The discovery of noctilucent (night shining) clouds in 1885 revealed an atmosphere which extended far higher than expected. Since then, these clouds have challenged scientists around the world to find out why they form and vary. Because they scatter solar light, they shimmer at altitudes far above the typical cloud (~51 miles) which makes them… Read more »
A University of Colorado at Boulder research team has discovered the first definitive evidence of shorelines on Mars, an indication of a deep, ancient lake there and a finding with implications for the discovery of past life on the Red Planet. Estimated to be more than 3 billion years old, the lake appears to have… Read more »
6/4/2009 – Observing cloud climate feedbacks in the Earth’s Radiation Budget with the help of blackbodies, the Sun & Moon and ice particles on the edge of space.
Abstract:It is essential to maintain global measurements of the Earth’s Radiation Budget (ERB) from space, which are the scattered solar and emitted thermal radiative fluxes leaving the planet. These are required for purposes of validating current climate model predictions of our planet’s future response to anthropogenic greenhouse gas forcing. The measurement accuracy and calibration stability… Read more »
