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.
This work was funded by NERC standard grant NE/R000654/1 and NERC MOSAiC program NE/S002545/1.

- Statement
- 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).
