Rapidly warming Arctic sea ice -- Implication for the Arctic amplification

Based on the use of analytically-derived “combined Fresnel equation”, which combines two Fresnel equations for polarized reflectivities, we were able to retrieve the ice surface temperature below the snow layer, over the Artic sea ice area. Aimed at retrieving the long-term temperature information over the Arctic sea ice region, we attempted to retrieve the sea ice temperature from 30-year long SSM/I and SSMIS FCDR (Fundamental Climate Data Record) data.

Quantifying the role of local and remote processes in polar amplification

The surface temperature response to greenhouse gas forcing displays a characteristic polar amplification (PA) pattern, particularly in the Northern Hemisphere. The relative importance of individual processes in causing it are still debated. While some studies highlight the importance of the surface albedo feedback, others dispute its dominance and stress larger contributions from long-wave feedbacks, specifically the lapse rate feedback. Additionally, northward atmospheric and oceanic heat transport has been proposed to be important.

Contributions of Radio Occultation to Weather and Climate

Using the world’s most accurate and precise thermometer from space

The launch of the proof-of-concept mission GPS/MET (Global Positioning System/Meteorology) in 1995 began a revolution in profiling Earth’s atmosphere through radio occultation (RO).   The six-satellite constellation, FORMOSAT-3/COSMIC (Formosa Satellite mission #3)/Constellation Observing System for Meteorology, Ionosphere, and Climate), launched in 2006, has proven the theoretical capabilities of RO to provide accurate and precise profiles of electron density in the ionosphere and refractivity, containing information on temperature and water vapor, in the stratosphere and troposphere.

A multi-model analysis of the resolution influence on precipitation climatology in the Gulf Stream region

Using climate simulations from coupled and uncoupled general circulation models, this study investigates the influence of horizontal resolution in both atmospheric and oceanic model components on the mean precipitation over the Gulf Stream (GS) region. For this purpose, three sets of model experiments are analyzed. The first two examine the effects of increasing horizontal resolution of an atmospheric general circulation model (AGCM) gradually from 100 to 10 km under fixed oceanic settings.

The Arctic: A greenhouse gas hotspot?

Vast amounts of organic carbon are stored in Arctic permafrost soils and in the seabed of the Arctic shelves. In a warming world, some of this carbon might be degraded as carbon dioxide or methane and amplify the terrestrial greenhouse effect. How fast and how strong is this climate feedback? Earth System Model simulations predict increasing carbon losses from thawing permafrost during this century. However the global context, Arctic surface-atmosphere fluxes of these gases are currently still very modest.

Rapid Evolutionary Responses to Radical Habitat Change

How can we assess whether populations have the potential to evolve in response to catastrophic environmental change, such as biological invasions, oil spills, or climate change? To what extent are populations constrained from undergoing an evolutionary response? And would independently derived populations show evidence of parallel evolution?
