The Airborne Arctic Stratospheric Expedition II (AASE II) which was based in Bangor, Maine between October 1991 and March 1992, with ER-2 flights from Ames Research Center, Fairbanks (Alaska), and Bangor; and DC-8 flights from Ames, Bangor, Anchorage (Alaska), Stavanger (Norway), and Tahiti, was a follow-up to an earlier AASE campaign in 1989. The dataset consists of measurements collected onboard the NASA ER-2 and DC-8 aircraft (for example, ClO, BrO, HCl, O3, NOx, N2O, HNO3, whole air samples and aerosol measurements). In addition, there are ozonesonde soundings from six Canadian stations, global grid point values of Nimbus 7 TOMS ozone, and selected radiosonde soundings from stations in the region of the experiment. Theory teams provided calculations of potential vorticity, temperature, geopotential, horizontal winds, parcel back trajectories, and concentrations of short lived species along the aircraft flight tracks; and northern hemispheric analyses of potential vorticity, temperature, geopotential, horizontal winds, and radiative heating rates.

This dataset consists of MODEL data containing 12 Z hemispheric analyses of potential vorticity, temperature, horizontal winds, and radiative heating rates; and one file named MA911006.H00 which contains gas-phase chemistry model reconstructions of several radicals as a function of latitude, altitude, and local time.

The Cambridge Chemical Assimilation Data was produced as part of the Assimilation of Remote-sensed Data for Applications in the Atmospheric and Oceanographic Sciences (ARDAAOS) Natural Environment Research Council (NERC) thematic programme. It presents Chemical assimilation data from multiple sources, which is processed into a common file format making it easy to compare data from the various field campaigns and satellite missions.

The Airborne Antarctic Ozone Experiment (AAOE) aimed to study chemical composition and physical parameters in the Antarctic during the development of the Antarctic Ozone Hole in August and September 1987. The data is primarily that collected onboard the NASA ER-2 and DC-8 aircraft, along with ozonesonde data collected at four Antarctic stations: Halley Bay, McMurdo, Palmer Station, and the South Pole. The experiment tested the chemical and dynamical theories of the ozone hole using the aircraft data in theoretical computer models of the chemistry and dynamics of the stratosphere. The data include atmospheric composition, meteorological parameters, aerosol data and cloud data.

The GBS (Global Broadcast Service) dataset is a series of radio attenuation measurements made at three sites in the UK: Chilbolton and Sparsholt, both in southern UK, and Dundee in Scotland. The aim of the experiment was to make long term measurements of the signal strength received from a 20.7GHz beacon on the US Department of Defense satellite UFO-9 at multiple sites, in order to determine whether the use of site diversity as a fade mitigation technique would be effective. The dataset spans a period of 3 years, from August 2003 to August 2006 with signal attenuation sampled once per second. This dataset is cited in: S. A. Callaghan, J. Waight, J.L.Agnew, C. J. Walden, C.L.Wrench , S. Ventouras “The GBS dataset: measurements of satellite site diversity at 20.7 GHz in the UK”, Geoscience Data Journal, 17 March 2013, DOI: 10.1002/gdj3.2

Data were collected from the 1st of November 2006 to the 31st of October 2010 by the HALO photonics Doppler lidar at Chilbolton Observatory, Hampshire. The dataset contains measurements attenuated backscatter coefficients of aerosols within the atmosphere, as well as the radial and Doppler velocity of these particles. Plots of the attenuated backscatter coefficient at different heights, and of the Doppler velocity of particles are also available.
