SAGE III Ozone Loss and Validation Experiment (SOLVE and SOLVE II)

The SAGE III Ozone Loss and Validation Experiment (SOLVE) was a measurement campaign in Kiruna, Sweden designed to examine the processes controlling ozone levels at mid- to high latitudes and to acquire correlative data needed to validate the Stratospheric Aerosol and Gas Experiment (SAGE) III satellite measurements used to quantitatively assess high-latitude ozone loss. The SOLVE campaign took place October of 1999 to March 2000, and SOLVE II took place November 2002 to February 2003.

The LARGE team made in situ aerosol and ozone measurements onboard the DC-8. We examined these data in conjunction with simultaneous measurements of meteorological parameters and trace chemical species to establish the aerosol spatial distribution in the lower stratosphere over the SOLVE study area and to determine the factors which control this distribution.

The above graphs show a time series of CN, SO2, surface area and mean mass diameter (over the 4 to 20000 nm diameter range) for a plume encounter on February 27, one day after the eruption of the Hekla Volcano caused a significant perturbation to lower stratospheric aerosol parameters.
