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
