Planet Earth at 4K
Thanks to the german astronaut Alexander Gerst and his numerous photos taken during his six month journey in space on board of the International Space Station (ISS), ESA released this marvelous time lapse video showing stunning images from our blue planet. During his 166 days on board, he managed to take about 12500 shots in constant intervals, showing snapshots of auroras, sunrises & sunsets, cloud formations, stars, oceans, our Milky Way, lightnings and last but not least our thin and fragile atmosphere.

With over 20000 fatalities and numerous human catastrophes all around the globe over the past year, there is a high demand for a continuous and near-real-time warning system for casualties of natural disasters. With the establishment of the International Charter ‘Space and Major Disasters’ in 1999, all important space agencies agreed on sharing their satellite resources to provide a 24/7 monitoring of natural disasters all over the globe.

In this thesis a performance assessment for the future German-French climate monitoring initiative, Methane Remote Sensing Lidar Mission (MERLIN), proposed by DLR and CNES in 2010 was undertaken. A general space lidar performance issue is the obstruction by optically dense clouds. For this purpose cloud free statistics, the global cloud top flatness and global cloud top distributions were derived from the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation (CALIPSO) level 2, 333 m and 5 km lidar cloud-layer products between 01 January 2007 and 01 January 2008.

The 2003 Bam, Iran earthquake was a major earthquake with a moment magnitude of 6.6, that caused a huge number of casualties as well as major destructions in Bam and the surrounding Kerman province. Due to continous observation from space it is possible to determine the geophysical processes involved not only by classical seismographs but also by Radar interferometry.
