Snow grain size is an essential property required for many applications: cold regions hydrology, polar and mountain climatology, optical and microwave remote sensing, snow chemistry, etc. However, field and laboratory measurements of snow grain size are notoriously difficult and impaired by the coexistence of inconsistent definitions. Several instruments and methods based on very different physical principles (optical, gas adsorption, tomography, stereology) have been developed in the last decade, with differences in terms of reproducibility, acquisition time and vertical and horizontal resolution in the field. In recent years, grain size measurements have been conducted by different groups in a wide variety of environments. However, little is known about the accuracy of these methods due to the lack of an approved reference method and the insufficient number of inter-comparison exercises. This workshop will address these challenges et propose future actions.
