title: SID-3 Liquid and Ice Phase Particle Size Distributions measured during ACLOUD

description: This data set contains particle size distributions of spherical and aspherical cloud particles between 5 and 45 microns with a 10-second time resolution calculated from the Small Ice Detector Mark 3 (SID-3). The SID-3 detects individual cloud particles passing a 532 nm laser beam using two nested trigger detectors. The trigger signal is recorded as a histogram with a maximum rate of 11 kHz that can be used to derive particle size distributions by using the procedure described in Vochezer et al. (2016), doi:10.5194/amt-9-159-2016. For a sub-set of triggered particles a two-dimensional (2-D) scattering pattern is recorded that can be analysed for particle sphericity by a specifically developed image analysis software. Occasionally, coincidence sampling in the camera field of view causes optical distortions of the 2-D scattering patterns of liquid droplets and, consequently, a misclassification of such scattering patterns to be aspherical by the classification software. For the subsequent identification and re-classification of coincidence scattering patterns a machine learning (ML) algorithm was developed. From the numbers of observed spherical and aspherical 2-D scattering patterns the fractions of spherical and aspherical particles are derived. Multiplication of those number-based fractions with the total particle size distribution yields phase-specific particle size distribution. The uncertainty due to the fact that the imaged particles are a subset of all sampled particles can be estimated from the Clopper–Pearson confidence limits. The data was collected during the Arctic CLoud Observations Using airborne measurements during polar Day (ACLOUD) campaign, which was conducted northwest of Svalbard (Norway) between May 23 and June 6, 2017. The measurement area comprises an area north of Svalbard, approximately between 78 and 82°N. The SID-3 instrument was installed in the Polar-6 aircraft during the ACLOUD campaign. The data is in NetCDF format and contains the total number concentration, the total particle size distribution, the total number of aspherical particles, the aspherical particle size distribution, the total number of spherical particles, the spherical particle size distribution and the upper and lower limits for the total aspherical and spherical particles and aspherical and spherical particle size distributions calculated using Clopper–Pearson confidence limits.

title: Validation data of sea ice surface albedo derived from the ACLOUD and AFLUX campaign measurements

description: Data of the broadband albedo averaged at the MODIS pixel, which was derived from the measurements by either pyrometer (shortwave, in the range of 200-3600 nm) or albedometer (visible in 400-700nm, near infrared in 700-2100, and shortwave in 400-2100) during the ACLOUD and AFLUX campaigns. This data is intended to validate the RTM-SciML (short for radiative transfer model - scientific machine learning model) algorithm, which uses top-of-atmosphere radiance data from MODIS as input to perform albedo retrieval for sea-ice surface. In addition to the satellite and measured data, the pixel type and surface classification retrieved using scientific machine learning models (https://tc.copernicus.org/preprints/tc-2021-397/) are also included.

title: Properties of liquid-dominated clouds over the ice-free and sea-ice-covered Arctic Ocean during ACLOUD

description: This dataset contains retrieved microphysical properties of liquid-dominated clouds from the Arctic CLoud Observations Using airborne measurements during polar Day (ACLOUD, May/June 2017) airborne campaign. The retrieved parameters of the dataset are effective radius, optical thickness and effective liquid water path. ACLOUD took place in the vicinity of Svalbard over the ice-free and sea-ice-covered Arctic Ocean. A statistically analysis of this dataset and an explanation of the retrieval method is published in Klingebiel et al. (2023, https://doi.org/10.5194/acp-2022-848).

title: Snow covered digital elevation model and snow depth product (2019), Trail Valley Creek, NWT, Canada

description: This dataset contains one snow covered digital elevation model (DEM) and one snow depth product from April 10, 2019 over the Trail Valley Creek research watershed, Northwest Territories, Canada (68°44'25 N, 133°29'36 W). The products are derived from airborne laser scanner data that was collected with a Riegl VQ-580 on board the Alfred Wegener Institute's POLAR-6 science aircraft. The snow covered DEM contains the snow covered landscape elevations, i.e. the terrain and the snow. To obtain snow depth, a snow-free digital terrain model (DTM) needs to be subtracted from the snow covered DEM. We also provide a snow depth product, which we obtained by subtracting snow-free DTMs of Trail Valley Creek and the Inuvik to Tuktoyaktuk Highway (ITH) (both from August 2018) from the DEM including snow cover. Please note that the snow depth product covers only parts of the complete snow covered DEM. The data can be used for analysing spatial snow accumulation patterns.
