Meteorological data measured by the Meteorological Airborne Science INstrumentation (MASIN) onboard the British Antarctic Survey Twin Otter aircraft in the region of 67 degrees South on the Antarctic Peninsula during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project (2011).
The MASIN Twin Otter aircraft (VP-FAZ) fitted with atmospheric instruments flew 22 flight, lasting in total around 78 hours. During the intensive observing period from the 11th January to 5th February two strong westerly events took place (26-28th January and 4-5th February). Six flights were flown during the earlier event and five in the second. Easterly winds were experienced more often than westerlies and the remaining OFCAP flight were used to observe easterly flow events.
The flights normally consisted of an ascent on the west of the Peninsula, a transit across Peninsula at around 3000m altitude(often close to 67S - the line of AWSs but sometimes at 68S) and then a descent to the surface on the eastern side. In westerly event the aircraft would sample the detailed structure of the wind and temperature on the east of the Peninsula, while for easterly events more measurements were made on the west.
