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.

Radiosonde data measured using balloon-borne radiosondes released from the Larsen Ice Shelf Camp and Rothera Base on the Antarctic Peninsula during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project in January 2011.

Ground-based Automatic weather station (AWS), Radiosonde and British Antarctic Survey (BAS) Masin twin-otter aircraft data collected on and around the Antarctic Peninsula during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project. The OFCAP project conducted an integrated programme of field observations, analysis and modelling aimed at understanding of how the westerly winds interact with the mountains of the Antarctic Peninsula and how those interactions control the climate of the eastern side of the Peninsula. This dataset comprises of data from the month-long intensive field campaign which took place in January 2011. During this period, atmospheric flow along a transect across the Antarctic Peninsula mountains around 67 degrees south was observed using the British Antarctic Survey (BAS) MASIN- Twin-otter instrumented aircraft and automatic weather stations at Avery Plateau, Cole Peninsula and North Adelaide Island along the line of the transect. Atmospheric conditions on the upwind (western) and downwind (eastern) sides of the mountains were measured using balloon-borne radiosondes were released from the Larsen Ice shelf camp and Rothera base. These observations were then analysed in conjunction with the results of high-resolution atmospheric model simulations in order to obtain a more complete picture of the flow across the Peninsula. OFCAP was funded by the Natural Environment Research Council (NERC) for three years from Sept 2009 (NERC Reference: NE/G014124/1)
