  • The Greenland Flow Distortion EXperiment investigates the role of Greenland in defining the structure and the predictability of both local and downstream weather systems, through a programme of aircraft-based observation and numerical modelling. The Greenland Flow Distortion Experiment (GFDex) will provide some of the first detailed in situ observations of the intense atmospheric forcing events that are thought to be important in modifying the ocean in this area (but are presently poorly understood): namely tip jets, barrier winds and mesoscale cyclones. The dataset contains Met Office forecast products.

  • Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) is a Natural Environment Research Council (NERC) and Antarctic Funding Initiative (AFI) funded project, aimed at studying the chemistry of the Antarctic Boundary Layer in greater detail, and for a longer duration, than has previously been attempted. Field measurements were carried out at the British Antarctic Survey station, Halley, at the Clean Air Sector Laboratory (CASLab). Year-round measurements began in February 2004, and a summer campaign focussing on oxidants ran during January/February 2005, after which CHABLIS fieldwork ended. The dataset contains toal peroxy radical measurements during the CHABLIS summer intensive at Halley. Access to this dataset is now public.

  • The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains vertical column measurements of H2O, HDO, N2O, CH4, O3, HF, HCl, ClONO2, HNO3, CFC-11 and CFC-12 from BOMEM-DA2 ground-based experiment.

  • The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains vertical column measurements of NO2, O3 and OClO.

  • CCMVal was a large international effort to improve understanding of Chemistry-Climate Models (CCMs) and their underlying GCMs (General Circulation Models) through process-oriented evaluation, along with discussion and coordinated analysis of science results. The first round of CCMVal (CCMVal-1) evaluated only a limited set of key processes in the CCMs, focusing mainly on dynamics and transport. This dataset contains UMSLIMCAT model output from the WMO 2006 REF2 experiment run by the University of Leeds.

  • Validation data for the IASI (Infrared Atmospheric Sounding Interferometer) satellite instrument. IASI was a moderate resolution (0.25cm^-1) Fourier Transform spectrometer which was scheduled for flight in 2002 on the European METOP satellite. IASI delivered vertical profiles of temperature and humidity data with a resolution of 1km. VIRTEM was an EU project to validate the instrumentation and retrieval methods to be used on IASI. This dataset contains Atmospheric profiles, Ozonesonde and Mircowave radiometer measurements.

  • The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains ground based measurements of column abundance of ozone.

  • The European Arctic Stratospheric Ozone Experiment is a European Commission (EC) measurement campaign undertaken in the Northern Hemisphere winter of 1991-92 to study ozone chemistry and dynamics. This dataset contains vertical column measurements of NO2, O4, H2O and O3.

  • In Autumn 1995, the Goddard Distributed Active Archive Center (GDAAC) compiled the Climatology Interdisciplinary Data Collection (CIDC) to facilitate interdisciplinary studies related to climate and global change. This data collection has been produced in collaboration with the Center for Earth Observing and Space Research (CEOSR), Institute for Computational Sciences and Informatics (CSI), and George Mason University. It was designed for the study of global change, seasonal to interannual climate change, and other phenomena that require from one to dozens of interacting parameters. This dataset contains biosphere, hydrology, surface temperature, ozone, greenhouse gases measurements.
