Netcdf dimensions (shear probes)
Netcdf dimensions (shear probes)
| Dimension | Level | Description |
|---|---|---|
| TIME | L1 | length of the record from turbulence (fast) data channels |
| TIME_*** <math>^a</math> | L1 | length of the record from slow data channels (if different from fast) |
| N_SHEAR_SENSORS | L1 | number of shear channels (shear sensors) |
| N_***_SENSORS <math>^b</math> | L1 | number of *** channel (sensors) |
| TIME | L2 | length of the record from turbulence (fast) data channels |
| N_SHEAR_SENSORS | L2 | number of shear channels (shear sensors) |
| TIME_SPECTRA | L3 | length of the record of average times of spectral segments. This also equals time of dissipation estimates. |
| N_WAVENUMBER | length of the wavenumber array | |
| N_SH_ACC_SPEC <math>^c</math> | number of shear-acceleration cross spectra | |
| N_SH_VIB_SPEC <math>^d</math> | number of shear-vibration cross spectra | |
| N_GLOBAL_VALUES <math>^e</math> | dimension for 1 data point (for the entire analysis) |
<math>^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.
<math>^b</math> Please use these examples for related sensors:
N_VIB_SENSORS for vibration (piezo-acceleration) sensors
N_ACC_SENSORS for vibration acceleration sensors
N_GRADT_SENSORS for thermistors
N_GRADC_SENSORS for microconductivity sensors
<math>^c</math> number of shear sensors x number of ACC sensors
<math>^d</math> number of shear sensors x number of VIB sensors
<math>^e</math> This dimension is 1x1. Use, for example, for N_FFT_SEGMENTS (number_of_fft_segments), SPEC_STD (standard_deviation_uncertainty_of_shear_spectrum), and is one value for the entire analysis.
