EUMETSAT's role in Copernicus and contribution to CAMS

CAMS General Assembly, Athens 14 June 2016 2

The Copernicus Programme at EUMETSAT

• The Copernicus tasks entrusted to EUMETSAT by the European Commission under the DA are organised in building blocks, including three main building blocks covering operations of Copernicus dedicated missions by EUMETSAT and delivery of Copernicus data and product services from these missions and from Contributing and third party missions.

Provision of AOD and FRP from S-3


Status of Copernicus activities at EUMETSAT

• Activities implemented as per 2015 Work Programme, with some activities postponed to 2016 as a result of J-3 & S-3A launch delays. The 2017 work plan has been released to EC and under EC approval process;

• Successful Jason-3 and Sentinel-3 launches. With Jason-3 OGDR data dissemination to trial users started;

• Approval given by the EC to the Sentinel-3 AOD and FRP products, with expected operational start of service in 2017;

• Regular Bilateral Commission-EUMETSAT management meetings are proving effective along with regular attendance at Programme Committee and User Forum meetings;

• EC has signed data access agreements with the US and Australia, with other countries under discussion. EUMETSAT is finalising Technical Operating Agreements (TOA) with NOAA and CSIRO to cover the technical arrangements for dissemination of Sentinel-3 data

• The spatial resolution will be significantly improved compared to previous missions (~ 7 x 7 km at SSP), which is important to support development of air quality applications

• Sentinel-5 level 1 and 2 products will be produced operationally by EUMETSAT

• Launch of EPS-SG 2021/22

• Geophysical parameters/type mapping of products delivered by the EUMETSAT Copernicus Atmosphere Data Service to the satellites/missions, instruments or set of instruments, and timeliness of the corresponding products


End–to–end services supporting Atmosphere Monitoring Service: Sentinel-5p, Sentinel-3

• Further to EC's request, EUMETSAT is currently assessing the dissemination of S-5P NRT data using EUMETCast (push) as a complementary operational data service delivery

• There are currently no Sentinel-3 atmosphere products delivered• Two products implemented in the future for Aerosol Optical Depth (AOD) and the Fire

Radiative Power (FRP) from SLSTR• EUMETSAT to generate and deliver the atmospheric NRT products while ESA to

generate and disseminate corresponding off-line products. Both NRT products will be derived from SLSTR L1B products, while the off-line AOD product will be based on SLSTR and OLCI L1B

• All EUMETSAT data access services will be used to distribute NRT AOD and FRP products (Data Centre for the on-demand distribution of these products)

• Approval given by EC to AOD and FRP, PDR Aug/Sep 2016, CDR Oct/Nov 2016, FAR May 2017 (AOD) and Mar 2017 (FRP) Final Delivery FAR+1m


Third-Party Data in Support of the Copernicus Atmosphere Service• All S-NPP products listed are already being delivered to

Copernicus users• The same considerations regarding

the requirements on the S-NPP products apply for marine and atmosphere services

• S-NPP Copernicus data services depend on infrastructure support functions and services that are not under the control of EUMETSAT but NOAA

• The target value for the relative (i.e. EUM only) availability set to 99.5% and 15 minutes respectively


NOAA OMPS/VIIRS Data Request and Status

• Receiving OMPS Nadir Profiles in BUFR• Receiving OMPS Total Column EDRs (in BUFR)• Ongoing discussion on a dedicated "volcanic ash" product from OMPS• Recommended use of OMPS INCTO products for now; source for BUFR Total Column

Ozone Map products• Current operational OMPS products are still from the Multiple Triplet algorithm. They

include an Absorbing Aerosol Index and an SO2 Index. SO2 Index channels are weak and the results are sensitive to instrument noise/systematic bias

• NOAA/NASA are moving forward with an implementation of the V8 Total Ozone Retrieval Algorithm to be followed by the implementation of Kai Yang's Linear Fit SO2 algorithm developed for OMI

• Both algorithms running at STAR and an evaluation of the products is requested. A test day's processing can be supplied in NetCDF files (see Figs. next page)

• Plan to create the full month of January 2016 as part of our Algorithm Readiness Review and are working with the NDE BUFR team to switch the total ozone to this new product and add the SO2 estimates as well

• NOAA developing a volcanic ash product from VIIRS that will become operational in April-July time frame.
