  • Climate data have been collected at Scott Base continuously since 1957 and more recently from Arrival Heights and is one of the longest continuous climate records in Antarctica. Climate parameters measured include: wind speed and direction, air temperature, relative humidity, barometric pressure, and global, diffuse and direct solar radiation. Climate data are collected on a daily basis from both sites. At Scott Base, this takes two forms: a standard daily observation at 0900 NZDT, and continuous data collection at 10 minute and hourly intervals using a CR10X data logger. The initial record of the 0900 daily observations began on 1 March 1957 with air temperature, air pressure, wind speed and direction, and global solar radiation being measured with standard instrumentation (wind measurements since 1972). This record constitutes the reference record. In January 1997 an electronic weather station (EWS) was added to collect and archive 10 minute and hourly data. The daily manual observations continued so as to provide a continuous reference and daily record. Historically, Arrival Heights only had a wind recorder (since January 1984). A data logger was installed in January 1999 and measured air temperature, relative humidity and global solar radiation using a secondary network sensor, as well as wind speed and direction. A barometric pressure sensor was installed in 2001. A standard 10m mast was installed and all sensors were moved to the new Arrival Heights laboratory in 2007. 10-minute and hourly data are recorded. Data are retrieved and archived from both automatic stations daily, as well as manual observations from Scott Base and available on New Zealand's national climate database. From February 2019, mercury theremometers and barometers were removed from Scott Base and Arrival Heights. Where applicable, these were replaced with electronic instruments. A weighing precipitation gauge was also installed in February 2019 for the measurement of solid precipitation at Scott Base. GET DATA: https://cliflo.niwa.co.nz/

  • This metadata record represents meteorological data and in situ and isotopic measurements of the isotopic ratio of water vapor from the ablating ice from two lakes in the McMurdo Dry Valleys, Antarctica. Lake ice and water samples (from the surface water and at depth via SCUBA) were collected in vials. Ice samples at Lake Bonney were collected daily, and at Lake Fryxell samples were collected approximately twice per day. Lake ice samples were also collected at Lake Fryxell along three transects spaced approximately every 300 to 500 m (meters) across the lake surface. Water vapor isotope flux measurements were collected via air inlets which were installed at 0.5, 1.0, and 3.0 m on the tower using ¼″ OD Teflon tubes. The lines were insulated and continuously pumped at a flow rate of approximately 10 L min−1 using a secondary pump. Meteorological measurements with a Vaisala HMP100 probe for temperature and relative humidity readings and an RM Young wind vane (model 05108) for wind velocity measurements, at heights of 3.0 and 0.5 m. Air temperature, relative humidity, wind velocity, and lake surface temperature measurements were recorded every minute via a Campbell Scientific CR1000 data logger.

  • There are nine soil climate stations located in the McMurdo Sound region of Antarctica that were established starting in 1999 through 2011. Four of the stations are in the Dry Valleys and four are located along the coast. The ninth station is located on Mt. Fleming near the polar plateau. Each climate station measures atmospheric parameters (air temperature, relative humidity, wind speed and direction, and solar radiation) and soil parameters (soil moisture and temperature) that extend from the active layer (seasonally thawed layer) into the permafrost. Recorded measurements are made on an hourly basis. At each climate station the soils have been sampled and characterized at the Kellogg Soil Survey Laboratory. There are two borehole stations at Bull Pass and Marble Point which measure ground temperature and are used to study permafrost temperatures and active-layer thermal regimes to a depth of 30m. Further station and borehole details including the instruments' specification, maintenance, and measured variables are described in each site's data "_description" folder.
