title: A spatially-explicit database of wind disturbances in European forests over the period 2000-2018

description: We present a database of wind disturbances in European forests (FORWIND). The data set corresponds the data presented in the paper “A spatially-explicit database of wind disturbances in European forests over the period 2000-2018” which has been submitted to Earth System Science Data (https://www.earth-system-science-data.net/).FORWIND comprises more than 80,000 spatially delineated areas in Europe that were disturbed by wind in the period 2000-2018, and describes them in a harmonized and consistent geographical vector format. The FORWIND dataset contains records as polygon features in shapefile format (.shp). The geometry of a feature is stored as a shape comprising a set of vector coordinates corresponding to the boundaries of the area of a given wind disturbance. Records are georeferenced in geographical coordinates, i.e. latitude and longitude, following the WGS84 standard (EPSG:4326). Basic attributes of each disturbance are provided in an associated table, stored in a .dbf file and include: * identifier code (Id_poly)* date of event (EventDate) * storm name (StormName)* type of event (EventType) * country (Country)* area affected [in hectares] (Area)* perimeter [in meters] (Perimeter) * damage degree [in %] (Damage_deg)* acquisition method (Methods)* data provider (Dataprovid)* source (Source) Missing data are reported as -999.<br> Correspondence to: Giovanni Forzieri (giovanni.forzieri@ec.europa.eu)<br>

title: SPICEcore Advection

description: The South Pole Ice Core (SPICEcore), which spans the past 54,300 years, was drilled far from an ice divide such that ice recovered at depth originated upstream of the core site. If the climate is different upstream, the climate history recovered from the core will be a combination of the upstream conditions advected to the core site and temporal changes. Here, we evaluate the impact of ice advection on two fundamental records from SPICEcore: accumulation rate and water isotopes. We determined past locations of ice deposition based on GPS measurements of the modern velocity field spanning 100 km upstream, where ice of ~20 ka age would likely have originated. Beyond 100 km, there are no velocity measurements, but ice likely originates from Titan Dome, an additional 90 km distant. Shallow radar measurements extending 100 km upstream from the core site reveal large (~20%) variations in accumulation but no significant trend. Water isotope ratios, measured at 12.5 km intervals for the first 100 km of the flowline, show a decrease with elevation of -0.008‰ m-1 for δ18O. Advection adds approximately 1‰ for δ18O to the LGM-to-modern change. We also use an existing ensemble of continental ice-sheet model runs to assess the ice sheet elevation change through time. The magnitude of elevation change is likely small and the sign uncertain. Assuming a lapse rate of 10°C per km of elevation, the inference of LGM-to-modern temperature change is ~1.4°C smaller than if the flow from upstream is not considered.

title: Sea surface temperatures, alkenones and sedimentation rate from ODP Hole 161-977A

description: A continuous high-resolution Western Mediterranean sea surface temperature (SST) alkenone record spanning the past 250,000 years shows that abrupt changes were more common at warming than at cooling. During marine isotope stage (MIS) 6, SST oscillated following a stadial-interstadial pattern but at lower intensities and rates of change than in the Dansgaard/Oeschger events of MIS 3. Some of the most prominent events occurred over MISs 5 and 7, after prolonged warm periods of high stability. Climate during the whole period was predominantly maintained in interglacial-interstadial conditions, whereas the duration of stadials was much shorter.

title: Pollen data of the last 500 ka BP at Lake Ohrid (south-eastern Europe)

description: Here we present the pollen data obtained for the DEEP core of Lake Ohrid located at the border between Albania and F.Y.R. of Macedonia. The very long sequence covers the last 500 ka BP in ca. 200 m. The study has been carried out by several European palynological laboratories. The age model of this part of the core is based on 10 tephra layers and on tuning of biogeochemical proxy data to orbital parameters. The original paper, published by Sadori et al. 2016 (https://doi.org/10.5194/bg-13-1423-2016), has been followed by a corrigendum due to chemical procedure problems that affected 104 samples. The record shows a progressive change from cooler and wetter to slightly warmer and drier interglacial conditions. This shift in temperature and moisture availability is visible also in vegetation during glacial periods. Pollen results support the notion that Lake Ohrid has been a refugium area for both temperate and montane trees during glacials.

title: Surface Carbonate Chemistry of the Red Sea (offshore and coastal)

description: The Tara Oceans Expedition (2009-2013) was a global survey of ocean ecosystems aboard the Sailing Vessel Tara. It carried out extensive measurements of evironmental conditions and collected plankton (viruses, bacteria, protists and metazoans) for later analysis using modern sequencing and state-of-the-art imaging technologies. Tara Oceans Data are particularly suited to study the genetic, morphological and functional diversity of plankton. The present data set includes properties of seawater, particulate matter and dissolved matter that were measured from discrete water samples collected with Niskin bottles during the 2009-2013 Tara Oceans expedition. Properties include pigment concentrations from HPLC analysis (10 depths per vertical profile, 25 pigments per depth), the carbonate system (Surface and 400m; pH (total scale), CO2, pCO2, fCO2, HCO3, CO3, Total alkalinity, Total carbon, OmegaAragonite, OmegaCalcite, and dosage Flags), nutrients (10 depths per vertical profile; NO2, PO4, N02/NO3, SI, quality Flags), DOC, CDOM, and dissolved oxygen isotopes. The Service National d'Analyse des Paramètres Océaniques du CO2, at the Université Pierre et Marie Curie, determined CT and AT potentiometrically. More than 200 vertical profiles of these properties were made across the world ocean. DOC, CDOM and dissolved oxygen isotopes are available only for the Arctic Ocean and Arctic Seas (2013).

title: Virtual catchment simulation based on the Neckar region

description: Project: Data Assimilation for Improved Characterization of Fluxes across Compartmental Interfaces - Model simulations of water and energy fluxes in the subsurface-landsurface-atmosphere system (SLAS) are important ingredients to climate and weather prediction, flood forecasting, water resources management, agriculture, and water quality control. Due to the immense scale complexity of terrestrial systems already the estimation of its state - which is a prerequisite of any prediction - is often insufficient despite the wealth of observations available nowadays from in-situ and remote sensing. Data assimilation optimally exploits observations for the estimation of system state evolution, but different philosophies and methods exist in the geoscientific disciplines of meteorology, surface, vadose-zone and groundwater hydrology concerning the structure of SLAS models and its use in data assimilation. In order to improve predictions for terrestrial systems we believe that a unified data assimilation framework is essential including simulation platforms that treat the SLAS in an integrated fashion and avoid compartmentalization of the terrestrial system. The development of such a data assimilation framework is the prime objective of the Research Unit. Homepage of project see: http://for2131.de/ All simulations were conducted on the JUQUEEN and JUWELS supercomputers at Jülich Supercomputing Centre (JSC) at Forschungszentrum Jülich. Compute time was granted by the Gauss Centre for Supercomputing (GCS) and the John von Neumann Institute for Computing (NIC). This project is funded by DFG (Deutsche Forschungsgemeinschaft, https://www.dfg.de/en/index.jsp). Summary: This version of the fully coupled catchment simulation features the atmospheric model COSMO run at 1.1km (0.01°rotlat/lon grid), the land surface model CLM and the groundwater model Parflow, both run at 400m (regular lat/lon grid). Coupled with OASIS3-MCT.

title: Physical and chemical data for dust deposited on Colorado Rocky Mountain snow cover during water year 2013 through water year 2016.

description: Atmospheric particulate matter deposited to snow cover diminishes snow-surface albedo and results in early onset and rapid snow melting, challenging management of downstream water resources. We present here physical and chemical data from snow samples from 14 sites during the melt seasons of water years 2013-16 across 60,000 km2 of the central Rocky Mountains within the Upper Colorado River basin. The samples represented the last remaining particulate-laden surfaces after individual dust layers and particles from background fallout had merged. The samples were examined for relations among properties of spectral reflectance, types and amounts of light absorbing particles (LAPs), chemical composition, and particle sizes.
