This dataset contains major ion chemistry and stable nitrate isotopic composition for i) daily aerosol and skin layer snow samples collected during January 2017, and ii) two snow pits at Kohnen Station, Dronning Maud Land, Antarctica. Funding was provided by the NERC grant NE/N011813/1.

Biologically relevant radiation has been recorded since February 1997 using a Bentham spectroradiometer at Rothera. The Bentham spectroradiometer is sited on the roof of the Bonner Laboratory at Rothera. It measures spectral global irradiance between 280 and 600 nm (wavelengths from below UV-B to the middle of the visible range) with a step size of 0.5 nm and a resolution of 1 nm. Scans are recorded at various time intervals depending on the time of day and season peaking at every 30 minutes while the sun is above the horizon from the beginning of September until the end of April. These scans can be used to measure the amount of solar radiation reaching the earth''s surface at Rothera. It provides particularly useful background data for studies on the effects of increased UV-B, due to the ozone hole, on the plants and microbes in regions around Rothera.

Automatic data loggers are often used to monitor environmental variables such as temperature (of air and soil), humidity, wind speed and radiation in microclimates where experimental or ecological studies are being carried out. Some loggers are only in operation for a few weeks or months while others have been run for several years. Loggers have been sited in a wide variety of locations from the sub-Antarctic (South Georgia), South Orkney Islands (Signy) various Peninsula sites (as far south as Alexander Island - 70S), and some continental localities (e.g. Victoria Land). These form an important data resource to the climate conditions experienced by Antarctic terrestrial organisms. Various types of logger are used. Sensors tend to be deployed at or near ground level and in and around particular types of vegetation, or other experimental sites, such as cloches. Loggers used include Grant, Delta-T, Campbell and Squirrels. Victoria Land data for Kay Island and Edmonson Point in 1995 and 1996 was collected under the BIOTEX 1 experiment of the SCAR BIOTAS (Biological Investigations of Terrestrial Antarctic Systems) Programme.
