Sentinel-3 Atmosphere Products – AOD and FRP

• Implementation of S-3 AOD and FRP products

• Triggered in response to request from the EC User Forum in 2015

• Change approved by the EC in early 2016

• The approach is for EUMETSAT to undertake the processing and the

dissemination of the NRT Aerosol Optical Depth (AOD) & Fire Radiative Power

(FRP) products, whereas ESA will undertake the processing and the

dissemination of the NTC AOD & FRP products

• Implementation schedule under responsibility of ESA

• Deployment on the operational ground segment in Q4 2017/Q1 2018

• AOD & FRP NRT products will be disseminated over EUMETCast


Description AOD - Aerosol Optical Depth FRP - Fire Radiative Power

Resolution Aggregated “super pixel” ~4.5 km x 4.5 km SLSTR native resolution (~500m/1km)

Coverage Global Global

Product Level 2 2

Timeliness NRT (ESA is responsible for the corresponding NTC products)

Availability Q4 2017/Q1 2018 Q4 2017/Q1 2018

Application Areas

• global aerosol monitoring and forecasting • regional air quality monitoring and forecasting • sand and dust storm warning and assessment • volcanic ash monitoring • climate change services and climate research

• global emissions monitoring from biomass burning relevant to air quality and climate applications

Motivation Currently CAMS relies on MODIS aerosol data. This will not be available in the future and the development of S3 global aerosol products is essential.

CAMS uses FRP data from geostationary imaging missions and from polar orbit relies on MODIS data. MODIS FRP data will not be available in the future and the development of S3 FRP products is essential.

• SLSTR level-1 channel co-registration and re-gridding • Uncertainty characterization at all levels for SLSTR and OLCI • Focus on algorithms improvements

• Product performance assessments

• Long-term Cal/Val, focused calibration studies/monitoring

• Investment in Fiducial Reference Measurements

EPS-SG UVNS Sentinel-5 UV-NIR-SWIR Hyper Spectral Instrument from Low-Earth Polar Orbit

• Sentinel-5 will build on the heritage from the

GOME/SCIAMACHY/GOME-2/OMI series of

instruments and will provide continuity with

these instruments

• 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

• Products: O3, NO2, SO2, HCHO, CH4,

CO, CHOCHO, UV, AAI, AOD, ALH,

CLD, HSC, SUR


• Sentinel-4 has heritage from the

GOME/SCIAMACHY/GOME-2/OMI

series of instruments

• Primary focus is the monitoring of air

quality in the European domain with

high spatial and temporal resolution

• The spatial resolution will be ~ 8 x 8 km with hourly

temporal resolution

• Sentinel-4 level 1 and 2

products will be produced

operationally by EUMETSAT

• Products: O3, NO2, SO2, HCHO, (CHOCHO), UV,

Additional Atmosphere Data Services NOAA OMPS Data Requests

• EUMETCast users receive OMPS Nadir Profile EDRs (in BUFR)

• Since 12 May 2016 EUMETCast users also receive OMPS Total Column EDRs (in BUFR)

• This product consists of total column ozone, surface pressure and corresponding quality indicators

derived from the OMPS (Ozone Mapping and Profiler Suite) instrument on board Suomi-NPP.

• The product is distributed on EUMETCast Europe:

• Filename convention:

W_XX-EUMETSAT-

Darmstadt,SOUNDING+SATELLITE,NPP+OMPS_C_EUMP_YYYYMMDDHHmmss_v<version>r<re

vision>_TC_EDR.bin

• Example filename:

W_XX-EUMETSAT-

Darmstadt,SOUNDING+SATELLITE,NPP+OMPS_C_EUMP_20140312044918_v1r0_TC_EDR.bin

• Note: on Saturdays, OMPS data are not available from NOAA because the instrument is

commanded into a special mode.


Additional Atmosphere Data Services JAXA GOSAT Request

• Initial problems with timeliness of GOSAT L1b data were reported

by CAMS

• EUMETSAT looked at getting the data from JAXA and passing

them on to CAMS to save time

• Sample data provided for GOSAT L1B, v161 and of v200 in May

2016

• In July CAMS reported that JAXA had agreed to also make

available a true near-real-time product which would be

disseminated via ESA

• EUMETSAT activities paused pending fresh input


Additional Atmosphere Data Services JPSS-1/S-NPP Distribution

• S-NPP data are already made available to CAMS

• JPSS-1 is due for launch in early 2017 and will carry a similar

instrument suite

• Both S-NPP and JPSS-1 will be operated in parallel

• CAMS is asked to identify whether or not there is an interest in

receiving global data in parallel from S-NPP and JPSS-1 during the

period of parallel operations


Additional Atmosphere Data Services S5-P Distribution

• EC released a change request to ESA & EUMETSAT to analyse

the possible dissemination of S-5P NRT L1 & L2 Products over

EUMETCast. Pre-analysis provided positive results. Discussions

with ESA on-going on data repatriation. Targeting operational

delivery service early 2018.
