ENVISAT binary datetime id field name definition 0 days binary int32 size: 4 days since January 1st, 2000 (may be negative) unit: "days since 2000-01-01" 1 seconds binary uint32 size: 4 seconds since start of day unit: "s" 2 microseconds binary uint32 size: 4 microseconds since start of second unit: "1e-6 s"

binary uint8	size: 1
Positive integer number for the current L1 measurement between 0 and M_channel (M_Mie or M_Rayleigh for the Mie and Rayleigh datasets respectively) pointing to the L2B profile. Zero indicates the L1 measurement was not used ; a number between 1 and M_channel points to an L2B profile

binary uint16	size: 2
Relative weight (integer number between 0 and 1000) of the current L1 measurement making up the observation indicated by L1_Measurement_Used

This parameter shall be used to correct the reported HLOS wind from pressure modifications brought by the assimilation unit: "1e-6 m/s/Pa" converted unit: "m/s/Pa" (multiply by 1/1000000) 3 rayleigh_wind_to_temperature binary int16 size: 2 First-order derivative of the HLOS wind with respect to the temperature inside the sensing volume. This parameter shall be used to correct the reported HLOS wind from temperature modifications brought by the assimilation unit: "cm/s/K" 4 rayleigh_wind_to_backscatter_ratio binary int16 size: 2 First-order derivative of the HLOS wind with respect to the backscattering ratio inside the sensing volume. This parameter shall be used to correct the reported HLOS wind if the reference backscatter ratio is modified unit: "cm/s" 5 reference_pressure binary uint32 size: 4 Reference pressure used for inverting the Rayleigh response into an HLOS wind. This pressure information is taken from the numerical weather prediction model unit: "Pa" 6 reference_temperature binary uint16 (double) size: 2 Reference temperature used for inverting the Rayleigh response into an HLOS wind. This temperature information is taken from the numerical weather prediction model unit: "1e-2 K" converted unit: "K" (multiply by 1/100) 7 reference_backscatter_ratio binary uint32 (double) size: 4 Reference backscatter ratio used for inverting the Rayleigh response measured by the lidar. This parameter is provided by the L1B algorithm unit: "1e-6" converted unit: "" (multiply by 1/1000000) 8 rayleigh_error_quantifer binary uint16 size: 2 Error quantifier in cm/s associated to the Rayleigh height bin wind velocity unit: "cm/s" 9 integration_length binary uint32 size: 4 Integration length for the reported Rayleigh height bin wind unit: "m"
