| Most complete Antarctic map for climate research made public Posted: 18 Aug 2014 05:41 PM PDT A new satellite image of Antarctica has been made available to the public, and the imagery will help scientists all over the world gain new insight into the effects of climate change. Using Synthetic Aperture Radar with multiple polarization modes aboard the RADARSAT-2 satellite, the CSA collected more than 3,150 images of the continent in the autumn of 2008, comprising a single pole-to-coast map covering all of Antarctica. This is the first such map of the area since RADARSAT-1 created one in 1997. |
| Research improves temperature modeling across mountainous landscapes Posted: 18 Aug 2014 01:14 PM PDT New research provides improved computer models for estimating temperature across mountainous landscapes. Accurate, spatially based estimates of historical air temperature within mountainous areas are critical as scientists and land managers look at temperature-driven changes to vegetation, wildlife habitat, wildfire and snowpack. |
| New tool makes online personal data more transparent Posted: 18 Aug 2014 10:51 AM PDT XRay is a new tool that reveals which data in a web account, such as emails, searches, or viewed products, are being used to target which outputs, such as ads, recommended products, or prices. Determined to provide checks and balances on data abuse, XRay is designed to be the first fine-grained, scalable personal data tracking system for the web. |
