Abstract:
Abstract. A global compilation of in situ data is useful to evaluate the
quality of ocean-colour satellite data records. Here we describe the data
compiled for the validation of the ocean-colour products from the ESA Ocean
Colour Climate Change Initiative (OC-CCI). The data were acquired from
several sources (including, inter alia, MOBY, BOUSSOLE, AERONET-OC, SeaBASS, NOMAD,
MERMAID, AMT, ICES, HOT and GeP&CO) and span the period from 1997 to 2018.
Observations of the following variables were compiled: spectral
remote-sensing reflectances, concentrations of chlorophyll a, spectral
inherent optical properties, spectral diffuse attenuation coefficients and
total suspended matter. The data were from multi-project archives acquired
via open internet services or from individual projects, acquired directly
from data providers. Methodologies were implemented for homogenization,
quality control and merging of all data. No changes were made to the
original data, other than averaging of observations that were close in time
and space, elimination of some points after quality control and conversion
to a standard format. The final result is a merged table designed for
validation of satellite-derived ocean-colour products and available in text
format. Metadata of each in situ measurement (original source, cruise or
experiment, principal investigator) was propagated throughout the work and
made available in the final table. By making the metadata available,
provenance is better documented, and it is also possible to analyse each set
of data separately. This paper also describes the changes that were made to
the compilation in relation to the previous version (Valente et al., 2016).
The compiled data are available at
