title: Harmonised LUCAS database classified by crop sequence type

description: Assessing the benefits of crop diversification – a pillar of the agroecological transition – on a large scale requires a description of current crop sequences as a baseline, which is lacking at the scale of the European Union (EU). This work is based on the Harmonised LUCAS in-situ land cover and use database for field surveys from 2006 to 2018 in the European Union (doi: 10.2905/f85907ae-d123-471f-a44a-8cca993485a2) to fill this gap, We completed this dataset with a crop sequence type information for each point under non-perennial agricultural land cover in 2012, 2015 and 2018. The dataset lucas_classified.csv includes 31 159 points. Variables "point_id", "nuts0", "nuts2", "th_lat", "th_long", "LC1_2012", "LC1_2015", "LC1_2018" are inherited from the Harmonised LUCAS databse. Variables "cereals", "corn", "rapeseed", "sunflower", "pulses", "rootCrops", "forageLeg", "grassland" correspond to the temporal frequencies of respectively cereals, corn, rapeseed, sunflower, pulses, root crops, forage legumes and grassland within the 2012, 2015 and 2018 crop sequence for each point. Variable "crop_sequence_type" is the crop sequence type assigned to each point, among eight options: cereals, corn and cereals, forage legumes and cereals, pulses and cereals, rapeseed and cereals, root crops and cereals, sunflower and cereals, temporary grasslands. This dataset could be used to map current dominant crop sequences in the European Union, as illustrated in the map attached, and to assess the benefits of future crop diversification.

title: Ground-penetrating radar surveys at three nunataks in the Hudson Mountains in the Amundsen Sea sector of West Antarctica, December 2019

description: This dataset contains data from three ground-penetrating radar surveys undertaken to image ice thickness and englacial stratigraphy during the 2019-20 Antarctic field season, as part of the International Thwaites Glacier Collaboration (funded by NERC and NSF). The ground-penetrating radar data are presented as SEG-Y, along with the GPS tracks of the surveys, presented as GPS Exchange Format (GPX). The subglacial extensions of ridges of three nunataks close to Pine Island and Larter Glaciers in the Hudson Mountains region were surveyed, with the aim of determining their suitability as subglacial bedrock drill sites. Those nunataks are Winkie Nunatak (74 degrees 51' 41.0" S/99 degrees 46' 49.4" W), Evans Knoll (74 degrees 51' 00.0" S/100 degrees 25' 00.0" W), and Webber Nunatak (74 degrees 47' 00.0" S/99 degrees 50' 00.0" W).

This work was funded by NERC grants NE/S00663X/1 and NE/S006710/1.
description: A snowmobile was used to tow a PulseEKKO 1000 ice penetrating radar (GPR) system with 200 MHz antennae mounted on a wooden Nansen sledge. The snowmobile was travelling at speeds of 3-7km/hr with the system set to continuous collection mode with an in-field stack of 4. A hand-held Garmin GPS was used to locate the position of radar survey lines. All radar data are presented in their raw, unprocessed form. 

At Winkie Nunatak, a broad grid consisting of seven 400 m-long cross profiles was collected perpendicular to the ridge line. These profiles were spaced at 100 m intervals away from the visible ridge line. A detailed grid of five 300 m-long lines was then collected at 25 m intervals. At Evans Knoll six radar lines were collected perpendicular to the ridge at 7-15 m line spacing, and one line was run parallel to the ridge crest through the centre of the grid. At Webber Nunatak, eight radar lines were collected perpendicular to the ridge expression at 50 m spacing, and one line was run away from the ridge tip through the centre of the grid. The lines increased in length from 150 m to 500 m with increasing distance from bedrock, due to the orientation of the steep ice slope running northwest.

title: CM SAF ClOud Fractional Cover dataset from METeosat First and Second Generation - Edition 1 (COMET Ed. 1)

description: This Thematic Climate Data Record (TCDR) provides cloud fractional cover (CFC) derived from the Meteosat Visible and InfraRed Imager (MVIRI) on board the Meteosat First Generation (MFG) and the Spinning Enhanced Visible and InfraRed Imager (SEVIRI)  onboard the Meteosat Second Generation (MSG) satellites. The covered time period ranges from January 1991 to December 2015, thus includes MFG 4 to 7 and MSG 1 to 3. Original thermal radiances were inter-calibrated by the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT) using the High Resolution Infrared Radiation Sounder (HIRS)  as a reference. 
The Meteosat CFC is presented as hourly, daily and monthly composites on a 0.05°x0.05° grid covering the entire Meteosat disk (Africa and Europe). The CFC data is derived from two Meteosat heritage channels by use of an advanced Bayesian retrieval algorithm. It employs continuous cloud scores, which are built on a contemporaneous clear sky background inversion. The Meteosat CFC is characterized by comparability to the SYNOP-based long-term CFC observations carried out at WMO ground stations. The Meteosat CFC is therefore useful to supplement the ground-based CFC estimates in areas with low station density or high spatio-temporal CFC variability. Along with the data, a comprehensive documentation including user guide, algorithm descriptions and extensive validation studies, is given.

title: Fluxes of Carbonyl Sulfide at Harvard Forest EMS Tower since 2010

description: Carbonyl sulfide (OCS), the most abundant sulfur compound in the atmosphere, controls the
 sulfur budget and aerosol loading of the stratosphere in times of low volcanic activity. OCS is
 also closely tied to the vegetative carbon cycle and may provide an independent measure of the
 photosynthetic uptake of carbon. However, the detailed nature of the biogeochemical cycling of
 OCS throughout the seasons in terrestrial ecosystems has not been thoroughly explored. We
 measured the seasonal response of the ecosystem flux of OCS above a deciduous temperate forest
 using an infrared laser absorption spectrometer at Harvard Forest (MA, USA) in 2011. Fluxes
 were calculated using two complementary approaches: gradient – flux (also known as flux –
 gradient; January – July, 2011) and eddy covariance flux (August – December, 2011), which
 agreed within the combined error for a period with both measurements. Strong uptake of OCS by
 the forest was observed during most of the growing season, but significant uptake also occurred
 when the deciduous leaves were not present. A strong diel cycle of mid-day OCS uptake was
 observed in May/June and August/September, consistent with OCS uptake by processes parallel to
 CO2 photosynthetic uptake, at the ecosystem scale, for these months. The results show that
 while overall OCS and CO2 both show evidence of vegetative uptake, the OCS flux cannot be
 explained by this process alone and the relationship between OCS and CO2 changes throughout the
 year above this mixed deciduous forest. The data imply that terrestrial uptake of OCS, and
 hence the stratospheric sulfur cycle, are potentially quite sensitive to extremes in
 temperature and soil moisture.

title: Snow and ice thickness from airborne electromagnetic (EM) induction sounding over polynya event and surrounding multi-year ice off the North Coast of Greenland in March 2018, 2018-03-30

description: Results of airborne-borne electromagnetic (AEM) measurements of total (ice + snow) sea-ice thickness performed in March 2018 in the Wandel Sea and adjacent Arctic Ocean up to 84.5 °N are presented. The data set was acquired from fixed-wing aircraft POLAR 5 surveys from the port of station Nord (Greenland) as part of the IceBird spring campaign 2018. The surveys were conducted on March 30 and 31 over newly formed ice of a closing polynya and the surrounding multi-year ice (MYI). Total thickness was recorded with a point spacing of approximately 6m. In addition, the surrounding MYI between 82.4°N and 84.5 °N and 14.2 °W and 8.9 °E was surveyed. The AEM survey showed mean and modal thicknesses of the newly formed ice of 1.96 +-1.5 and 0.95 m, respectively. The MYI surrounding the polynya had a mean and modal total thickness (snow + ice) of 2.1 +- 1.4 m and 2.0 m, respectively. Version 1.0, for details of processing see: Hendricks, S. and Rohde, J.

title: CLARA-A2.1: CM SAF cLoud, Albedo and surface RAdiation dataset from AVHRR data - Edition 2.1

description: The CLARA-A2.1 record provides cloud properties, surface albedo and surface radiation parameters derived from the AVHRR sensor onboard polar orbiting NOAA and METOP satellites. It includes and temporally extends the second version of the record (Karlsson et al., 2016; CLARA-A2 DOI:10.5676/EUM_SAF_CM/CLARA_AVHRR/V002) now providing data from 1982/01 to 2019/06, i.e., for 37.5 years. Original visible radiances were inter-calibrated and homogenised, using MODIS data as a reference, before applying the various parameter retrievals. The inter-calibration was based on an original method introduced by Heidinger et al. (2010) which was updated (MODIS Collection 6) and extended. CLARA-A2.1 features a range of cloud products: cloud mask, cloud top temperature/pressure/height, cloud thermodynamic phase, and (for liquid and ice clouds separately) cloud optical thickness, particle effective radius and cloud water path. Cloud products are available as monthly and daily averages and also as daily resampled global products (Level 2b) for individual satellites. Cloud parameter results are also presented as multi-parameter distributions (i.e., joint frequency histograms of cloud optical thickness, cloud top pressure and cloud phase) for daytime conditions. Surface albedo is presented as monthly and pentad (5 day) averages of the broadband black-sky albedo and is derived using all available data during the studied period. Surface radiation products are provided as monthly averages for the downwelling shortwave (including also daily averages) and the down- and upwelling longwave components. The monthly and daily averages are available on a 0.25°x0.25° global grid. Surface albedo and cloud products are also provided in two equal area grids with a resolution of 25 km x 25 km covering the polar regions. Daily resampled cloud products (level 2b) are provided in a global grid with a resolution of 0.05°x0.05°. For the latter, also a probabilistic cloud mask is added as an experimental product. A summary of the CLARA-A2.1 characteristics and a comprehensive evaluation of the data are available through a comprehensive set of documentations documents including user guides and, algorithm descriptions.

title: Analog laboratory experiments of gravity gliding in salt-bearing rift basins

description: Salt tectonic processes in rift basin are mainly driven by sub- and supra-salt faulting and sedimentary loading. However, since the formation of a rift basin is often accompanied and followed by thermal subsidence, flanks of the rift basin are tilted, which induces an additional basinward directed driver for salt tectonics. We designed a new experimental analog apparatus integrating the processes of sub-salt graben extension and tilting of the flanks so that their overlapping effects on the deformation of a viscous substratum and the brittle overburden can be simulated. In total, seven experiments were performed in the analog laboratory of the Institute of Geophysics of the Czech Academy of Science (Prague, Czech Republic) and presented in the paper related to this data publication. The experimental surface was recorded by stereoscopic cameras. Images were acquired and processed by the StrainMaster© (LaVision GmbH) 3D digital image correlation (DIC; Davis 10.2) software. The data set presented here includes(1) data of the DIC:- Displacement and strain maps showing final displacement (total displacement, x-displacement, z-displacement) and strain (normal strain in x-direction) observed at the experimental surface as well as averaged values of these parameters related to experimental time(2) data related to the scaling procedure:- Data of the dimensionless Argand number and Brittle-ductile-coupling- Data of the density of natural sediments and of analog materialsDetailed descriptions of the experiments, method and results can be found in Warsitzka, et al. (2021) to which this data set is supplement. The subfolders in the data are named according to the experiments in the related paper.

description: We conducted our study in a cushion bog dominated by Astelia pumila on Tierra del Fuego, Argentina (54.972°S, 66.734°W). We experimentally investigated how a cushion bog plant community responded to elevated surface temperature conditions. We installed a year-round passive warming experiment using semicircular plastic walls that raised average near-surface air temperatures between 0.4°C and 0.7°C (at the three of ten treatment plots which were equipped with temperature sensors). We conducted chamber gas flux measurements to characterize differences in carbon dioxide exchange dynamics between the treatment and control plots.
