The European Arctic Stratospheric Ozone Experiment (EASOE) was undertaken in the northern winter of 1991-92 to study the processes in the Arctic which lead to ozone destruction and their connection with reduced ozone at northern mid-latitudes. The data from the campaign has been made available on CD-ROM by the Norwegian Institute for Air Research (NILU). The CDs are held at the BADC. This two CD-ROM set contains measurements made from 16 ground stations throughout Europe, flights made by the three aircraft involved in the campaign, numerous stratospheric balloons launched from Kiruna in northern Sweden and from ozonesondes from 28 European stations. In addition data from the total ozone monitoring network are included. The parameters measured include concentrations of ozone and the members of the chlorine and nitrogen families which are involved in the photochemical destruction of ozone, aerosol and PSC extinctions and meteorological parameters used to study transport into and out of the polar vortex. The EASOE campaign coincided with the NASA AASE-II aircraft campaign and this dataset is also available from the BADC.

This dataset contains wind, temperature and humidity measurements. Oxidant and Particle Photochemical Processes above a South-East Asian tropical rain forest (OP3-Danum-08) is a 3-year Consortium Grant of the Natural Environment Research Council (NERC), beginning 1 October 2007. The objectives of the OP3 project are (i) to understand how emissions of reactive trace gases from a tropical rain forest mediate the production and processing of oxidants and particles in the troposphere, and (ii) to better understand the impact of these processes on local, regional and global scale atmospheric composition, chemistry and climate.

Daily weather observations measured by students and staff at Halkali Agricultural School (a school opened in 1892 for agriculture and animal husbandry during the Ottoman period) from 1896 to 1917 in Istanbul, Turkey have been transcribed from the original publications into digital form and translated from Ottoman Turkish (the Perso-Arabic script) to English (Latin alphabet). Over 55 thousand observations of daily maximum, minimum and average temperature, rainfall, soil and under soil (0.25m) temperature, humidity, pressure, and wind speed were recovered.

Data from observations made at the Cape Verde Atmospheric Observatory (CVAO) which exists to advance understanding of climatically significant interactions between the atmosphere and ocean and to provide a regional focal point and long-term data. The observatory is based on Calhau Island of São Vicente, Cape Verde at 16.848N, 24.871W, in the tropical Eastern North Atlantic Ocean, a region which is data poor but plays a key role in atmosphere-ocean interactions of climate-related and biogeochemical parameters including greenhouse gases. It is an open-ocean site that is representative of a region likely to be sensitive to future climate change, and is minimally influenced by local effects and intermittent continental pollution. The dataset contains meteorological measurements (wind speed and wind direction) logged by the webDAQ and wind speed, wind direction, atmospheric pressure, air temperature, relative humidity, solar radiation, rainfall measured by instruments on the tower between 2006-2012.

The Antarctic Mesoscale Prediction System (AMPS) is an experimental, real-time numerical weather prediction capability that provides support for the United States Antarctic Program, Antarctic science, and international Antarctic efforts. AMPS produces numerical guidance from the Weather Research and Forecasting (WRF) model with twice-daily forecasts covering Antarctica. The effort is sponsored by the National Science Foundation (NSF) Office of Polar Programs and the NSF UCAR and Lower Atmospheric Facilities Oversight Section. It is a collaboration of the National Center for Atmospheric Research and the Byrd Polar Research Center of The Ohio State University.

The Weybourne Atmospheric Observatory (WAO) is a Regional station in the Global Atmosphere Watch (GAW) programme of the World Meteorological Organization (WMO). It is situated on the North Norfolk coast (52°57’02’’N, 1°07’19’’E, 15 m asl). The dataset collection contains meteorological data such as wind speed, wind direction, humidity, atmospheric pressure, solar irradiance and net irradiance, SoDAR wind profiler data, sonic anemometer data, and Chemistry data such as ozone, carbon monoxide and oxides of nitrogen gas chromatograms for measurements of VOC's and GHG's (Volatile Organic Compounds / Green-House Gases, respectively. In addition, cloud condensation nuclei measurements are available. Over the years the parameters measured at Weybourne have varied according to the funding and/or scientific interests and requirements. There have been continuous measurements of ozone, as part of the Defra network, and basic meteorological parameters. There are many years of CO, NOx, NOy, SO2, CN, VOC and H2 data. In 2007 a long term monitoring programme for CO2 and O2 began. In 2012 a new greenhouse gas GC was set up and measurements of CH4 started. This has been developed to also include measurements of N2O and SF6. In 2017 a state-of-the-art Fourier Transform Infrared Spectrometer (FTRI) was added to Weybourne to give very high precision measurements of additional CO2, CH4, N2O and CO. Through the introduction of the FTIR to Weybourne in 2017, the site now forms part of the UK’s commitment to the EU funded Integrated Carbon Observation System (ICOS). This is a pan-European Research Infrastructure that provides very high quality, harmonised data on the cycles of carbon and other greenhouse gases. Through ICOS Weybourne has been at the forefront of instrument testing and has been fundamental in getting the FTIR instrument approved on the network. As well as being the only UK atmospheric station within the ICOS network and part of the Defra ozone network (AURN), Weybourne has been / is part of the Defra TOMPS network (atmospheric toxic organic samplers), a Defra CH4 network, the EU InGOS network (Integrated non-CO2 Greenhouse gas Observing System) and is now contributing measurements to the NERC funded MOYA and DARE-UK projects.
