- repres_orbital_vel - Code to compare ADV and workhorse based representative orbital velocity amplitude
- recreate_time_series - Recreating time series from measured data (similar to Abreu et al.)
- vandera_bedload - generated matfile that contains the vandera based bedload calculation (both from direct waveform and then from workhorse).
- skewness - skewness is computed betweeen ADV calculations and empirical relationships.
- compare_bedload - bedload calculations in vandera and measured values (MPM).
- find_bedload_compare.m - code that compares the bedload from vandera and measured values - it does require matfiles that are first generated by the find_skewness_adv.m.
- Steve_ana_waveforms- Steve generate the wave forms from analytical calculations
- waveform_compare - compare the wave form characteristics empirical vs data from ADV(used Steve's mat file).
- Compare asymmetry deduced from bulk wave statistics via Ursell number with asymmetry measure with near-bottom instruments
- But first, demonstrate/test routines for reading/processing instrument data
- Measures of asymmetry vary. Some are best calculated for a singe wave, others are amenable to field measurements.
- TODO: summarize asymmetry formulae and code
- The stats file has some missing depths...we skip these in processing, but have not investigated the underlying bursts. Some of the bursts where depth is missing are also missing some pressure measurements. These break the calcs.
- TODO: Add some basic QA/QC to the bursts to replace missing or bad data where possible, and to skip bursts that don't meet QA standards.
- TODO: Complete analysis of rotation into wave-propagation direction. I think
wdsreturns the correct direction, andpuvqreturns a direction that is 180 deg. out...the direction waves are coming from. - TODO: Complete calcs. of comparable statistics. Best version of du/dt for acceleration statistics? Hilbert transform (per Malarky and Davies, 2012) for acceleration asymmetry?
