The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) OXIdising Capacity of the Ocean Atmosphere (OXICOA) Long-Term Studies of chemical Climatology (LTERM) is the longer term studies of the Eastern Atlantic Spring/Summer Experiments (EASE-96 and EASE-97). The longer term data includes DMS, ozone and chemicals involved in its cycle, carbon and hydrocarbons to help interpreting the data collected over the ACSOE campaign by providing insights on seasonal changes of chemicals.

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 FREETEX (Free Troposphere Experiment) campaigns as part of ACSOE-OXICOA were carried to collect data. The dataset includes measurements of ozone (O3, NOx, NOy, HNO3, PAN, CO, HO2 + RO2, HCHO, VOCs, etc.), at the Jungfraujoch High Alpine Research Station (3,580m above sea level) over a five-week period in 1996 and again in 1998.

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) OXIdising Capacity of the Ocean Atmosphere (OXICOA) was a study of oxidant, radical and related gas-phase chemistry in the clean and moderately polluted marine atmosphere. The objectives of Ozone Profile Experiment (OZPROF) was to obtain ozone profiles data which could be used to study the variations and structures of tropospheric ozone. This collection contains ozone profiles data obtained from Aberystwyth using ozonesondes and LIDAR for the period between 1996 and 1998.

The Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Marine Aerosol and Gas Exchange (MAGE) Eastern Atlantic Experiment (EAE) aimed to quantify input of Dimethyl sulphide (DMS) into a parcel of air, examine the oxidation of DMS and its reaction with nitrogen species with time, investigate the formation of new particles as a results of these transformations, and to discriminate between natural and anthropogenic fractions of sulphur and nitrogen using isotopic measurements. To meet these aims, numerous species of gases and aerosols in the marine boundary layer were measured on land from the Mace Head Research Station, on sea from the RSS Challenger and in the air from the Cranfield Jetstream Research Aircraft during two separate campaigns in 1996 and in 1997, and the observations are currently stored under this collection.

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 project had three consortia of UK institutes and universities, each of which focused on a different scientific topic. The Aerosol Characterisation Experiment (ACE) aim was to determine and understand the properties and controlling factors of aerosol in the anthropogenically modified atmosphere of the North Atlantic, and to assess their relevance to radiative forcing. The data was collected as part of the HILLCLOUD-96 and 98 experiments, where a hill cap cloud which forms over a ridge on the north east of the island of Tenerife was used as a natural flow through reactor. The dataset contains the size distribution, size dependent chemical composition and hygroscopic properties of the marine and modified continental aerosol arriving at the North coast of the island.

The Testing Atmospheric Chemistry in Anticyclone (TACIA) project as part of the ACSOE-OXICOA program was carried to collect data. The dataset was collected by the C-130 research aircraft; a former transport aircraft operated by the Meteorological Research Flight (MRF), and includes in situ trace gas photochemistry measurements.

The Meteorological Research Flight (MRF) was a Met Office facility, which flew a well-instrumented C-130 Hercules aircraft for atmospheric research purposes. This dataset contains airborne atmospheric and chemistry measurements taken on board the Met Office C-130 Hercules aircraft flight A480 for the ACSOE project.
