1. Dynamical aspects of coherent eddies in the North Atlantic Ocean : Insights from Satellite Observations
Sammanfattning : Oceanic mesoscale eddies, often referred to as the “weather of the ocean”, have horizontal scales of O(10) − O(102) kilometers and timescales spanning days to months. These structures comprise a complex system of coherent eddies (meaning they retain their shape and structure over time and space), filaments, and spirals that influence the transport of heat, salt, and nutrients in the ocean.

2. On Satellite Gravity Gradiometry
Sammanfattning : .... LÄS MER
3. The GLAST Satellite Calorimeter
Sammanfattning : The Gamma Ray Large Area Space Telescope (GLAST) is a multi-national satellite mission with aim to study the high-energy gamma ray sky. The main instrument is the Large Area Telescope (LAT) that consists of 16 towers, each housing a silicon strip precision tracker and a CsI(Tl) calorimeter. LÄS MER
4. A Software-Defined Baseband for Satellite Ground Operations : Feasibility and Design
Sammanfattning : Satellite telemetry, tracking, and command (TT&C) is a crucial activity needed to maintainthe health of a spacecraft or sometimes to facilitate payload data download. TT&Cground operations are facilitated by a communication device known in the TT&C communityas a baseband. LÄS MER
5. Satellite measurements and climate modelling of water in the tropical upper troposphere
Sammanfattning : The International Panel on Climate Change (2007) has identified key areas of uncertainty with regards to future climate change, e.g., the upper troposphere. A portion of the uncertain- ties come from climate models and this makes model accuracy very important. LÄS MER
