Variance processing for stable boundary-layer height estimation using backscatter lidar data: A discussion
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessIn this paper we present a method for estimating the height of the nocturnal stable boundary layer by using lidar measurements and a single radiosonde for unambiguous initial guess. The method relies on the correlation ... -
Floating Doppler Wind Lidar motion simulator for horizontal wind speed measurement error assessment
(Institute of Electrical and Electronics Engineers (IEEE), 2021)
Conference report
Open AccessThis study presents a wind retrieval simulator of a floating Doppler Wind Lidar (DWL) with 6 Degrees of Freedom (DoF) motion. The simulator considers a continuous-wave conical-scanning floating DWL which retrieves the wind ... -
Using several monitoring techniques to measure the rock mass deformation in the Montserrat Massif
(Institute of Physics (IOP), 2015)
Conference lecture
Open AccessMontserrat Mountain is located near Barcelona in Catalonia, at the north-east cornerof Spain, and its massif is formed by conglomerate interleaved by siltstone/sandstone withsteep slopes very prone to rock ... -
The flexible microwave payload -2: design, implementation, and optimization of a GNSS-R and radiometry processor for cubesat-based earth observation missions
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyThe Flexible Microwave Payload 2 (FMPL-2) is a Remote Sensing payload carried on board 3 Cat-5/A, one of the two 6-unit CubeSats of the FSSCat mission. FMPL-2 is a payload based on a Software Defined Radio (SDR), integrating ... -
Precise orbit observation techniques for geosynchronous synthetic aperture radar (GEOSAR)
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyThe orbit accuracy requirements for a Geosynchronous Synthetic Aperture Radar (GEOSAR) are studied. Compared to telecommunication GEO satellites' station keeping needs, focusing the GEOSAR synthetic aperture demands a more ... -
Refining the methodology to correct the faraday rotation angle from SMOS measurements
(Institute of Electrical and Electronics Engineers (IEEE), 2019)
Conference report
Restricted access - publisher's policyIn this work, a refined methodology to correct the Faraday Rotation angle (FRA) for the SMOS mission is proposed. The method is based on calculating the FRA using the SMOS full-pol radiometric data to obtain VTEC maps ... -
Ionospheric scintillation model limitations and impact in GNSS-R missions
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessThe ionosphere impacts radio-wave propagation, notably up to a few GHz. The main applications impacted by the ionosphere are GNSS positioning and timing, Earth Observations (especially low frequency SAR missions e.g. ... -
Interferometry based orbit observation for geosynchronous synthetic aperture radar (GEOSAR) missions
(International Astronautical Federation, 2019)
Conference report
Restricted access - publisher's policyA major limitation of current Low Earth Orbit Synthetic Aperture Radars (LEOSAR) is related to their revisit time of several days or weeks. They cannot provide continuous monitoring over the same area of the planet. The ... -
Synergetic observations by ground-based and space lidar systems and aeronet sun-radiometers: a step to advanced regional monitoring of large scale aerosol changes
(EDP Sciences, 2020)
Conference report
Open AccessThe paper presents the preliminary results of the lidar&radiometer measurement campaign (LRMC-2017), estimation of statistical relations between aerosol mode concentrations retrieved from CALIOP and ground-based lidar ... -
Direct, longwave radiative forcing of mineral dust: improvement of its estimation by means of tools recently developed by the EARLINET community
(EDP Sciences, 2016)
Conference report
Open AccessThe objective of this work is to investigate how the knowledge of the vertically-resolved fine and coarse mode aerosol optical depth modifies the longwave radiative forcing. Since relatively little the EARLINET (European ... -
Radio-frequency interference location, detection and classification using deep neural networks
(Institute of Electrical and Electronics Engineers (IEEE), 2020)
Conference report
Open AccessGlobal Navigation Satellite System (GNSS) signals are used in Earth Observation for Radio Occultation and Reflectometry. The increasing effects of Radio-Frequency Interferences (RFI) on the performance of these receivers ... -
Concept design of a multiwavelength aerosol lidar system with mitigated diattenuation effects and depolarization-measurement capability
(EDP Sciences, 2016)
Conference lecture
Open AccessIt is known that the retrieval of aerosol extinction and backscatter coefficients from lidar data acquired through so-called total-power channels – intended to measure the backscattered power irrespective of the polarization ...
