NOTE: This is a MONTHLY product.

10-09-2020: A minor version bump (+0.01) has been applied to all CALIPSO data products due to a required upgrade to the operating system on the CALIPSO production cluster. All algorithms were re-compiled to process in this new environment with no change to the underlying science algorithms or inputs.

The Blowing Snow monthly data product is a new technique for the detection of blowing snow events determined from CALIOP lidar atmospheric attenuated backscatter measurements to obtain the spatial and temporal frequency, layer height, and optical depth of blowing snow events over Antarctica for 2006 through the present.

The average monthly blowing snow frequency over Antarctica for the period of 2006-2017.
