In situ measurements constraining the role of sulphate aerosols in mid-latitude ozone depletion

Article Abstract:

The relation between the atmospheric concentration of sulphate aerosols and ozone depletion at mid-latitude levels was investigated. In situ measurements of NO and NOy were performed along with aerosol surface area, namely O3 and ClO. All the measurements were conducted simultaneously at mid-latitudes in the lower stratosphere. Results show that the influence of aerosol reactions on active nitrogen is strongly dependent on the gas phase reaction rates.

Observation of stratospheric ozone depletion in rocket exhaust plumes

Article Abstract:

Research shows that stratospheric ozone concentrations above the earth in the vicinity of Titan IV rocket flights became severely impacted immediately after each launch. Ultraviolet absorption photometer equipment was used to measure the ozone depletion effects following rocket launches in May and Dec 1996. Ozone concentration measurements against ultraviolet activity are illustrated.

Effect of climate change relative to ozone depletion on UV exposure in subarctic lakes

Article Abstract:

The magnitude of previous variations in the underwater light regime of a lake at the boreal tree line was estimated using fossil diatom assemblages together with bio-optical models.
