Ozone hole in Antarctica shrinks significantly, but not a record low as erroneously reported elsewhere

While this is good news any way you look at it,  I note there are a number of news reports saying that the “Ozone Hole Shrinks to Record Low” which are non thinking media regurgitations from a LiveScience article by Stepahnie Pappas. Pappas even shows how this isn’t true in her own story, see the…

Why ice loss and sea level measurements via satellite and the new Shepherd et al paper are highly uncertain at the moment

There’s a paper (Shepherd et al) on ice loss and sea level rise that has been making the rounds in media (such as this article in Science Recorder, claiming it validates global warming) that is causing some stir, mainly because it has a powerfully written press release combined with a volume of researchers (47 scientists),…

Earth, with some MSG added

PR 25 2012 – Today, the Spinning Enhanced Visible and Infrared Imager (SEVIRI) instrument on MSG-3 captured its first image of the Earth (August 7th). This demonstrates that Europe’s latest geostationary weather satellite, launched on 5 July, is performing well and is on its way to taking over operational service after six months of commissioning.

'Doppler radar' for solar storm detection

Rice researcher part of team that used Doppler shifts to ID phenomenon; may help predict space weather  HOUSTON – (July 2, 2012) – Doppler measurements that help track storms on Earth may also be useful for understanding storms on the sun. A Rice University astrophysicist is part of an international team that combined Doppler techniques…

30 years of soil moisture imaged from satellite data

From the Vienna University of Technology, a first. A very cool video follows. Since soil moisture is an indicator of evapotranspiration, I’d love to see a closeup around Mount Kilimanjaro, whose ice cap loss is said to be more related to tree loss and loss of evapotranspiration that Al Gore’s claims of global warming. Above:…

Transit of Venus today may reveal the "Mysterious Arc of Venus"

From Dr. Tony Phillips Science at NASA When Venus transits the sun on June 5th and 6th, an armada of spacecraft and ground-based telescopes will be on the lookout for something elusive and, until recently, unexpected: The Arc of Venus. “I was flabbergasted when I first saw it during the 2004 transit,” recalls astronomy professor…

CryoSat repurposed from sea ice to bathymetry

From the European Space Agency: CryoSat goes to sea CryoSat was launched in 2010 to measure sea-ice thickness in the Arctic, but data from the Earth-observing satellite have also been exploited for other studies. High-resolution mapping of the topography of the ocean floor is now being added to the ice mission’s repertoire. The main objective…

ENVISAT declared dead in space

ESA declares end of mission for Envisat From the European Space Agency: PR 15 2012 – Just weeks after celebrating its tenth year in orbit, communication with the Envisat satellite was suddenly lost on 8 April. Following rigorous attempts to re-establish contact and the investigation of failure scenarios, the end of the mission is being…
