Quality Control

 

Raw Data

When this option is selected, raw data will be supplied in the data products: no action is taken to modify the data. In general, all scalar data is associated with a quality control flag. These flags are stored adjacent to the data values.

Oceans 2.0 API filterdpo_qualityControl=0

Clean Data 

Selecting this option will cause any data values with quality control failures (QAQC flags 3, 4 and 6) to be replaced with NaNs. “-clean” is added at the end of the filename.

Cast Delineation / Breaks:

Up casts only

Only data collected while the profiler is ascending the water column are selected. Individual up casts are identified and stored separately within one final data structure for file data products. A plot be produced for each day consisting of all up casts that began during that day. The break time is not strictly midnight, it is 0800 UTC (midnight PST, 0100 PDT).

Oceans 2.0 API filterdpo_cast=up_casts

Down casts only

Only data collected while the profiler is descending the water column are selected. Individual down casts are identified and stored separately within one final data structure. The time range specified will be broken up daily and a plot will be produced for each day consisting of all down casts that began during that day. The break time is not strictly midnight, it is 0800 UTC (midnight PST, 0100 PDT).

Oceans 2.0 API filterdpo_cast=down_casts

Stepped casts only

Only data collected while the profiler is stepped mode are selected (currently unique to VPS). Individual stepped casts (all up casts and stationary segments during a stepped cast) are identified and stored separately within one final data structure. Individual plots will be produced for each stepped cast.

Oceans 2.0 API filterdpo_cast=stepped_casts

All casts

Only data collected while the profiler is ascending, descending, or stationary in the water column are selected. Individual casts (up, down, stationary) are identified and stored separately within one final data structure. The time range specified will be broken up daily and a plot will be produced for each day consisting of casts (up, down, stationary) that began during that day. The break time is not strictly midnight, it is 0800 UTC (midnight PST, 0100 PDT).
