ECOOP – WP2.3

Ensure proper and maximum real time delivery of remote sensing data

Participants: CNR, ENEA, DMI, IFREMER, AZTI-Tecnalia, NERC, CLS, PdE, NUIC, DNSC


Objectives

  • integrate existing satellite observing systems

  • coordinate access to Earth Observation (EO) products taking full advantage of existing national and European resources

  • ensure advanced satellite products for monitoring and assimilation into ECOOP models during TOP

    Links with other WPs

  • WP3: satellite products based upon the results of the R&D activity

  • WP8: ECOOP information management


First year activities
First year activities

Design of the RT and NRT data satellite acquisition and delivery

system for the TOP phase

 D2.3.1.1 (CNR, Ifremer, CLS, DMI)

Activities:

  • analysis of current satellite systems/products

  • analysis of WP3 outcomes and planned activities for the next 6 months

  • analysis of the in situ data required to produce advanced R/S products

  • design of the RS observing system for TOP: data input, products, format, delivery systems


Satellite products
Satellite products

The new Satellite products to be assimilated by ECOOP models

include:

  • SST merged R/S - in situ products (Gulf of Biscay, Adriatic and Baltic Seas)

  • Altimetry merged R/S with tide gauges and mean dynamic topography (Gulf of Biscay and Black Sea)

  • Ocean Colour merged R/S - in situ products (Gulf of Biscay and Adriatic Sea)

ECOOP-WP3

  • During TOP, specific ECOOP SST data will be produced by EuroGOOS sub-region SST processing systems after introducing the improvements resulting from WP3

  • SST data input:

IFREMER

Present:

IBIROOS area is covered by the multi-sensor L4 SST products computed by Ifremer using data from both infra-red and micro-wave radiometers

Daily global SST with a resolution of 0.1°res.

NRT SST are produced since October 2007.

ECOOP Improvements

The ODYSSEA chain will be used and tuned to provide daily SST fields at a higher resolution (0.02° res.) over the IBIROOS area.

Improvements in the intercalibration using in situ data

Including all coastal stations

Data format : Netcfd, complying to CF-1.0 convention and GHRSST format

Delivery system

ftp and OpenDAP


SST: Baltic Sea together with a measure of uncertainty for each observation

DMI

  • Present:

  • L2P data corrected from skin to subskin

  • single sensor error bias applied to all sensors

  • relevant satellite observations used as input for the Baltic Sea L4 processing system (DMI) at 0.03° res.

ECOOP Imprevements

Merged multi-sensor L4 at 0.03° res.

Adjustment of all satellite observations to the most accurate sensor (AATSR)

Include near-real time MARNET buoy observations in the L4 analysis, if required.

Data format : Netcfd, complying to CF-1.0

convention and GHRSST format

Delivery system

ftp and OpenDAP


SST: Adriatic together with a measure of uncertainty for each observation

CNR

Present:

Adriatic Sea is covered by the several SST products provided by the CNR

Daily images at 1km res. from AVHRR and MODIS

Daily SST data over the Adriatic model grid (AREG), 5km

NRT Mediterranean multi-sensor OISST (L4) at 1/16° res.

NRT SST Adriatic products available since October 2002, Mediterranean multi-sensor L4 since 2006.

ECOOP Improvements

Merged multi-sensor L3 over AREG grid

(with adjustment of all satellite observations to the most accurate sensors (AATSR/MODIS terra (4μm))

Data format : Netcfd, complying to CF-1.0 convention and GHRSST format

Delivery system

ftp and OpenDAP/THREDDS

Black Sea : A new regional product together with a measure of uncertainty for each observation

  • SLA relative to new mean profiles

    • Using new standard corrections  more consistent with SSH

    • Performed on longer periods (except for T/P : 7-years reference period)

  • Using a dedicated regional processing

    • Data selection with specific criteria based on mean profiles quality

    • Higher resolution

    • Local LWE correction (HF aliasing, orbit and tidal residual error)

Period 1992-2005 computed for all missions –> MHI + other deliveries

Standard AVISO 1/3°


New Real Time product together with a measure of uncertainty for each observation

2 days gain

Old acquisition status based on IGDR and OGDR products

  • - OGDR do not have accurate orbit estimation

  • Merging of recent information (eddies, fronts) contained in the OGDR with large scale information from IGDR

  •  Useful for short term forecasts

Product delivery:

The product delivery occurs after the ongoing validation phase and is based on existing Ifremer's

facilities:

ftp anonymous access:

ftp://ftp.ifremer.fr/ifremer/cersat/products/gridded/ocean-color/

web services:

NAUSICAA web server http://www.ifremer.fr/nausicaa/marcoast/index.html

PREVIMER web server http://www.previmer.org

Opendap access is actually being setup and will be available for the IBI-ROOS area and all the

ocean color products

Present

ECOOP Improvements

Chlorophyll estimated with different algorithms for case 1 and case 2 waters

A new processing chain will be developed for MERIS

.

Ad hoc OC products will be developed for modelling data validation and assimilation based on

modelling requirements. In particular daily, weekly and monthly chlorophyll and K490 products will

be developed using all the available satellite over the new Adriatic model grid (2km). This data will

substitute the ADRICOSM AREG products currently produced.

Delivery system & data Format

This delivery system will be upgraded in framework of the ADRICOSM-STAR project. In particular,

historical data, RT and NRT data will be delivered as netcfd CF-1.0. The data will be also available

from CNR-ISAC-GOS OpenDap facility. Accessible via THREEDS at:

http://fe4.sic.rm.cnr.it:8080/thredds/config/adricosm_star.html

Satellite data format harmonization together with a measure of uncertainty for each observation

  • All data already written in standard, internationally agreed format

  • (netCDF, CF-1.0)

  • SSTGHRSST format

  • Altimetry AVISO format

  • Ocean colour  MERSEA format

  • Data delivery based on existing ftp and opendap servers.
