Sentences with phrase «improving ice sheet models»

«Improving ice sheet models means we need even finer resolution,» Gogineni said.

Not exact matches

Diagnostic modelling can be used to improve the understanding of the processes controlling the behaviour of a particular ice stream, or to study the importance of one or more physical process in an ice sheet in general.

SALSA will gather data from permanent GPS stations to better understand subglacial water flow's influence on the larger ice sheet system and improve subglacial lake modeling through comparing our model's estimates against geochemical data.

Improving digital elevation models over ice sheets using AVHRR - based photoclinometry.

Scientific knowledge input into process based models has much improved, reducing uncertainty of known science for some components of sea - level rise (e.g. steric changes), but when considering other components (e.g. ice melt from ice sheets, terrestrial water contribution) science is still emerging, and uncertainties remain high.

An improved Antarctic dataset for high resolution numerical ice sheet models (ALBMAP v1).

The US CLIVAR Greenland Ice Sheet - Ocean Interactions Working Group was formed to foster and promote interaction between the diverse oceanographic, glaciological, atmospheric and climate communities, including modelers and field and data scientists within each community, interested in glacier / ocean interactions around Greenland, to advance understanding of the process and ultimately improve its representation in climate models.

Reducing these uncertainties by improving models of the processes that cause ice sheets to lose mass is, therefore, a critical goal of Earth Science research.

Despite higher temperature change projections in this assessment, the sea level projections are slightly lower, primarily due to the use of improved models which give a smaller contribution from glaciers and ice sheets.

«All this data is giving us much better insight into how sea ice and the ice sheets are changing, and this will help us understand the processes and improve our models and forecasts,» Meier said.

For their study, Hansen and his colleagues combined ancient paleo - climate data with new satellite readings and an improved model of the climate system to demonstrate that ice sheets can melt at a «non-linear» rate: rather than an incremental melting as Earth's poles inexorably warm, ice sheets might melt at exponential rates, shedding dangerous amounts of mass in a matter of decades, not millennia.

Much process - based research coupling field work, remote sensing, and modeling is required to advance assessment of the likelihood of a threshold - crossing leading to abrupt sea - level rise from the ice sheets, as well as to improve projections of moregradual sea - level rise that could lead to threshold - crossing events in other systems.
