Climate Forcing by Anthropogenic Aerosols
Although long considered to be of marginal importance to global climate change, tropospheric aerosol contributes substantially to radiative forcing, and anthropogenic sulfate aerosol in particularExpand

Thirty years of in situ stratospheric aerosol size distribution measurements from Laramie, Wyoming (41°N), using balloon‐borne instruments
[1] Vertical profiles of size-resolved aerosol concentrations above Laramie, Wyoming (41°N), have been measured for the past thirty years, 1971-2001. During this period, two somewhat differentExpand

Increase in background stratospheric aerosol observed with lidar at Mauna Loa Observatory and Boulder, Colorado - article no. L15808
The stratospheric aerosol layer has been monitored with lidars at Mauna Loa Observatory in Hawaii and Boulder in Colorado since 1975 and 2000, respectively. Following the Pinatubo volcanic eruptionExpand

The increase in stratospheric water vapor from balloonborne, frostpoint hygrometer measurements at Washington, D.C., and Boulder, Colorado
Stratospheric water vapor concentrations measured at two midlatltude locations in the northern hemisphere show water vapor amounts have increased at a rate of 1-1.5% yr'1 (0.05-0.07 ppmv yr"1) forExpand

The evolution of the dehydration in the Antarctic stratospheric vortex
In 1994 an intensive program of balloon-borne frost point measurements was performed at McMurdo, Antarctica. During this program a total of 19 frost point soundings was obtained between February 7Expand

Ozone destruction through heterogeneous chemistry following the eruption of El Chichón
It is now well established that heterogeneous reactions provide an important mechanism for Antarctic ozone depletion. Recent laboratory studies suggest that the same reactions that occur on HNO3/H2OExpand

The role of carbon dioxide in climate forcing from 1979 to 2004: introduction of the Annual Greenhouse Gas Index
High-precision measurements of CO2, CH4, N2O, CFC-12, CFC-11 (major greenhouse gases) and 10 minor halogenated gases from a globally distributed network of air sampling sites are used to calculateExpand

Stratospheric Aerosol Measurements III: Optical Model Calculations
Abstract : Articles in the literature dealing with light scattering properties of atmospheric aerosols are numerous and of great variety. Many fall into two general categories: those in which theExpand

A new look at atmospheric carbon dioxide
Abstract Carbon dioxide is increasing in the atmosphere and is of considerable concern in global climate change because of its greenhouse gas warming potential. The rate of increase has acceleratedExpand

Four decades of ozonesonde measurements over Antarctica
[1] Ozonesonde observations from Syowa and the South Pole over more than 40 years are described and intercompared. Observations from the two sites reveal remarkable agreement, supporting andExpand
