An Extended Kalman Filter Framework for Polarimetric X-Band Weather Radar Data Processing

The different quantities measured by dual-polarization radar systems are closely linked to each other. An extended Kalman filter framework is proposed in order to make use of constraints on individual radar observables that are induced by these relations. ...

MEMS Inertial Sensor to Measure the Gravity Gradient Torque in Orbit

Kaustav Ghose

Since the dawn of the Space Age, over six thousand satellites have been launched into Earth orbit. The function of determining the orientation of a satellite in orbit, so that it can point its antennas and instruments in the required direction is known as ...

Practical algorithms for gathering stored correlated data in a network

Ramin Khalili

Many sensing systems remotely monitor/measure an environment at several sites, and then report these observations to a central site. We propose and investigate several practical algorithms for joint routing and compression of data files as they are forward ...

Determination of the Thermal Roughness Length for a Built Environment

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau

In this study, the scalar roughness for sensible heat in the temperature profile (z0,h) is determined based on direct skin temperature measurements and profiles of wind and temperature in a complex urban environment. Typically, skin temperatures are inferr ...

Determination of Thermal Roughness Length for Complex Urban Areas with High Resolution Meteorological Stations

Martin Vetterli, Marc Parlange, Guillermo Barrenetxea Kobas, Daniel Nadeau, Olivier Couach

In this study, we determine the scalar roughness for sensible heat in the temperature profile (z0,h) based on direct skin temperature measurements and profiles of wind and temperature in a complex urban environment. Classically, skin temperatures are infer ...
