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

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

22. 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

23. 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

24. 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.
