High-resolution floe size distribution of Arctic sea ice 2000-2014

This dataset contains the floe size distribution (FSD) data derived from high-resolution satellite imagery data acquired at two fixed locations in the Arctic Ocean. Satellite imagery data include MEDEA images and WorldView images. These satellite images have a spatial resolution of 1 m or higher, thus providing the FSD information, especially for small floes. The derived data contain floe size (calliper diameter), shape factor, minor/major axis, perimeter and area of the floes. This dataset has been used to evaluate the sea ice models with the FSD parameterisations. The retrieval of the FSD data was done by the University of Huddersfield team.

Statement

Methodology:

The FSD data were derived from high-resolution satellite imagery data (MEDEA and Worldview). For MEDEA images, the original images were cropped to remove the areas with clouds and missing data. The cropped images were then used to derive the FSD. For WorldView images, panchromatic images were used to derive the FSD. The floe size distribution was derived from those images using the algorithm described in Hwang et al. (2017).

Data collection:

Characteristics of satellite imagery data used to derive the data set are described below.





MEDEA: 1-m resolution visible (panchromatic) satellite imagery from the USGS Global Fiducials Library (GFL) ( https://glf.usgs.gov), declassified by the MEDEA group.





WorldView: A commercial satellite by Digital Globe ( https://www.digitalglobe.com). The FSD data was derived from panchromatic images of WorldView-1 (WV1) and WorldView-2 (WV2).

Data quality:

The data quality was checked by manual inspection for each imagery data. It should be noted that some of the small floes can be erroneous due to noises or internal variations within the images. However, no minimum threshold for the smallest detectable floes was set for this dataset (i.e., the smallest floe equals one image pixel). This is to provide flexibility for the users to determine the minimum threshold for the smallest detectable floes. For instance, in a model evaluation study, the minimum threshold was set to be 30 m (i.e., the floes small than 30 m in diameter were discarded from the analysis).
