Automatic detection of ship tracks in ATSR-2 satellite imagery
Automatic detection ship tracks ATSR-2 satellite imagery
2009/3/31
Ships modify cloud microphysics by adding cloud condensation nuclei (CCN) to a developing or existing cloud. These create lines of larger reflectance in cloud fields that are observed in satellite ima...
Total and partial cloud amount detection during summer 2005 at Westerland（Sylt, Germany）
cloud amount detection summer Westerland
2009/3/13
The detection of cloudiness is investigated by means of partial and total cloud amount estimations from pyrgeometer radiation measurements and visible all-sky imager observations. The measurements hav...
Major solar eruptions (coronal mass ejections) are accompanied by massive ejections of protons. When these charged particles head for the Earth through the interplanetary magnetic field with high flux...
Polar stratospheric cloud observations by MIPAS on ENVISAT: detection method, validation and analysis of the northern hemisphere winter 2002/2003
Polar stratospheric cloud observations MIPAS ENVISAT northern hemisphere winter
2009/2/7
The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) on ENVISAT has made extensive measurements of polar stratospheric clouds (PSCs) in the northern hemisphere winter 2002/2003. A PSC...
