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. The parameter names and definitions fit the NetCDF parameter attributes.
In the standard names, "sea_water" can be replaced with "water" if working in freshwater environments. This is specified in some entries below but not all.

TIME
The length of the record from turbulence (fast) data channels
TIME_*** [math]\displaystyle{ ^a }[/math]
The length of the record from the *** sensor (e.g., CTD or SLOW)
N_SHEAR_SENSORS
number of shear channel
N_***_SENSORS
number of *** channel (e.g., N_VIB_SENSORS, N_ACC_SENSORS)
[math]\displaystyle{ ^a }[/math] Typically we assume TIME for the fast-sampled microstructure channels, and eventually _SLOW or _CTD for slower sampled channels such as CTD and tilt sensors. If the application requires different time stamps for different sensors, this can be utilized like TIME_PITCH, TIME_ACC etc.
