Snow water equivalent at QAS_U
No full textThe SnowFox sensor observes snow-water equivalent (SWE) by the attenuation of cosmic-ray neutrons. The sensor is located close to a PROMICE automatic weather station to complement the snow depth measurements

Typical sampling is of three surfaces per site per year, i.e. dark, under the albedometer and representative.
cell counts and notes appear in the file named:
A report (in preparation) outlines notes, figures and an analyses of biological and abiotic impurities around a selected number of PROMICE and GC-Net weather stations on the Greenland ice sheet (GrIS) of samples collected during the summer of 2024. This is the second year in which samples are collected as part of a monitoring programme of glacier ice algae on the GrIS. In 2024, PROMBIO aimed to conduct a randomized and more detailed sampling of one of the PROMICE weather stations transect, the QAS transect, in order to characterize in depth one of the dark regions of the ice sheet. Furthermore, samples were also collected at TAS-A and KAN-L weather stations. Poor weather conditions during the summer of 2024 has limited work in the other PROMICE and GC-Net weather stations. In conjunction with data from 2023, this report provide a basis of ground-truth data for validation of remote satellite and future modelling work on estimation of biological and abiotic impurities on the GrIS.
At the QAS sites was a detailed (higher sample size) sampling. At TAS_A and KAN_L, the sampling is of three surfaces per site per year, i.e. dark, under the albedometer and representative.

QAS winter balance survey 2025-04-23
No full textAs part of a PROMICE mission, Jason Box and Rasmus Bahbah (Nielsen) made a snow water equivalent (SWE), a.k.a. winter balance survey at seven southern Greenland ice sheet locations spanning 241 m to 950 m above sea level.
The survey date is essentially at the end of the 2024/2025 accumulation season, i.e. prior to the start of the 2025 ablation season. The seven sites are host to other measurements, e.g.: SWE is being measured sub-daily by SnowFox at QAS_L, ice ablation is measured sub-daily at AWS sites (QAS_L, QAS_M, QAS_U) and annually (summer balance) at stake sites, e.g. Q2,Q3,Q4,Q5.
A 9 cm Kovacs coring device was used and a snow metrics balance and a plastic bag to contain core samples. one to five coring runs were made and from the individual runs it is possible to get more vertical resolution on the snow density
A .xlsx file contains a data summary from which a .csv file was also exported. see the .pdf for scans of the field notes/raw data
The zip archive includes: 2025 04 23 QAS SWE survey - stakes - 7 pages.pdf, snow-profiles-QAS-2025.csv, Figures, snow-profiles-QAS-2025.xlsx, plot_snow-profiles-QAS-2025.py
the work is related to Herman et al (2018), JGR, cited below and in 2018 there was another SWE survey available already in the SumUp dataset
Wind speed and direction at the summit of A. P. Olsen Ice Cap
No full textWind speed and direction has been measured at the summit of A. P. Olsen Ice Cap since 2009 - with a major datagap from 2019 to 2024 - at the climate station: ZAC_A.
Wind direction has here been corrected for climate mast rotation so that wind direction is given as degrees from geographical north

Detailed information on the map units is available in the GEUS Greenland Intrusive and Stratigraphic Database using the GU-codes shown in brackets in the legend (https://doi.org/10.22008/FK2/F9MBNJ). Information on mineral occurrences is available in the Greenland Mineral Resources Portal (https://www.greenmin.gl).
Topographic base: Geodetic Institute maps at 1:200 000 from 1954 with major revision of the ice margin and glaciers based on 1:150 000 aerial photographs from 1985–1987 and Sentinel 2 satellite scenes from 2019. All heights are in metres. Additional lake heights are from the Danish Agency for Data Supply and Infrastructure (now the Danish Agency for Climate Data): Højdemodel Grønland (https://dataforsyningen.dk/data/4780, accessed September 2023). Ground exposed by ice retreat since initial compilation in 1988–1989 is identified in the legend. 1949 ice margins are from Geodetic Institute maps. Ice margins recorded during expeditions by Robert E. Peary in 1892 and Lauge Koch in 1922 are approximate. Ice altimetry and thickness are based on data from Morlighem et al. (2017), bathymetry is from Morlighem et al. (2022). Landslides are modified from GEUS internal data, for methodology see Svennevig (2019). Authorised place names are from Oqaasileriffik (The Language Secretariat of Greenland), with supplementary names from Laursen (1972).
