ABSTRACT The impact of large-scale constellations satellites, is a concern for ground-based astronomers. In recent years there has been significant increase in the number satellites low-Earth orbit and this trend set to continue. large increases probability that one will enter field view telescope at right solar angle appear bright enough it can corrupt delicate measurements. We present new too...

Climate models and satellite observations both indicate that the total amount of water in the atmosphere will increase at a rate of 7% per kelvin of surface warming. However, the climate models predict that global precipitation will increase at a much slower rate of 1 to 3% per kelvin. A recent analysis of satellite observations does not support this prediction of a muted response of precipitat...

[1] Clear-sky longwave radiative feedback processes depicted in climate models prepared for the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) are investigated using satellite observations of the clear-sky outgoing longwave radiation (OLR). Estimates of clear-sky longwave radiative damping are derived from regional, seasonal, and interannual sources of variabili...
