sea_surface_wave_spectral_principal_direction_primary_sensor_primary_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. Primary telemetry refers to the primary transmitter on board the station when more than one transmitter is installed.
