ctdproc.proc.cleanup_ud

ctdproc.proc.cleanup_ud(ds)

Clean a single down- or up-cast and calculate derived variables.

Despikes t1/t2, glitch-corrects c1/c2/t1/t2, computes salinity (practical and absolute) via ctdproc.calcs.calc_sal(), despikes/glitch-corrects the salinity fields, and finally calls ctdproc.calcs.calc_temp() and ctdproc.calcs.calc_sigma() to add conservative/potential temperature and potential density anomaly.

Parameters:

ds (xarray.Dataset) – CTD time series for a single cast (down or up). Required attrs: spike_thresh_t, spike_thresh_s, diff_t/prod_t, diff_c/prod_c, diff_s/prod_s, bounds_s.

Returns:

ds – Cleaned cast with derived salinity, temperature and density fields.

Return type:

xarray.Dataset
