The compiled data are available at
doi: 10.1594/PANGAEA.854832. The merged text table
described in this work, considered here as the main table, is
accompanied by four extra hies. One extra hie is a csv table
with detailed information about the number of observations
per variable, dataset, subdataset and pi. Two other extra
hies are text tables generated from the main table, and are
provided to help with the analysis of spectral data. These
two hies contain the spectral data aggregated within ±2
and ±6nm, respectively, of SeaWiFS, MODIS AQUA and
MERIS sensor bands. The hies are generated by assigning,
in each row of the main table, the closest spectral observation
within 2nm (or 6nm) of a sensor band. The centre
wavelength of each band and sensor used in the generation of
the hies is the following: SeaWiFS bands 1-8 were centred
at [412, 443, 490, 510, 555, 670, 765, 865] nm, respectively;
MODIS-AQUA bands 1-9 were centred at [412, 443, 488,
531, 547, 667, 678, 748, 869] nm, respectively; and MERIS
bands 1-13 were centred at [412, 442, 490, 510, 560, 620,
665, 681, 709, 753, 779, 865, 885] nm, respectively. An
exception to this procedure was made to conhrm that the
correct MOBY data are stored in the hies (see Sect. 2.2.1.
for discussion on how MOBY wavelengths are stored in the
main hie). Finally, a readme hie is provided to help the user.
