Netcdf dimensions (shear probes)
Netcdf dimensions (shear probes)
| Dimension Name | Description |
|---|---|
| TIME | The length of the record from turbulence (fast) data channels |
| TIME_*** [math]\displaystyle{ ^a }[/math] | length of the record from slow data channels (if different than fast) |
| TIME_SPECTRA | 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_SHEAR_SENSORS | number of shear channel (shear sensors) |
| N_***_SENSORS [math]\displaystyle{ ^b }[/math] | number of *** channel (sensors) |
| N_SH_ACC_SPEC [math]\displaystyle{ ^c }[/math] | number of shear-acceleration cross spectra |
| N_SH_VIB_SPEC [math]\displaystyle{ ^d }[/math] | number of shear-vibration cross spectra |
| N_GLOBAL_VALUES [math]\displaystyle{ ^e }[/math] | dimension for 1 data point (for the entire analysis) |
[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.
[math]\displaystyle{ ^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]\displaystyle{ ^c }[/math] number of shear sensors x number of ACC sensors
[math]\displaystyle{ ^d }[/math] number of shear sensors x number of VIB sensors
[math]\displaystyle{ ^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.
