Water table depth for Danish lowland soils
No full textThe map depicts a long-term average water table depth in Danish lowland soils at 10 m spatial resolution. The long-term average represents summer conditions for a time period from 2000 to 2020. The map has been generated using a gradient boosting with decision tree algorithm, similar to the method presented in https://doi.org/10.3389/frwa.2021.701726. The unit of the map is cm below ground

DK-model2019 - modelsetup (area: DK1, DK2)
No full textThis .zip file contains DK-model2019, area DK1 and DK2 (Sjælland og Øerne), as a coupled MIKE SHE/MIKE HYDRO River model setup.
The National Hydrological Model (DK-Model) is set up in the MIKE SHE/MIKE HYDRO River model system, which constitutes a deterministic fully distributed and physically based model complex for simulating the freshwater cycle. The model includes a description of the surface runoff (OL), the unsaturated zone (UZ), the saturated groundwater zone (SZ), including drainage runoff, as well as water flow in the streams (MIKE HYDRO River). The numerical hydrological model is set up in a discretization of 500 x 500m grid for the whole country, except for Bornholm, which is set up with a discretization of 250x 250m

Supplementary files for: A new Middle Pleistocene interglacial occurrence from Ejby, Sjælland, Denmark
No full textDespite more than a century of investigations, parts of the Quaternary stratigraphy of Denmark with their fragmented record of deposits remain ambiguous. Here we describe a newly found interglacial clay deposit from Ejby on Sjælland, Denmark from a borehole at 55.695°N, 11.839°E (terrain elevation 5.7 m above sea level). We place the new occurrence on record and provide details of the macrofossil analysis of the sample. The clay contains remains of the present-day temperate bivalve Corbicula fluminalis and the caddis fly Hydropshyche contubernalis – both inhabiting rivers. The presence of C. fluminalis indicates that the deposit most probably is of Middle Pleistocene age, older than the last interglacial, the Eemian
SICEv2.3.2 Iceland snow and ice broadband albedo and surface optical properties from Sentinel-3’s OLCI at 1000 m resolution, 2017-2023

Description
For multiple Arctic glaciated regions (Table 1), 1km daily data (Table 2) from the SICE v1.6 algorithm, see Wehrlé et al (2021) and Kokhanovsky et al (2019) for details. Broadband albedo "albedo_bb_planar_sw" is after Kokhanovsky et al (2019). "BBA_combination" is albedo_bb_planar_sw for albedo_bb_planar_sw values above 0.565 and is combined with an ampirical albedo for albedo_bb_planar_sw below or equal to 0.565, see Wehrlé et al (2021). Data format is GeoTiff in the EPSG:3413 - WGS 84 / NSIDC Sea Ice Polar Stereographic North. We suggest using rasterio to read the data files. The data are also available from https://thredds.geus.dk/

Vertical ice-sheet temperature profiles at three sites in Northwest Greenland
No full textThis folder contains the source code for solving 1-D vertical ice-sheet temperature profiles at three sites in Northwest Greenland (Camp Century, NEEM and Site II). Our numerical model solves the vertical ice temperature profile based on vertical heat diffusion, vertical heat advection, and heat production associated with internal deformation. For each of the three sites, we provide three files: (1) numerical code, (2) observed ice temperature data, and (3) graphic summary of model output. The code is provided as an annotated .m file, which can be run in either MATLAB (close source) or Octave (open source) software
