title: GeoBasis Zackenberg - Snow properties - Snow cover (Aucella south lower slope)

description: The snow cover is computed for the region covering the lower slope of Aucella, towards the South and Young Sound. The region corresponds to the area named 10 in the map in: GeoBasis_Zack_Snow_properties_Aucella_S_low_Snow_cover.pdf.
Snow cover is computed from orthorectified digital photos taken from the slope of Zackenberg, ca. 480 meters above sea level. The cameras used to capture the digital photos were: 1998 - 2005-06-30: Kodak DC50, 2005-06-30 - 2008-05-03: Kodak CX 6200 RDC 365, 2008-05-03 - now: HP Photosmart E427. The images are captured every day at 13:20, which is solar noon in the Zackenberg valley. Snow cover data from 2003-2005 is missing.

title: GeoBasis Zackenberg - Snow properties - Snow density (bulk density)

description: Snow bulk density is measured manually in various places in the Zackenberg valley, during snow covered periods. In this dataset every position is given with its UTM coordinates (WGS 84, UTM Zone 27N) and with the name of the location, where measurements are conducted in the vicinity of existing plots. The densities are never sampled within the existing plots (unless otherwise stated), but in a radius of at least 10 meters from the plot, in an area in which the conditions and characteristics of the snowpack are similar to the given plot. The positions of all the locations are given here in UTM coordiantes (WGS 84, UTM Zone 27N). In cases where total snow depth is missing, snow depth was larger than the measuring equipment, see remarks.

title: GeoBasis Zackenberg - Snow properties - Snow depth (manual probing)

description: Snow depth is measured manually in various places in the Zackenberg valley, during snow covered periods. In this dataset the position of every snow depth measurement is given in either longitude/latitude or in UTM coordinates (WGS 84, UTM Zone 27 N). Several measurements are from locations scattered in the Zackenberg valley, but measurements are also performed in two transects. One (called SNZ) from the coastline towards the top of Aucella and another (SNM), which is a transect of the central part of the Zackenberg valley (see map in: GeoBasis_Zackenberg_Snow_properties_Zackenberg_valley_Snow_depth.pdf). Furthermore systematic snow depth measurements are performed in transects near the ZEROCALM plots (ZC-1: UTM: NW-corner: 8264856 mN, 513363 mE
 NE-corner: 8264847 mN, 513461 mE

444 measurements were recorded as -1 (and a few as -2), these have been set equal to 0/no snow.

title: GeoBasis Zackenberg - Snow properties - Snow Pack Analyzer

description: The snow pack analyzer is situated on a well-drained cassiope heath in the heart of the main research area in the Zackenberg valley. The snow pack analyzer was installed in August 2013. The station measures the water content, the ice content and the density of the snow in 10, 30 and 50 cm above the ground, when snow is present, using 60 mm wide capacitance ribbons. 
Unfortunately, due to technical problems, the snow depth didn't work properly for the first years, therefore snow depth measurements from the Climate station (situated approximately 200 meters south of the SPA), has been included in the file, see remarks. For periods where snow depth measurements exists from both stations they correspond very well. Data from the three capacitance ribbons is only published for periods where the individual ribbon was snow covered.
Adjacent to the capacitance ribbons a SSG-Snow scale, covering an area of 6.72 m2, has been installed. The scale measures the snow water equivalent over this area. Negative measures from the scale have been set to zero. Missing data is due to various technical problems.
From 2013-2017 ice content, water content and density measurements from the different horizontal bands have been post corrected with 60 %, as the originally supplied bands were too thin, resulting in erroneous measurements.

title: GeoBasis Zackenberg - Snow properties - SNZ GeoRadar snow depth

description: Snow depth is measured using GeoRadar along the SNZ transect running from the coastline towards the top of Aucella (ending in about 400 meters above sea level). Measurements are primarily conducted by end of winter, before snow melt is initiated. Positions are given in UTM coordinates (WGS 84, UTM Zone 27 N). Systematic measurements with GeoRadar were implemented in the GeoBasis snow monitoring in 2016. The measured two-way travel time is used to estimate the snow depth by relating this to manual measurements of the snow depth performed along the transect. From linear relationships between the manually measured depths and the travel time, an approximated velocity is found and the snow depth estimated from depth = velocity * one way travel time. For all transects the two way travel time, manual measurements, the approximated velocity and estimated snow depth is recorded alongside the coordinates and information regarding the frequency of the antenna used.
