GEOMS-TE-Radiance-GA (Radiance Global Attributes Template)
| # | Variable name | Variable value | Comment |
| 0 | DATA_DESCRIPTION | Spectral radiance measurements made with a spectroradiometer on-board a ship | Free description of the data set |
| 1 | DATA_DISCIPLINE | ATMOSPHERIC.PHYSICS;INSITU;SHIP | Discipline field; Acquisition method; Acquisition platform |
| 2 | DATA_GROUP | EXPERIMENTAL; PROFILE.MOVING | Origin of the data (experimental, model, or a combination of both);spatial characteristics of the data. |
| 3 | DATA_LOCATION | POLARSTERN | The name of the ship (platform) |
| 4 | DATA_SOURCE | SPECTRORADIOMETER_ULEICESTER001 | The 1st field indicates the type of instrument that provides the data in the file; the 2nd field indicates the institutional owner of the instrument (acronym) and a unique numerical identifier to distinguish between instruments from the same owner: in the example given the instrument belongs to the University of Leicester (ULEICESTER) |
| 5 | DATA_LEVEL | H2 | Example: level 2 data at a hourly temporal sampling |
| 6 | DATA_VARIABLES | DATETIME;
LATITUDE;
LONGITUDE;
WAVELENGTH;
RADIANCE.DOWNWELLING_SPECTRAL;
RADIANCE.UPWELLING_SPECTRAL
| For the moving ship, latitude and longitude will be datetime-dependent arrays;the radiance variables will be arrays depending on wavelength |
