GNSS-R Altimetry Performance Analysis for the GEROS Experiment on Board the International Space Station

open access: yesSensors, 2017
The GEROS-ISS (GNSS rEflectometry, Radio Occultation and Scatterometry onboard International Space Station) is an innovative experiment for climate research, proposed in 2011 within a call of the European Space Agency (ESA).

Coastal Altimetry Products in the Strait of Gibraltar [PDF]

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2016
This paper analyzes the availability and accuracy of coastal altimetry sea level products in the Strait of Gibraltar. All possible repeats of two sections of the Envisat and AltiKa ground-tracks were used in the eastern and western portions of the strait.

Assessing altimetry close to the coast [PDF]

open access: yes, 2017
Radar altimetry provides measurements of sea surface elevation, wind speed and wave height, which are used operationally by many agencies and businesses, as well as for scientific research to understand the changes in the ocean-atmosphere interface. For

Increasing urban flash flood risk attributable to both climate and development

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
A new event impact attribution methodology that combines convection‐permitting climate model data with flood inundation modelling was used for a five‐hour flash‐flooding event in the suburbs of Leeds in 2014. The results show increased urban flood extent due to both climate change (+16%) and increased urbanisation (+29%).

MORPHOMETRIC ASPECTS IN THE BÂRLAD BASIN [PDF]

open access: yesAerul şi Apa: Componente ale Mediului, 2015
Bârlad valley morphometry is strongly influenced by lithology, geological structure and climatic conditions. Between its springs and the outflow we noticed notable deviations from valley monocline structure and from the consecvent overall direction of ...

Increased Ice Thinning over Svalbard Measured by ICESat/ICESat-2 Laser Altimetry

open access: yesRemote Sensing, 2021
A decade-long pronounced increase in temperatures in the Arctic, especially in the Barents Sea region, resulted in a global warming hotspot over Svalbard. Associated changes in the cryosphere are the consequence and lead to a demand for monitoring of the

Deep Reinforcement Learning Based Autonomous Decision‐Making for Cooperative Uncrewed Aerial Vehicles: A Search and Rescue Real World Application

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT This paper presents the first end‐to‐end framework that combines guidance, navigation, and centralized task allocation for multiple UAVs performing autonomous search‐and‐rescue (SAR) in GNSS‐denied indoor environments. A twin delayed deep deterministic policy gradient controller is trained with an artificial potential field (APF) reward that ...

APPLICABILITY OF 10Hz SATELLITE ALTIMETRY DATA TO THE ANTARCTIC MARGIN [PDF]

open access: yes, 1997
P(論文)Since the declassification of the Geosat Geodetic Mission (Geosat/GM), cross-track resolution of satellite altimeter profiles has improved remarkably. Consequently, the cross-track resolution somewhat exceeds the along-track resolution.
