Clusters of four or more small satellites could look at a single location on Earth from multiple angles, and measure that location's total reflectance with an error that is half that of single satellites in operation today, an MIT-led study suggests.

Settled Science: Clusters of small satellites could help estimate Earth’s reflected energy

From M.I.T. and the “Total outgoing radiation is actually one of the biggest uncertainties in climate change” department: Batches of shoebox-sized satellites could improve estimates of Earth’s reflected energy A team of small, shoebox-sized satellites, flying in formation around the Earth, could estimate the planet’s reflected energy with twice the accuracy of traditional monolith satellites,…

The Size of Icy Reflections

Guest Post by Willis Eschenbach In my continuing wanderings through the regions cryospherical, I find more side roads than main highways. In my last two posts here and here, I discussed the curious inverse relationship between temperature and ice accumulation rates in Greenland and Antarctica. Wanting to understand the changes in the polar oceans that occur when…

Another alarmist pillar collapses – Greenland melting due to old soot feedback loops and albedo change – not AGW

From the EARTH INSTITUTE AT COLUMBIA UNIVERSITY and the “we told you so time and again at WUWT” department comes this study which not only explains the “insta-melt” in the Summer of 2012, but the ongoing melting that has been incorrectly blamed on CO2, when instead it’s all about older soot embedded in snow coming…

No surprise here: Jet contrails affect surface temperatures

From Penn State High in the sky where the cirrus ice crystal clouds form, jet contrails draw their crisscross patterns. Now researchers have found that these elevated ice cloud trails can influence temperatures on the ground and affect local climate, according to a team of Penn State geographers. Video follows. “Research done regarding September 2001,…
