Table 1 Files of the GLORIA dataset and their content.

GLORIA_variables_and_methods.xlsx

Excel file with several sheets:

Data headers: Key to columns and units in the ancillary and metadata table (GLORIA_meta_and_lab.csv).

Radiometry methods: Details of the instruments and their setups for the radiometric measurements.

Chla methods, TSS methods, aCDOM Methods: Method details for the respective water quality measurements. Cross-referencing to data entries requires the dataset ID and methodology name from the table GLORIA_meta_and_lab.csv.

References: List of references cited in this file.

GLORIA_meta_and_lab.csv

Ancillary information, metadata and water quality measurements associated with each R_rs spectrum. The data fields in this file are defined in GLORIA_variables_and_methods.xlsx sheet ‘Data headers’.

GLORIA_Rrs.csv

Remote sensing reflectance (R_rs, sr⁻¹) spectra (Rrs_350, Rrs_351, …, Rrs_900). The first column is the GLORIA sample ID.

GLORIA_Es.csv

Above-water downwelling irradiance (E_s, W m⁻² nm⁻¹) spectra (Es_350, Es_351, …, Es_900). The first column is the GLORIA sample ID.

GLORIA_Lw.csv

Water-leaving radiance just above the water surface (L_w, W m⁻² sr⁻¹ nm⁻¹) spectra (Lw_350, Lw_351, …, Lw_900). The first column is the GLORIA sample ID.

GLORIA_Lt.csv

Above-water upwelling radiance (L_t, W m⁻² sr⁻¹ nm⁻¹) spectra (Lt_350, Lt_351, …, Lt_900). The first column is the GLORIA sample ID.

GLORIA_Lu.csv

Upwelling radiance just below the water surface (L_u, W m⁻² sr⁻¹ nm⁻¹) spectra. The first column is the GLORIA sample ID.

GLORIA_Lsky.csv

Sky radiance (L_sky, W m⁻² sr⁻¹ nm⁻¹) spectra (Lsky_350, Lsky_351, …, Lsky _900). The first column is the GLORIA sample ID.

GLORIA_qc_flags.csv

Quality control (QC) flags for each QC procedure described in Table 2. A value of 1 indicates that the issue has been detected.

GLORIA_qc_ancillary

Ancillary information for quality control flags listed in Table 3.

GLORIA_Rrs_mean

Mean of R_rs measurements and the number of replicates of entries where the standard deviation is available.

GLORIA_Rrs_std

Standard deviation of R_rs measurements. The number of replicates for the calculation of the standard deviation is provided in GLORIA_Rrs_mean. Standard deviation is only available for a subset of the dataset.

GLORIA_waterqual_uncert

Mean, standard deviation and number of replicates for water quality measurements. The replicate type is specified as ‘field’ (separate water samples taken in the field) or ‘lab’ (replicate analyses of the same water sample). This information is available for a subset of the dataset.
