Sentences with phrase «ice thickness field»

Zhang and Lindsay, 4.60 (4.00 - 5.20), Modeling Our seasonal prediction focuses not only on the total Arctic sea ice extent, but also on sea ice thickness field and ice edge location.

Zhang and Lindsay, 5.1 (± 0.4), Modeling Our seasonal prediction focuses not only on the total Arctic sea ice extent and ice concentration field, but also on ice thickness field and ice edge location.

Zhang, 5.1 (+ / - 0.6), Modeling The seasonal prediction focuses not only on the total Arctic sea ice extent, but also on sea ice thickness field and ice edge location.

Ice - ocean model simulations, on the other hand, have requirements with respect to data density and quality, e.g., for observed ice thickness fields used in initialization of model runs, that are currently not being met by existing data sources (with the exception of, e.g., satellite - observed ice concentration fields).

While a detailed evaluation will be forthcoming, the lack of high - resolution ice thickness fields in this topographically complicated region hampers such simulations.

Not exact matches

The team, which Marc led and provided the logistical support for, deployed from Resolute to Nord Greenland before setting up a rustic field camp on the sea ice for six days, during which time we mechanically drilled the ice to measure thickness, measuring snow depth in a grid pattern along the flight lines as well as dragging instruments along the surface that produced the same measurements for comparison to the airborne data.

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.

Over the sea ice field the observations include: sea ice freeboard height and hence sea ice thickness from radar altimetry; sea ice surface temperature and sea ice drift from respectively infrared radiometer and imaging spectrometer under cloud free conditions.

Field observations summarized in the contribution by Hutchings and discussed in this month's Regional Outlook indicate that starting ice thicknesses were comparable to last year in the Beaufort and Chukchi Seas, and that after getting off to a fast start, melt has slowed down considerably, resulting in below - normal melt rates.

The ice - ocean model is initialized with satellite estimates of ice concentration and model simulated ice thickness and ocean fields and is forced by the atmospheric fields from 2003 to 2009.

The ensemble consists of seven members each of which uses a unique set of NCEP / NCAR atmospheric forcing fields from recent years, representing recent climate, such that ensemble member 1 uses 2005 NCEP / NCAR forcing, member 2 uses 2006 forcing..., and member 7 uses 2011 forcing... In addition, the recently available IceBridge and helicopter - based electromagnetic (HEM) ice thickness quicklook data are assimilated into the initial 12 - category sea ice thickness distribution fields in order to improve the initial conditions for the predictions.

Any field - or ship - based updates on ice conditions in the different regions such as sea ice morphology (e.g., concentration, ice type, floe size, thickness, snow cover, melt pond characteristics, topography), meteorology (surface measurements) and oceanography (e.g., temperature, salinity, upper ocean temperature).

This month's Outlook reports also include a more detailed discussion of sea ice thickness information provided from field measurements and model results.
