A global compilation of in situ data is vital to evaluate the quality of ocean-colour satellite data records. Here, we describe data compiled for the validation of ocean-colour products from the ESA Ocean Colour Climate Change Initiative (OC-CCI). The data were acquired...

This data set unites the individual data of the Airborne measurements of radiative and turbulent FLUXes of energy and momentum in the Arctic boundary layer (AFLUX) campaign, carried out in spring northwest of Svalbard (Norway). The objective of AFLUX was to study turbul...

Since December 2012 AWIPEV operates a commercial Wind Lidar (WindCube 200, Leosphere) on the roof of the AWIPEV observatory in Ny-Ålesund, which runs unattended and continuously. It uses the Doppler effect of an eye safe laser at 1.5 μm wavelength to measure the 3-dimen...

Aerosol optical depth (AOD) is measured by a sun photometer, type SP1a by Dr. Schulz & Partner GmbH in 17 wavelengths between λ = 369nm to 1023nm with a field of view of 1° × 1° and a time resolution of 1 minute. In winter 2012/13 a new sun photometer was installed and ...

This data set unites the individual data of the MOSAiC Airborne observations in the Central Arctic (MOSAiC-ACA) campaign, carried out in late summer 2020 northwest of Svalbard (Norway). The objective of MOSAiC-ACA was to study turbulent fluxes of energy and momentum in ...

The heat waves and droughts of 2018 / 2019 and in 2020 have had a devastating impact on the functioning of ecosystems and have led to an increasing vulnerability beyond the duration of heat waves (e.g. degradation and increased erosion, reduced carbon uptake by vegetati...

We provide continuous bihourly temperature and humidity data (November 2019 to March 2021) of four caves and three blowholes from arid and one of the largest contiguous karst areas in the world, the Nullarbor Plain in south Australia. The data were recorded with ten TGP...

Resilience to drought of relict Mediterranean Quercus pyrenaica populations in the southern Iberian Peninsula was analyzed in relation to historical records of land-use, combining dendroecological growth of adult trees and greenness (EVI) as proxies for secondary and pr...

The year 2020 marks the 200th anniversary of European settlers first encountering the 'noble expanse of water' of Lake George in New South Wales. Since 1820, unofficial observations and official measurements of the lake's water level have been recorded almost continuous...

The hemispherical-directional reflectance factor (HDRF) of snow surfaces was measured in Antarctica during austral summer in 2013/14. The HDRF was retrieved from airborne measurements using a digital 180° fish-eye camera onboard the research aircraft Polar 6 operated by...
