The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) OXIdising Capacity of the Ocean Atmosphere (OXICOA) Ozone Profile Experiment 96 (OZPROF-96) Aberystwyth Ozone Profiles Data from Ozonesonde and Ozone DIAL LIDAR contains tropospheric ozone data from balloon-launched ozonesondes and ground-based Ozone DIAL LIDAR in 1996. On 12 July 1996, an ozonesonde was launched ahead of a warm front into a clear sky. It encountered a layer about 1 km deep between 11 km and 12 km altitude where ozone concentrations reached values too low to be measured by the sonde (i.e. less than 3 ppbv).

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) was a 5-year Natural Environment Research Council (NERC) programme on tropospheric chemistry coordinated by the University of East Anglia and involving research groups from a number of UK universities and research institutes. The project had three consortia of UK institutes and universities, each of which focused on a different scientific topic. OXICOA (OXIdising Capacity of the Ocean Atmosphere) was a study of oxidant, radical and related gas-phase chemistry in the clean and moderately polluted marine atmosphere. The Eastern Atlantic Spring/Summer Experiments (EASE 96 and EASE 97) were carried to collect data. The dataset includes measurements of the OH and HO2 radicals, measurements of halogen oxide radicals at Mace Head in conjunction with a survey of potential organic halogen source gases. In EASE 96 the Cranfield Jetstream aircraft was deployed to measure the vertical and horizontal homogeneity of the air mass.

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) OXIdising Capacity of the Ocean Atmosphere (OXICOA) Eastern Atlantic Spring/Summer Experiment in 1996 (EASE-96) Centre for Atmospheric Science, University of Cambridge (CAS) Trajectory Model Data contains outputs of back trajectory model. The model used historic forecasts from European Centre for Medium-Range Weather Forecasts (ECMWF) to understand the origin and transportation of various atmospheric chemical species measured at he Mace Head Atmospheric Research Centre.

This data set is comprised of observations from Cranfield Jetstream Research Aircraft which carried three NOy monitors, an ozone monitor, a solarimeter, a gas chromatograph-flame ionisation detector and a temperature sensor off the eastern coast of Ireland to measure the vertical and horizontal homogeneity of the air mass for EASE-96.

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) OXIdising Capacity of the Ocean Atmosphere (OXICOA) Ozone Profile Experiment 97 (OZPROF-96) Aberystwyth Ozone Profiles Data from Ozonesonde and Ozone DIAL LIDAR contains tropospheric ozone data from balloon-launched ozonesondes and ground-based Ozone DIAL LIDAR in 1997.

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) OXIdising Capacity of the Ocean Atmosphere (OXICOA) Ozone Profile Experiment 97 (OZPROF-96) Aberystwyth Ozone Profiles Data from Ozonesonde and Ozone DIAL LIDAR contains tropospheric ozone data from balloon-launched ozonesodes and ground-based Ozone DIAL LIDAR in 1998. The level of ozone at high altitude on 6 December, 1998 was too low to be measured by the ozonesonde.

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Marine Aerosol and Gas Exchange (MAGE) Eastern Atlantic Experiment 96 (EAE-96) Shipborne Atmospheric Oxidants Data from on-board the RRS Challenger contains observations of various gases and aerosols off the western coast of Ireland in May 1997. The data were collected to understand properties of DMS, gases and aerosols in marine boundary layer conditions.

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Marine Aerosol and Gas Exchange (MAGE) Eastern Atlantic Experiment 96 (EAE-96) Airborne Atmospheric Oxidants Data from on-board Cranfield Jetstream Research Aircraft contains measurements of ozone, hydrocarbons and dimethyl sulphide (DMS) taken in summer 1996. The data were collected to understand the properties of of DMS, gases and aerosols in marine boundary layer conditions.

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Marine Aerosol and Gas Exchange (MAGE) Eastern Atlantic Experiment 96 (EAE-96) Airborne Atmospheric Oxidants Data from on-board Cranfield Jetstream Research Aircraft contains measurements of ozone, nitrogen oxides (NOx) and halocarbons taken during a two day flight in May, 1997. The data were collected to understand the properties of DMS, gases and aerosols in marine boundary layer conditions.
