Titre : Special issue - Advanced global navigation satellite systems tropospheric products for monitoring severe weather events and climate (GNSS4SWEC) Type de document : Périodique Auteurs : G. Vaughan, Éditeur scientifique ; Jonathan Jones, Éditeur scientifique ; Siebren de Haan, Éditeur scientifique ; Eric Pottiaux, Éditeur scientifique ; Olivier Bock Année de publication : 2020 Note générale : Special issue jointly organized between Atmospheric Measurement Techniques, Atmospheric Chemistry and Physics, and Annales Geophysicae Langues : Anglais (eng) Résumé : (auteur) Since 1990, signals from global positioning system (GPS) satellites have been recorded by networks worldwide. From these GPS observations the zenith total delay (ZTD) can be computed. Using surface measurements of pressure and temperature, these ZTD values can be turned into water vapour amount and used for atmospheric research. The main aim of the COST action ES1206 “Advanced Global Navigation Satellite Systems tropospheric products for monitoring severe weather events and climate” (GNSS4SWEC) is to coordinate the research and the development of new, advanced tropospheric products derived from GNSS signal delays, exploiting the full potential of multi-GNSS (GPS, GLONASS and Galileo) water vapour estimates on a wide range of temporal and spatial scales, from real-time monitoring and forecasting of severe weather to climate research. The potential impacts of this work are great: improved severe weather forecasting, leading to a decreased risk to life and national infrastructure; improvement of climate projections also has major global significance. In addition the action will promote the use of meteorological data in GNSS positioning, navigation, and timing services. The main topics envisioned in the special issue include the following:
** The development of advanced and new GNSS tropospheric products related to multi-GNSS constellation signals for water vapour remote sensing, water vapour anisotropy (horizontal gradients, satellite slant delays, tomography, etc.), real-time/ultra-fast water vapour remote sensing in support of nowcasting, improvement of the temporal and spatial resolution capability of GNSS water vapour remote sensing.
** The exploitation of these products in numerical weather prediction (NWP) and nowcasting, such as the development of new initialization/assimilation methods in NWP, the development of forecasting tools (water vapour maps, convective indexes, alarm systems, etc.) for nowcasting and severe weather events.
** The assessment of these GNSS tropospheric products (see first point) derived from a common benchmark reference data set.
** The assessment of the standardized methods/tools for NWP/nowcasting (see second point) based on the GNSS products built on the benchmark data set.
** Exploiting re-analysed/reprocessed GNSS tropospheric products for climate studies: comparison/assimilation in the regional/ global climate models, comparisons with other in-situ, ground-based and satellite water vapour retrievals, development and assessment of homogenization methods for GNSS-based product time series, analysing the variability and trends in GNSS-based water vapour retrievals.
** Establishment of new GNSS analysis centres for monitoring the atmosphere.
Submissions of papers dealing with broader GNSS4SWEC objectives are also encouraged: synergy between GNSS and GNSS radio occultation (RO), monitoring the other components of the hydrological cycle (soil moisture, snow cover, terrestrial water storage) with GNSS.Numéro de notice : sans Affiliation des auteurs : UMR IPGP-Géod+Ext (2020- ) Nature : Numéro de périodique En ligne : https://acp.copernicus.org/articles/special_issue400_89.html Format de la ressource électronique : URL bulletin Permalink : https://documentation.ensg.eu/index.php?lvl=bulletin_display&id=34331 [n° ou bulletin]Advanced GNSS tropospheric products for monitoring severe weather events and climate / Jonathan Jones (2020)

COST Action ES1206, Advanced GNSS Tropospheric Products for Severe Weather Events and Climate (GNSS4SWEC), was a 4-year project, running from 2013 to 2017, which coordinated new and improved capabilities from concurrent developments in GNSS, meteorological and climate communities. For the first time, the synergy of multi-GNSS constellations was used to develop new, more advanced tropospheric products, exploiting the full potential of multi-GNSS on a wide range of temporal and spatial scales - from real-time products monitoring and forecasting severe weather, to the highest quality post-processed products suitable for climate research. The Action also promoted the use of meteorological data as an input to real-time GNSS positioning, navigation, and timing services and has stimulated knowledge and data transfer throughout Europe and beyond.

Aside from these well-known civilian and commercial applications, GNSS is now an established atmospheric observing system, which can accurately sense water vapour, the most abundant greenhouse gas, accounting for 60–70% of atmospheric warming. In Europe, the application of GNSS in meteorology started roughly two decades ago, and today it is a well-established field in both research and operation. This review covers the state of the art in GNSS meteorology in Europe. The advances in GNSS processing for derivation of tropospheric products, application of GNSS tropospheric products in operational weather prediction and application of GNSS tropospheric products for climate monitoring are discussed. The GNSS processing techniques and tropospheric products are reviewed. A summary of the use of the products for validation and impact studies with operational numerical weather prediction (NWP) models as well as very short weather prediction (nowcasting) case studies is given. Climate research with GNSSs is an emerging field of research, but the studies so far have been limited to comparison with climate models and derivation of trends. More than 15 years of GNSS meteorology in Europe has already achieved outstanding cooperation between the atmospheric and geodetic communities. It is now feasible to develop next-generation GNSS tropospheric products and applications that can enhance the quality of weather forecasts and climate monitoring. This work is carried out within COST Action ES1206 advanced global navigation satellite systems tropospheric products for monitoring severe weather events and climate (GNSS4SWEC, http://gnss4swec.knmi.nl).

Aside from these well-known civilian and commercial applications, GNSS is now an established atmospheric observing system which can accurately sense water vapour, the most abundant greenhouse gas, accounting for 60-70 % of atmospheric warming. Water vapour is under-sampled in the current meteorological and climate observing systems, obtaining and exploiting more high-quality humidity observations is essential to weather forecasting and climate monitoring. The European COST Action ES1206 ”Advanced Global Navigation Satellite Systems tropospheric products for monitoring severe weather events and climate (GNSS4SWEC)” will address new and improved capabilities from concurrent developments in both the GNSS and the meteorological communities. For the first time, the synergy of the three GNSS systems (GPS, GLONASS and Galileo) will be used to develop new, advanced tropospheric products, exploiting the full potential of multi-GNSS water vapour estimates on a wide range of temporal and spatial scales, from real-time monitoring and forecasting of severe weather, to climate research. In addition, the COST Action ES1206 will promote the use of meteorological data in GNSS positioning, navigation, and timing services and it will stimulate knowledge transfer and data sharing throughout Europe.
