Development of a sea-ice tank system for measuring microwave properties of sea ice

open access: yesJournal of Glaciology
An outdoor sea-ice tank system for measuring the microwave properties of sea ice has been developed. With the natural cooling and the help of a cooling unit in the movable roof attached to the tank, the system can grow sea ice to about 50 cm thickness ...

Empirical sea ice thickness retrieval during the freeze-up period from SMOS high incident angle observations [PDF]

open access: yesThe Cryosphere, 2014
Sea ice thickness information is important for sea ice modelling and ship operations. Here a method to detect the thickness of sea ice up to 50 cm during the freeze-up season based on high incidence angle observations of the Soil Moisture and ...

Improving the WRF model's (version 3.6.1) simulation over sea ice surface through coupling with a complex thermodynamic sea ice model (HIGHTSI) [PDF]

open access: yesGeoscientific Model Development, 2016
Sea ice plays an important role in the air–ice–ocean interaction, but it is often represented simply in many regional atmospheric models. The Noah sea ice scheme, which is the only option in the current Weather Research and Forecasting (WRF) model ...

Recent summer sea ice thickness surveys in Fram Strait and associated ice volume fluxes [PDF]

open access: yesThe Cryosphere, 2016
Fram Strait is the main gateway for sea ice export out of the Arctic Ocean, and therefore observations there give insight into the composition and properties of Arctic sea ice in general and how it varies over time.

Spatiotemporal Variation Characteristics and Drivers of Winter Arctic Sea Ice Thickness Under the New Arctic Regime

open access: yesJournal of Marine Science and Engineering
The “New Arctic” regime represents a prominent climatic feature of the Arctic Ocean under global warming, characterized by persistently low summer sea ice extent, a marked reduction in sea ice thickness, and an expansion of open water areas at high ...

Better constraints on the sea-ice state using global sea-ice data assimilation [PDF]

open access: yesGeoscientific Model Development, 2012
Short-term and decadal sea-ice prediction systems need a realistic initial state, generally obtained using ice–ocean model simulations with data assimilation. However, only sea-ice concentration and velocity data are currently assimilated.

Discrimination Algorithm and Procedure of Snow Depth and Sea Ice Thickness Determination Using Measurements of the Vertical Ice Temperature Profile by the Ice-Tethered Buoys

open access: yesSensors, 2018
Snow depth and sea ice thickness in the Polar Regions are significant indicators of climate change and have been measured over several decades by ice-tethered buoys.

Evaluation of the ArcIOPS sea ice forecasts during 2021–2023

open access: yesFrontiers in Earth Science
The operational sea ice forecasts from the Arctic Ice Ocean Prediction System (ArcIOPS) during 2021–2023 are validated against satellite-retrieved sea ice concentration and drift data, in situ and reanalyzed sea ice thickness data.

Impacts of Sea Ice Thickness Initialization on Seasonal Arctic Sea Ice Predictions

open access: yesJournal of Climate, 2017
Abstract A promising means for increasing skill of seasonal predictions of Arctic sea ice is improving sea ice thickness (SIT) initial conditions; however, sparse SIT observations limit this potential. Using the Canadian Climate Model, version 3 (CanCM3), three statistical models designed to estimate SIT fields for initialization in a ...
