Abstract:
The dataset contains subset of doi:10.1594/PANGAEA.990221 restricted to only migrating barchans, contains in addition the characteristic time of reorientation of snow barchans in minutes (time_inte), which corresponds to the duration required for the integrated flux direction (available in the dataset doi:10.1594/PANGAEA.990228) to align with the barchan orientation.

Comment:
This dataset has been carefully reviewed and curated in accordance with PANGAEA's exceptionally high quality standards. However, due to discontinued communication from the authors' side, it did not receive the usual formal approval by the authors and therefore lacks final scientific validation.
