Level 1 data (shear probes)

TO DO: Fit the parameter names and definitions to the NetCDF parameter attributes

Level 1 data refers to the full resolution data in physical units, e.g. the regularly sampled time series of converted shear probe data. If needed, a transfer function for shear is given. Below, a table with parameters included in the level 1 data set is compiled.

Numbers in the last column indicate:

required=1 are the absolute minimum parameter required for a data set
required=2 are preferred/recommended parameter
required=3 are optional parameter
Parameter Name CF parameter Standard Name Units of measurement dimension required
PRES 1
0		 sea_water_pressure
water_pressure		 dbar TIME 1,2
TIME 1 time days since 1950-01-01 00:00:00 UTC TIME 1
SHEAR 0 water_velocity_shear s-1 [TIME, n_shear_sensors] 1
VIB 0 platform_vibration NA [TIME, n_vibration_sensors] 2
ACC 0 platform_acceleration m s-2 [TIME, n_acc_sensors] 2
TEMP 1
(0)		 sea_water_temperature
(water_temperature)		 degree_Celsius [TIME,n_T_sensors] 2
CNCD 1
(0)		 sea_water_electrical_conductivity
(water_electrical_conductivity)		 S m-1 [TIME_FAST,n_C_sensors] 2
GRADT temperature_gradient [TIME, n_gradT_sensors] 3
GRADC conductivity_gradient [TIME, n_gradC_sensors] 3
PITCH 1 platform_pitch_angle degree [TIME] 2
ROLL 1 platform_roll_angle degree [TIME] 2
