Long-term Measurements of Nighttime LF Radio Wave Reflection Heights over Central Europe

Quality of Long-term Satellite Wind and Wave Measurements

Since the time of the first data from ERS-1, in 1991, the french Processing and Archiving Facility CERSAT in IFREMER Département d’Océanographie Spatiale has processed and distributed data from ERS-1 and ERS2. Concurrently the Département was involved in algorithm development and geophysical validation of the products of ERS altimeters and AMI’s, and then of other satellites, like TOPEX, NSCAT ...

Effect of Nonlinear Phase Variation in Optical Millimetre Wave Radio over Fibre Systems

In this paper, we propose an optical millimetre wave radio-over-fibre (mm-wave RoF) system that uses a dual drive Mach Zehnder modulator (DD-MZM), which is biased at the maximum transmission biasing point, to generate an optical double sideband-suppressed carrier. The input to the DD-MZM are binary phase shift keying (BPSK), quadrature phase shift keying (QPSK), 8-phase shift keying (8-PSK) and...

Validating MODIS land surface temperature products using long-term nighttime ground measurements

The Moderate Resolution Imaging Spectroradiometer (MODIS), onboard the NASA Terra and Aqua Earth Observing System satellites, provides multiple land surface temperature (LST) products on a daily basis. However, these products have not been adequately validated. This paper presents preliminary results of validating two MODIS Terra daily LST products, MOD11_L2 (version 4) and MOD07_L2 (version 4)...

Developing an Electron Density Profiler over Europe Based on Space Radio Occultation Measurements

This paper presents the development of an Artificial Neural Network electron density profiler based on electron density profiles collected from radio occultation (RO) measurements from LEO (Low Earth Orbit) satellites to improve the spatial and temporal modeling of ionospheric electron density over Europe. The significance in the accurate determination of the electron density profile lies on th...
