Sentences with phrase «ice concentration threshold»

However, this year we are using a revised ice age product, one based on a 15 % sea ice concentration threshold rather than the earlier version, which used a threshold of 40 % [see Maslanik et al., in review for more details].

The ice age product is based on a 15 % sea ice concentration threshold to be consistent with the threshold used for mapping overall sea ice extent.

Not exact matches

A threshold h applied on the (thickness Feb = Mar concentration Sept) field yields the predicted September extent after the regression with the past four years of sea ice extent observations.

The BRT then manufactured an untested sea - ice threshold based solely on circumstantial evidence to assert whelping and nursing required sea ice concentrations over 25 %.

Usually, scientists define a threshold of minimum concentration to mark the ice edge; the most common cutoff is at 15 percent.

The use of a 15 % threshold on sea ice concentration captures greater detail within the marginal ice zone, matches NSIDC's threshold used for mapping overall sea ice extent and should therefore provide a better estimate of the September 2011 ice extent.
