This dataset contains composite lidar wind profile data from the NCAS AMF Halo Doppler lidar mounted on a motion stabilised platform on board the Swedish Icebreaker Oden durning Arctic Cloud Summer Expedition (ACSE). ACSE took place in the Arctic during summer 2014. These measurements were used to complement a suite of other observations taken during the cruise. 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 NOAA ACSE and The Bolin Centre for Climate Research SWERUS (SWEdish-Russian-US) holdings - see online resources linked to this record. The Arctic Cloud Summer Expedition (ACSE) was a collaboration between the University of Leeds, the University of Stockholm, and NOAA-CIRES. ACSE aimed to study the response of Arctic boundary layer cloud to changes in surface conditions in the Arctic Ocean as a working package of the larger Swedish-Russian-US Investigation of Climate, Cryosphere and Carbon interaction (SWERUS-C3) Expedition in Summer 2014. This expedition was a core component to the overall SWERUS-C3 programme and was supported by the Swedish Polar Research Secretariat. ACSE took place during a 3-month cruise of the Swedish Icebreaker Oden from Tromso, Norway to Barrow, Alaska and back over the summer of 2014. During this cruise ACSE scientists measured surface turbulent exchange, boundary layer structure, and cloud properties. Many of the measurements used remote sensing approaches - radar, lidar, and microwave radiometers - to retrieve vertical profiles of the dynamic and microphysical properties of the lower atmosphere and cloud. The UK participation of ACSE was funded by the Natural Environment Research Council (NERC, grant: NE/K011820/1) and involved instrumentation from the Atmospheric Measurement Facility of the UK's National Centre for Atmospheric Science (NCAS AMF). This dataset collection contains data mainy from the UK contribution with some additional data from other institutes also archived to complement the suite of meteorological measurements.

The UK mean wind data contain the mean wind speed and direction, and the direction, speed and time of the maximum gust, all during 1 or more hours, ending at the stated time and date. The data were collected by observation stations operated by the Met Office across the UK and transmitted within the following message types: SYNOP, HCM, AWSHRLY, DLY3208, HWNDAUTO and HWND6910. The data spans from 1949 to 2018. This version supersedes the previous version of this dataset and a change log is available in the archive, and in the linked documentation for this record, detailing the differences between this version and the previous version. The change logs detail new, replaced and removed data. For further details on observing practice, including measurement accuracies for the message types, see relevant sections of the MIDAS User Guide linked from this record (e.g. section 3.3 details the wind network in the UK, section 5.5 covers wind measurements in general and section 4 details message type information). This dataset is part of the Midas-open dataset collection made available by the Met Office under the UK Open Government Licence, containing only UK mainland land surface observations owned or operated by the Met Office. It is a subset of the fuller, restricted Met Office Integrated Data Archive System (MIDAS) Land and Marine Surface Stations dataset, also available through the Centre for Environmental Data Analysis - see the related dataset section on this record.

Version 0 processing of data from the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar near Aberystwyth in West Wales represents processing scheme in place from the early 1990s until 2007. The principal measurements made by the MST radar are of the three dimensional wind vector over the altitude range 2 - 20 km, with additional measurements from the mesophere between 65 and 80 km. The data in this dataset include echo power as well as radial and vector winds components. Surface meteorological measurements from the radar site, ceilometer data, sky camera images and wind speed and direction recorded from a 10m tower located 6km away are also available. Other instruments at the facility have included one of the Met Office's boundary layer wind profilers and NCAS's boundary layer wind profiler.

Version 2 processing of data from the Natural Environment Research Council's (NERC) Mesosphere-Stratosphere-Troposphere (MST) Radar near Aberystwyth in West Wales. The principal measurements made by the MST radar are of the three dimensional wind vector over the altitude range 2 - 20 km, with additional measurements from the mesosphere between 65 and 80 km. These data include both the radial beam data plus the resulting Cartesian products. Surface meteorological measurements from the radar site, ceilometer data, sky camera images and wind speed and direction recorded from a 10m tower located 6km away are also available. Other instruments at the facility have included one of the Met Office's boundary layer wind profilers and NCAS's boundary layer wind profiler.

The wind profiler observations describe hourly observations from around 400 Wind profiler stations distributed globally. The observations cumulate in around 10,000 reports a day, giving measurements of parameters such as the different components of wind velocity, and the standard deviations of vertical and horizontal wind speeds. The data are collected by observation stations worldwide and transmitted within the WINPRO message. Wind speeds are given to the nearest metre per second. Air temperature is measured in Kelvin. Precipitation amount is given in kilograms per metre squared. Air pressure is given in Pascals. Relative humidity is measured as a percentage.

Meteorological data was collected by the University of Manchester at Langmuir ground station in the Magdalena Mountains, New Mexico, between July and August 2022 as part of the Deep Convective Microphysics Experiment (DCMEX) project. This dataset contains meteorological data from two ground meteorological stations. A Gill MaxiMet GMX600 meteorological station was installed at the Langmuir Laboratory main building (33.97495N, 107.18100W, ~3255 m) next to the Digitel aerosol filter sampler and provides measurements of wind speed, wind direction, temperature, humidity, pressure, and precipitation rate. A second meteorological station, a Vaisalla WTX536 meteorological station, was installed at the Langmuir Kiva-2 laboratory next to the Digitel aerosol filter sampler and provides measurements of wind speed, wind direction, temperature, humidity, pressure, and precipitation rate. The meteorological stations are supported by the University of Manchester scientists.
