Full Product Set (FPS)

The Full Product Set (FPS), also called GLOB_4KM, covers the merged Level-3 ocean color products in the time period 1997-today.

The FPS data set consists of ocean color merged data products using the merging algorithms recommended at the first GlobColour workshop in Villefranche sur mer (France) on the 4-6 December 2006. The FPS includes level 3 merged products as daily, 8-days and monthly averaged products mapped on a common ISIN 4.63km grid.

FPS archive products (RAN, at D+30) are available on a dedicated ftp server or though the HERMES data portal (see below). Global products at 4.6 km resolution are available (GLOB_4KM) as well as several specific large regions of interest at different spatial resolutions (EURO_4KM, EURO_2KM, ...)

A full scale validation has been performed and all results have been presented at the second user workshop, in Oslo, on November 20-22 2007.

Distributed merged products are:

  • Chlorophyll-a, case I water (CHL1),
  • Chlorophyll-a, case II water (CHL2),
  • Total Suspended Matter (TSM),
  • Coloured dissolved and detrital organic materials (CDM),
  • Particulate back-scattering coefficient (bbp),
  • Diffuse attenuation coefficient (KD490),
  • Fully normalised water leaving radiances at 412, 443, 490, 510, 531, 550-565, 620, 665-670, 681 and 709 nm (Lxxx),
  • Relative excess of radiance at 555 nm (EL555),
  • Aerosol optical thickness over water (T865),
  • Cloud Fraction (CF).

The FPS files are also accessible via a dedicated FTP service.
Use server ftp.acri.fr , login globcolour_data , password fgh678 for log-in.
Goto directory GLOB_4KM, EURO_4KM, EURO_2KM then RAN


The ftp directory structure of the RAN archive is described below:

/covered area and resolution (GLOB_4KM, EURO_4KM, EURO_2KM, ...)

/RAN for archive or DT to access a rolling archive

/parameter name (CHL1, L412, EL555, CF...)

/MERGED

/merging mode (WEIGHTED | GMS | SIMPLE)

/year (1997...)

/binning period (DAILY, 8DAYS, MONTHLY)

/products (L3b..., L3m...)

Note: the merging mode also contain the list of input data sensors (separated by an hyphen).
Instruments accronyms are used: MER for MERIS, MOD for MODIS and SWF for SeaWiFS.
Any combinaisons of these names is allowed (e.g. MER, MOD or SWF alone, MERMOD for merged MERIS and MODIS data, MERMODSWF for the merging of the three instruments data).

The ftp directory structure of the DT products is described below:

/covered area and resolution (GLOB_4KM, EURO_2KM)

/DT

/year_month_day

/products (L3b..., L3m...)

Note: the NRT archive is a 30-days rolling archive.
