List of measurement wind profiles id field name definition 0 mie_reference_pulse_quality_flag binary uint8 size: 1 Mie internal reference quality flag. This field is a 8-bit long, bit-packed field, of reference pulse validity information. When the data is valid, this field will be 0. Bit 1: Overall validity. Data invalid 1, otherwise 0; Bit 2: For Mie, peak not found 1, otherwise 0. For Rayleigh, this is always 0; Bit 3: All reference pulses corresponding to the current measurement eliminated (source packet invalid, data corruption, or laser frequency unlocked) 1, otherwise 0; Bit 4: Default 0; Bit 5: Default 0; Bit 6: Default 0; Bit 7: Default 0; Bit 8: Default 0 1 rayleigh_reference_pulse_quality_flag binary uint8 size: 1 Rayleigh internal reference quality flag. This field is a 8-bit long, bit-packed field, of reference pulse validity information. When the data is valid, this field will be 0. Bit 1: Overall validity.
