AntAir ICE is an air temperature dataset for terrestrial Antarctica, the ice shelves, and the seasonal sea ice around Antarctica in a 1km2 spatial grid resolution and a daily temporal resolution available from 2003-2021. AntAir ICE was produced by modelling air temperature from MODIS ice surface temperature and land surface temperature using linear models. In-situ measurements of air temperature from 117 Automatic Weather Stations were used as the response variable. Each day has a bricked spatial raster with two layers, saved as a GeoTIFF format and in the Antarctic Polar Stereographic projection (EPSG 3031). The first layer is the predicted near surface air temperature for that day in degree Celsius * 10 and the second layer is the number of available MODIS scenes for that day ranging from 0 to 4. Areas with cloud contamination or without sea ice are marked with no data. Files for each year (2003-2021) are compressed with a ZIP files for each quarter. Python 3.8 was used for conversion of the MODIS products from HDF files to raster and all data handling and processing was thereafter done in R version 4.0.0. All data processing and modelling procedures are available as R scripts on a public Github repository: https://github.com/evabendix/AntAir-ICE. Using this code it is possible to download new available MODIS LST and IST scenes and apply the model to continue the near-surface air temperature dataset.

An automated weather station operates at Cape Adare (-71.30492, 170.23256). The station was established in 2014 and continues to transmit live data. Data are logged every 30 minutes. Parameters: - Air Temperature (C) - Relative Humidity (%) - Solar Radiation (W/m2) - PAR (uE) - Wind Speed (m/s) - Wind Gust (m/s) - Wind Direction (true bearing degrees) GET DATA: adminteam@antarcticanz.govt.nz

Automated weather stations were installed to measure local scale weather conditions at Miers Valley, Miers Ridge, Commonwealth Glacier, Cape Christie, and Haystack Mountain. Miers Valley, Miers Ridge and Haystack Mountain stations have been operating since early 2021, Haystack, Commonwealth Glacier and Cape Christie were installed in December 2021, 2022, and 2023, respectively. Data are available on request in NetCDF. Parameters: - average air temperature (C) - average relative humidity (%) - average short wave in (W/m2) - average pressure (hPa) - wind speed (ms-1) - wind direction (true bearing degrees) - wind standard deviation Coordinates: - Miers Valley (-78.09805, 163.794283) - Miers Ridge (-78.123205, 163.863319) - Commonwealth Glacier (-77.563987, 163.281064) - Cape Christie (-72.29722222, 169.9847222) - Haystack Mountain (-77.05, 162.585) GET DATA: marwan.katurji@canterbury.ac.nz

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/

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.
