CYMS (Scaling-up Cyclone Monitoring Service with Sentinel-1)

CLS COLLECTE LOCALISATION SATELLITES (FR)

Summary

Tropical Cyclone (TC) observations over the global ocean are a key component in extreme events monitoring and in anticipating appropriate risk mitigation and emergency response at landfall. In particular, the Tropical Cyclone Programme (TCP) of the World Meteorological Organization (WMO), allows tropical cyclone forecasters to access various sources that provide conventional and specialized data/products, including those from Numerical Weather Predictions (NWP) and remote sensing observations, as well as forecasting tools on the development, motion, intensification and wind distribution of tropical cyclones.
The operational delivery of high-resolution TC observations from SAR will significantly help the tropical cyclone forecasters of the six tropical cyclone Regional Specialized Meteorological Centres (RSMCs) and the six Tropical Cyclone Warning Centres (TCWCs) having regional responsibility to provide advisories and bulletins with up-to-date first level basic meteorological information on all tropical cyclones, hurricanes, typhoons everywhere in the world. Moreover, the unique ability of SAR systems to probe high resolution observations of the sea surface from space coupled with a strategy to maximize the acquisitions over TC will allow to start building a new database for science applications.

The first demonstration of the Copernicus Sentinel-1 SAR capabilities was first triggered in 2016 under the SHOC campaigns of the ESA SEOM R&D program. The combination of high resolution and wide swath observations at C-band together with dual-polarization capability offers a unique opportunity to characterize the inner core storm structures. The late programming of S-1 acquisitions by ESA and the high quality of SHOC products has successfully illustrated the potentials of S-1 constellation mission to be part of a dedicated multi-missions hurricane observation strategy, including other sensors such as radiometers (SMOS, SMAP), and third party SAR missions (Radarsat-2, ALOS-2…). Since then, IFREMER and CLS together with ESA/ESRIN have continuously monitored hurricane with S-1 sensors on a best effort basis, while engaging an increasing number of potential end-users and stakeholders and starting several studies for science applications based on this dataset.

The main objective of this proposed project is to scale up this operational service (hereafter called CYMS –CYclone Monitoring service with S-1), in view of its potential integration as part of a Copernicus Service. The service shall provide validated and fully acknowledged products, be consistent, standardized, interoperable and harmonized across international institutions and bodies supporting European policies and the international charter of risk management. The service includes not only NRT operational wind field products, but also an archive center ensuring a continual improvement cycle and full data uptake by stakeholders.
