AO2018 took place in the Arctic from 1 August until 21 September 2018. These measurements were used to complement a suite of other observations taken during the expedition. Those of the UK contribution, as well as selected other data, are available within the associated data collection in the Centre for Environmental Data Analysis (CEDA) archives. Other cruise data may be available in the Bolin Centre for Climate Research MOCCHA/AO2018 holdings. These data consist of individual radiosonde profiles as 2D time/height fields, with all profiles interpolated onto a fixed vertical grid for ease of analysis/plotting. The vertical grid used is: 1m step to 5km, 10m step between 5 and 12 km, 50m step between 12 and 20 km. The data also includes derived variables (potential temperature etc). Humidity was corrected on profiles where the radiosonde selected the wrong (heated) humidity sensor. For some soundings the data file processing stopped too early, due to a loss of the GPS signal. Temperature and humidity data were recovered from the buffer files. Due to the loss of the GPS signal wind data are not available beyond the heights where the normal data files processing stopped. Radiosondes operated by Michael Tjernström, John Prytherch (University of Stockholm), Peggy Achtert (Uniersity Leipzig), Ian Brooks, Grace Porter and Mike Adams (University of Leeds).  Data processing performed by Jutta Vuellers (University of Leeds). These data are part of the ACAS project, funded by the Knut and Alice Wallenberg Foundation (Project PI Michael Tjernström). The sounding system was provided as part of the UK contribution to MOCCHA (UK project PI Ian Brooks) by the UK’s National Centre for Atmospheric Science (NCAS) Atmospheric Measurement Facility (AMF). NCAS AMF should be acknowledged in any publication making use of this data. Brooks, Ian M.
