Snow and ice surface photogrammetry images collected during RV POLARSTERN cruise PS144

DOI

During the Polarstern cruise PS144 from August 2024 to October 2024 in the central Arctic Ocean a standard digital camera (Olympus E-M5) and a set of reference targets were used to take sets of images on 10 ice stations.From this, the surface topography and roughness at the centimeter scale can be retrieved (multi-image photogrammetry/ structure from motion), which is an important parameter for the microwave emission and scattering. The reference targets were distributed around a small ( ~ 0.35 m x 0.7m) area, and pictures were taken from different angles. Pictures were always taken with fixed focus length. All measurements were done within the vicinity of the footprint of the onboard microwave radiometers installed for the VAMPIRE project (that is, in about 25 m distance to the port bow of Polarstern mostly measured along T-shaped transects with side lengths of 5 to 7 meters). Up to three different sites were photographed (site numbering and locations are described in the data paper corresponding to https://doi.org/10.1594/PANGAEA.990496). The datasets consists of the raw measurements (the photos as .raw files). For more information about these measurements the user is referred to Chapter 6.4 of the cruise report.
