  • 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.

  • Marine Boundary Layer Ammonia and Nitrogen Dioxide Data from El Bailadero, Tenerife, Spain, designated as h2 or Site 2, collected as part of the HILLCLOUD-96 field campaign. The data were collected as part of the HILLCLOUD-96 experiment of the Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Programme's Aerosol Characterisation Experiment (ACE) project. The HILLCLOUD experiments utilised 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 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) 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.

  • 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).

  • Marine Boundary Layer Ammonia and Nitrogen Dioxide Data from Various Sites (categorised as hd) Tenerife, Spain collected as part of the HILLCLOUD-96 field campaign. The data were collected as part of the HILLCLOUD-96 experiment of the Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Programme's Aerosol Characterisation Experiment (ACE) project. The HILLCLOUD experiments utilised 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 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.

  • Marine Boundary Layer Ammonia and Nitrogen Dioxide Data from Taganana, Tenerife, Spain, designated as h1 or Site 1, collected as part of the HILLCLOUD-97 field campaign. The data were collected as part of the HILLCLOUD-97 experiment of the Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Programme's Aerosol Characterisation Experiment (ACE) project. The HILLCLOUD experiments utilised 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 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. The aims of the Marine Aerosol and Gas Exchange (MAGE) Eastern Atlantic Experiment were 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. Data contains profiles of aerosol size and distribution and trace gases throughout the marine boundary layer, taken using the British Aerospace Jetstream aircraft.

  • Marine Boundary Layer Ammonia and Nitrogen Dioxide Data from Punta del Hidalgo, Tenerife, Spain, designated as h0 or Site 0, collected as part of the HILLCLOUD-96 field campaign. The data were collected as part of the HILLCLOUD-96 experiment of the Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) Programme's Aerosol Characterisation Experiment (ACE) project. The HILLCLOUD experiments utilised 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.
