Collection of datasets from the European Space Agency's (ESA) Antarctic Ice Sheets Climate Change Initiative (CCI) project. This is producing long term and reliable climate data records from satellite data for a number of Essential Climate Variables (ECV's) for Antarctica. Current data products relate to Ice Velocities, Gravimetric Mass Balance, Grounding Line Locations and Surface Elevation Changes.

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. This dataset contains 4.5km numerical weather prediction data.

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 PAN (Peroxy-Acetyl-Nitrate) mixing ratio. Access to this dataset is now public.

This dataset includes a high-resolution gridded model hindcast simulation of the Antarctic Peninsula during the period 1998-2017, produced using the Met Office Unified Model (UM). Variables included in the dataset include near-surface meteorological variables like temperature and relative humidity, atmospheric profiles such as winds and humidity on pressure levels, cloud properties such as liquid/ice water paths, surface energy balance terms such as radiative and turbulent fluxes and surface fields such as surface meltwater production. All variables are outputted at 3- or 6-hourly intervals. Variables are separated into individual netCDF files, which are either two dimensional (for example surface for near-surface meteorological fields) or three dimensional (for example atmospheric profiles), over time. The region covered is the central and northern Antarctic Peninsula, centred on the Larsen C ice shelf. The simulations are gridded on rotated pole coordinates and cover the period 01-01-1998 00:00 UTC to31-12-2017 23:59 UTC. A dynamically downscaled regional (limited area) version of the UM is run in atmosphere-only mode at 4.0 km horizontal grid spacing, with 70 vertical levels and a 100 second time step for the inner domain. The model is re-initialised from ERA-Interim reanalysis data every 12 hours, and the time series is produced by concatenating the t+12 hour to t+24 hr segments of each integration into a continuous time series. Specifics of the model configurations and parameterisations used to produce the simulations are documented in Gilbert et al. (2020) (doi: 10.1002/qj.3753). These simulations were produced as part of the doctoral work of E. Gilbert, and was supported by the Natural Environment Research Council through the EnvEast Doctoral Training Partnership (grant number NE/L002582/1). E. Gilbert also acknowledges the use of the MONSooN system, a collaborative facility supplied under the Joint Weather and Climate Research Programme, a strategic partnership between the Met Office and the Natural Environment Research Council.

Ground-based meteorological data from Automatic weather stations (AWS) were collected to observe the atmospheric flow along a transect across the Antarctic Peninsula mountains around 67 degrees south during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project (2011). These AWS were located on the Avery Plateau, Cole Peninsula and North Adelaide Island.
