This dataset relates to long-term change and variability in annual timings of sea ice advance, retreat and resultant ice season duration in East Antarctica derived from the satellite passive-microwave time series dating back to Nimbus 7. These were calculated from satellite-derived ice concentration data for the period 1979/80 to 2009/10. The dataset includes more detailed analysis of change and v

This dataset contains data relating to an experimental method in which sea-ice samples were measured in an S-band microwave waveguide. This was conducted as a part of the 2012 SIPEX 2 (Sea Ice Physics and Ecosystems EXperiment) marine science voyage. A specially designed waveguide apparatus was connected to an Agilent FieldFox Portable Network Analyzer. Small parallelopipeds (7 cm X 3 cm X 1.9 cm)

Clouds and their radiative effects have very large uncertainties in present climate models and their quantification continues to be a challenge. The inadequate representation of clouds and moist convection in climate models is the main limitation in current representations of the climate system. Large biases in shortwave radiation and sea surface temperatures in the Southern Ocean are characterist

This dataset contains sea ice surface brightness temperatures using a portable passive-microwave radiometer operating at 36Ghz-H,V mounted to the undercarriage of a Squirrel helicopter during SIPEX 2, 2012. This radiometer is the same sensor as satellite passive-microwave radiometer AMSR-E and AMSR2. Our passive-microwave radiometer is launched on the same helicopter as Jan Lieser's (RAPPAL), so p

The Met Office C-130 research aircraft was based at Windhoek, Namibia between September 5-16, 2000, where it conducted a series of flights over Namibia as part of the SAFARI 2000 Dry Season Aircraft Campaign.The effects of atmospheric aerosols on the Earth's radiation balance are known to be very important, but for many types of aerosols these effects are still poorly understood. In particular, ae

The First ISCCP Regional Experiments (FIRE) have been designed to improve data products and cloud/radiation parameterizations used in general circulation models (GCMs). Specifically, the goals of FIRE are (1) to improve the basic understanding of the interaction of physical processes in determining life cycles of cirrus and marine stratocumulus systems and the radiative properties of these clouds

The surface meteorological data collected at the BOREAS tower and ancillary sites are being used as inputs to an energy balance model to monitor the amount of snow storage in the boreal forest region. The BOREAS HYD-02 team used snow water equivalent (SWE) derived from an energy balance model and in situ observed SWE to compare the SWE inferred from airborne and spaceborne microwave data, and to a

The Antarctic Planetary Boundary Layer (PBL) plays a crucial role in connecting the atmospheric, the oceanic, and cryospheric components of the Antarctic climatic system. The knowledge of the Antarctic PBL is still poor in terms of theoretical understanding as well as in terms of available data. The annual radiative balance is negative and therefore the air layer close to the surface is cooled for
