Snow on Arctic sea ice

Below you can find the reconstruction of snow depth on Arctic sea ice published in our paper:
Blanchard-Wrigglesworth, E., M. A. Webster, S. L. Farrell, and C. M. Bitz. "Reconstruction of Snow on Arctic Sea Ice." Journal of Geophysical Research: Oceans (2018).

  • The file snow_depth.nc below contains fields of reconstructed April snow depth (April 1980 to April 2015, note 1988 is NaN because of missing SIC data that winter) as described in the paper.

    The file has 3 variables: reconstructed snow depth, latitude and longitude - 'snow' is on a 36x46x44 (time,x,y) matrix, 'lat' and 'lon' are on 46x44 (x,y) matrices. The reconstruction is on a 75x75km grid as described in the paper. Please contact me at ed at atmos.washington.edu if you have any questions.

  • Below you can also find the weighted Warren snow depth climatology for each year from 2005 to 2015 on the same grid as the snow depth reconstruction above. As in the paper, we take the average March/April Warren snowdepth, and weigh it by ice type, as estimated by the OSISAF ice type dataset (data here: ftp://osisaf.met.no/archive/ice/type/)

    The file has 3 variables: weighted Warren climatological snow depth, latitude and longitude - 'snow_warren' is a 36x46x44 (time,x,y) matrix, 'lat' and 'lon' are 46x44 (x,y) matrices.

  • Figure 1 in the paper. Reconstructed spring snow depth and OIB snow depth in cm for 2009 to 2015. The magenta contours indicate the first year-multiyear ice boundary. The bottom right plot shows the interannual standard deviation of reconstructed snow depth for 2009-2015.
