Fifth Space for Hydrology Workshop (Hydrospace 2023)

Fri, 16 Jun 2023 07:58:02 +0000

The European Space Agency, in the context of the "Earth Observations Science for Society" Programme, the Centre National d'Ãtudes Spatiales (Cnes) and the Global Energy and Water EXchanges project (Gewex) of the World Climate Research Programme are organising a sequel joint event to Hydrospace2021 and EO4Water 2020: The 5th Space for Water Cycle and Hydrology Workshop, Hydrospace 2023.
Hydrospace 2023 aims at reviewing the latest advances in the use of Earth Observation (EO) technology for water cycle science, hydrology and its applications, exploring the potential offered by the existing and coming EO satellites together with advanced modelling, in situ data and novel technologies, as well as the main challenges and opportunities to enhance our current capacity to observe, understand and predict the water cycle, and its impacts and feedback with human activities and ecosystems.
The ultimate target of the event is to review the state of the art and latest developments in EO for water research and hydrology and contribute to define a community scientific agenda for the coming few years, which will drive future scientific activities of ESA, other space agencies and partners to face some of the main societal challenges of our time.
The Hydrospace 2023 Workshop is open to EO scientists, water researchers and students, modellers, Earth system and climate scientists, industry, operational agencies, policy makers, representatives of local communities and other stakeholders interested in sharing their knowledge and experience and in contributing to drive the scientific agenda for advancing EO water research and future applications.
No participation fees will be charged. Participants are expected to finance their own travel and accommodation expenses. The working language of the workshop is English.

Call for articles for a Special Issue of Remote Sensing on Altimetry Cal/Val

Fri, 25 Oct 2019 16:25:27 +0000

Satellite-borne radar altimeters have been making measurements of sea level, wave height and surface roughness for several decades, so the principles of conventional marine altimetry are very mature. The adoption of wider parts of the electromagnetic spectrum (lasers, as well as Ka-, Ku - C- and S-band radars) and the development of new technologies (delay Doppler altimetry, interferometric altimetry, bistatic altimetry and swath instruments) offer new opportunities and new challenges. Improved tracking capabilities have led to applications in the coastal zone, in the cryosphere, over land and over inland waters. As each domain has different surface properties, retrackers need to be developed for the particular waveforms, and each of these requires separate assessment. Where these domains meet, there is the additional complication of ensuring consistency. Each instrument requires dedicated effort to understand and minimise instrumental, measurement, and processing errors, and to harmonise the data coming from multiple altimeter missions such that multiinstrument gridded ocean products can be constructed. Coupled with this is the need to develop and monitor ancillary measurements and corrections, such as orbits and atmospheric path delays derived from models or microwave radiometry. This Special Issue will address all aspects of improving and verifying the accuracy, stability and consistency of conventional and new altimetric datasets over all domains. https://www.mdpi.com/journal/remotesensing/special_issues/alt_calval

Michel Lefebvre passed away on July 21st, 2019

Wed, 24 Jul 2019 12:05:57 +0000

Michel Lefebvre passed away on July 21st, 2019. Captain of the merchant navy, astronomer, geodesist, driving force, inspiring person, human being and literary man, he has been and was all that and more.

He was one of the pioneer of satellite radar altimetry, promoting the French project "PosÃ©idon", and collaborating with the US "TOPEX" project in the 1980s to merge them into 'Topex/Poseidon'. He was instrumental in the success of the mission, of the collaboration between the countries, but also of the collaboration between engineers, scientists and end-users of the data.

This success continued, is continuing and will continue with Jason-1, 2, 3 and soon -CS, but also with the other satellite altimetry missions, including SWOT. He also launched Aviso with Topex/Poseidon, to put into music the ocean data as he wrote in the first Aviso Newsletter.
Even after retiring, he kept an eye and an interest on the altimetry and operational oceanography fields and new developments, often contacting people to have news of the satellites and of the different research and uses done with the data.
His friends and co-workers remember him with respect and admiration. He will be missed by all.

Visual presentation of the ODATIS Ocean Cluster

Mon, 15 Oct 2018 09:41:00 +0000

ODATIS, Ocean Data Information and Services, serves as the entry point to access all French Ocean observation data. Its general objective is to promote and facilitate the use of ocean observations sampled by way of in situ and remote sensing measurements. ODATIS contributes to describing, quantifying and understanding the ocean as a whole â offshore and coastal â with regard to aspects such as the dynamics and thermodynamics of the ocean, the evolution of its physico-chemical properties, biogeochemical cycles, the operation of marine ecosystems, the evolution of the ocean and the ocean-climate relationship in the past.
