Korevaar, C.W. (author), Boschma, J.J. (author), den Breeje, R. (author), Ebert, J. (author)Optical feeder links (OFLs) benefit from the vast amount of bandwidth available in the THz-regime of the electro-magnetic spectrum, and could enable future terabit-per-second satellite systems. This study assesses the end-to-end performance of analog coherent OFLs for digital video broadcasting (DVB) applications, employing phase modulation (PM)...conference paper 2022

Jin, J. (author), Segers, A.J. (author), Heemink, A. (author), Yoshida, M. (author), Han, W. (author), Lin, H.X. (author)Aerosol optical depths (AODs) from the new Himawari-8 satellite instrument have been assimilated in a dust simulation model over East Asia. This advanced geostationary instrument is capable of monitoring the East Asian dust storms which usually have great spatial and temporal variability. The quality of the data has been verified through a...article 2019

(author), TNO Bouw en Ondergrond (author)Monitoring aerosols over wide areas is important for the assessment of the population's exposure to health relevant particulate matter (PM). Satellite observations of aerosol optical depth (AOD) can contribute to the improvement of highly needed analyzed and forecasted distributions of PM when combined with a model and ground-based observations....article 2009

Bennouna, Y.S. (author), de Leeuw, G. (author), TNO Bouw en Ondergrond (author)In order to investigate the high temporal variability of aerosols properties over large areas, we are proposing to use geostationary observations from the Spinning Enhanced Visible Infrared Radiometer (SEVIRI) aboard the Meteosat Second Generation satellite (MSG). The algorithm described in this contribution is used to derive daytime Aerosol...conference paper 2007

(author)A Refocusing Mechanism (REM) has been designed and built for the SEVIRI instrument, the imager in the Meteosat Second Generation (MSG) satellite. The purpose of the mechanism is in-orbit focal adjustment of a mirror assembly which forms part of SEVIRI. As the MSG satellite observes the earth and its atmosphere from its geostationary orbit, the...conference paper 1998
