Near Real Time Service
The Near Real Time (NRT) Service
consists of daily Level-3 ocean color products matching
the FPS in information content. The NRT service is based on the merging
of MERIS and MODIS level-2 data over the whole globe.
Near real time products (NRT, at D+1) and consolidated near real time products (NRT, at D+3) are available as rolling archives 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, ...).
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).
