Improved global sea surface height and current maps from remote sensing and in situ observations [PDF]

open access: yesEarth System Science Data, 2023
We present a new gridded sea surface height and current dataset produced by combining observations from nadir altimeters and drifting buoys. This product is based on a multiscale and multivariate mapping approach that offers the possibility to improve ...

Copernicus Sea Level Space Observations: A Basis for Assessing Mitigation and Developing Adaptation Strategies to Sea Level Rise

open access: yesFrontiers in Marine Science, 2021
It is essential to monitor accurately current sea level changes to better understand and project future sea level rise (SLR). This is the basis to support the design of adaptation strategies to climate change.

Satellite RNAs and Satellite Viruses of Plants [PDF]

open access: yesViruses, 2009
The view that satellite RNAs (satRNAs) and satellite viruses are purely molecular parasites of their cognate helper viruses has changed. The molecular mechanisms underlying the synergistic and/or antagonistic interactions among satRNAs/satellite viruses, helper viruses, and host plants are beginning to be comprehended. This review aims to summarize the

Autonomous control of a reconfigurable constellation of satellites on geostationary orbit with artificial potential fields [PDF]

open access: yes, 2012
This paper presents a method of controlling a constellation of small satellites in Geostationary Earth Orbit (GEO) such that the constellation is able to reconfigure - changing the angular position of its members relative to the Earth’s surface in order ...

Assessment of the EUMETSAT Multi Decadal Land Surface Albedo Data Record from Meteosat Observations

open access: yesRemote Sensing, 2021
Surface albedo, defined as the ratio of the surface-reflected irradiance to the incident irradiance, is one of the parameters driving the Earth energy budget and it is for this reason an essential variable in climate studies. Instruments on geostationary

Satellite RNAs and Satellite Viruses [PDF]

open access: yesMolecular Plant-Microbe Interactions®, 2016
Satellite RNAs and satellite viruses are extraviral components that can affect either the pathogenicity, the accumulation, or both of their associated viruses while themselves being dependent on the associated viruses as helper viruses for their infection. Most of these satellite RNAs are noncoding RNAs, and in many cases, have been shown to alter the

Spectral Synthesis for Satellite-to-Satellite Translation

open access: yesCoRR, 2020
Earth observing satellites carrying multi-spectral sensors are widely used to monitor the physical and biological states of the atmosphere, land, and oceans. These satellites have different vantage points above the earth and different spectral imaging bands resulting in inconsistent imagery from one to another.
