  Name: Merged MERIS/MODIS/SeaWiFS/VIIRS global level-3 ocean colour products at 1.0 and 4 km (CHL1, Rxxx, ...)
  Abbreviation: HERMES
  Description: HERMES is a web portal providing access to a data set that consists of daily, weekly and monthly Level-3 ocean colour products (NRT and off-line), among others: CHL1, CHL2, BBP, CDM, Rxxx, KD490, T865, transparency, cloud fraction). Aknowledgment: "GlobColour has been originally funded by ESA with data from ESA, NASA, NOAA and GeoEye. This reprocessing version has received funding from the European Communitys Seventh Framework programme ([FP7/2007-2013]) under grant agreement n 282723 [OSS2015 project]." The data set (September 1997 - present) is computed by the merging of MERIS, SeaWiFS, MODIS and VIIRS level-2 data over the whole globe as per availability. The best resolution of the archive products is 4.6km. Extraction over user defined areas is available. A subscription mode provides 1 km resolution NRT data (at J+1) on any user-defined area of interest.
