  • Temperature measurements were made between 2004 and 2005. The work was carried out at the Clean Air Sector Laboratory (Halley, Antarctica) as part of the CHABLIS project (2001-2006).

  • Radiosonde data were collected on and around the Antarctic Peninsula during the NERC-funded Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project. Atmospheric conditions on the upwind (western) and downwind (eastern) sides of the mountains were measured using these balloon-borne radiosondes released from a camp on Larsen Ice shelf camp and Rothera base. 24 radiosondes were launched from the Larsen Ice Shelf camp during the period 8-31 January 2011.

  • Weather Research and Forecasting (WRF) model output for Larsen Ice Shelf run at 4km resolution. Modelling was carried out to support the Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project during the 2010-2011 field season.

  • UK Met Office UM (Unified Model) output for Larsen Ice Shelf, run at 1.5km resolution. Modelling was carried out to support the Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project during the 2010-2011 field season.

  • Weather Research and Forecasting (WRF) model output for Larsen Ice Shelf, run at 1km resolution. Modelling was carried out to support the Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project during the 2010-2011 field season.

  • UK Met Office UM (Unified Model) output for Larsen Ice Shelf, run at 4km resolution. Modelling was carried out to support the Orographic Flows and the Climate of the Antarctic Peninsula (OFCAP) project during the 2010-2011 field season.

  • Meteorological data were collected between Jan and Oct 2005 from a sensor positioned on top of the FAGE container. The dataset lists temperature (degrees C), relative humidity (%), pressure (mB), wind speed (ms-1) and wind direction (degrees). Data were collected at averaged one-minute intervals. This work was carried out at Halley Station, as part of the Chemistry of the Antarctic Boundary Layer and the Interface with Snow (CHABLIS) project (2001-2006).

  • Data was collected via Automatic Weather Station (AWS), an ADAS tether sonde system, some radiosondes, a sensor and logger attached to the ice-crystal replicator system and an Ice Nucleus chamber. The collection was made during a month-long period in January and February, 2002, at a site east of Weatherheaven.The data are documented with a detailed diary, a summary of weather observation and a summary of data collection dates and hours.

  • Meteorological data acquired by Automatic Weather Station (AWS) located in the region of subglacial Lake Ellsworth. Data recorded includes wind speed, wind direction, temperature, pressure, humidity, and solar radiation.

  • The Skiymet meteor radar was deployed at Rothera (68S, 68W) in Feb 2005. The radar measures the winds, waves and tides of the mesosphere and lower thermosphere (MLT) regions of the atmosphere. The radar routinely makes three types of measurement: 1. horizontal winds at heights of ~ 75 - 105 km from the drifting of meteors as they are carried by the winds of the MLT; 2. atmospheric temperature from the decay rate of meteor echoes; 3. meteor fluxes, derived from several thousand meteors per day. The radar has been used with an existing, identical, radar in the Arctic at the conjugate latitude of 68N, 21E (Esrange) to produce accurate climatologies of winds, waves and tides - and to quantify the differences between the Antarctic and Arctic MLT (using identical radars eliminates otherwise problematic measurement biases). Other studies will carefully examine meteor/MF-radar instrument biases and apply a developing technique to continually measure temperature using the decay rate of meteor echoes. The radar complements the existing OH temperature spectrometer and imaging airglow camera at Rothera.
