieved aerosol extinction profiles are compared to co-located aerosol profile measurements from the SAGE II solar occultation instrument at a wavelength of 525 nm. Comparisons were carr...

Retrieval of stratospheric aerosol size distribution from atmospheric extinction of solar radiation at two wavelengths.

The possibility of retrieving size distribution of aerosol particles in the stratosphere by measuring the extinction of solar radiation traversing the aerosol medium at two different wavelengths is explored in this work. This paper presents a parametric study of the effects of size distribution and composition of stratospheric aerosols on the value R, the ratio of extinction of solar radiation ...
