The National Snow and Ice Data Center (NSIDC) announces the release of
Canadian Meteorological Centre (CMC) Daily Snow Depth Analysis Data.

This dataset, provided by Ross Brown and Bruce Brasnett of Environment
Canada, contains a Northern Hemisphere subset of the global daily snow
depth analysis produced by the Canadian Meteorological Centre since
1998. The daily snow depth analyses are based on the optimal
interpolation of real-time snow depth information from surface synoptic
observations, meteorological aviation reports, and special aviation
reports. The dataset also includes monthly mean snow depth and derived
monthly mean snow water equivalent estimated using a monthly mean snow
density look-up table. The dataset covers the period from April 1998
through the end of 2009 and will be updated annually while the
operational analysis is maintained.

  1. New Web Page
    Arctic Sea Ice Volume Anomaly
    Polar Science Center
    University of Washington

Researchers at the University of Washington's Polar Science Center have
created a web page that provides up-to-date Arctic Sea Ice Volume
Anomaly estimates from the Pan-Arctic Ice Ocean Modeling and
Assimilation System (PIOMAS). It is available at:
http://psc.apl.washington.edu/ArcticSeaiceVolume/IceVolume.php.

The purpose of the web page is to visualize recent sea ice volume
changes in the context of longer-term variability. Arctic sea ice volume
is an important indicator of climate change because it accounts for
variations in sea ice thickness as well as sea ice extent. Total arctic
sea ice volume cannot currently be observed continuously. Observations
from satellites, Navy submarines, moorings, and field measurements are
limited in space or time. The assimilation of observations into
numerical models currently provides one way of estimating sea ice volume
changes on a continuing basis. Volume estimates using age of sea ice as
a proxy for ice thickness are another useful method.
