sea_surface_wave_spectral_principal_direction_primary_sensor_secondary_telemetry degrees [UAAA]
The wave direction in each frequency band, calculated from the second-order components of the wave directional spectrum. Since there is an ambiguity of 180 degrees in the calculation of Alpha2 (i.e. 90 degrees and 270 degrees result in equivalent spectra), the value closer to Alpha1 is selected. Primary sensor refers to the data measured by the primary sensor when more than one sensor is installed on the station. Secondary telemetry refers to the secondary transmitter on board the station when more than one transmitter is installed.
