Accessing data in the cruise directory
- ADCP data in raw can be accessed using Matlab and the UH
program read.m These data, with no other information, will
have values of velocity, amplitude, and correlation
(or spectral width) for each beam. The time is the instrument time, which
was set to the computer time when logging was started.
- ADCP data in raw and gbin can be combined using Matlab and the
UH program get_xfraw.m. This will result in a file that includes
earth coordinates, heading, position, and an estimate of ocean
velocity over the time range of the raw data file.
- The proc directory contains the processing tree for each instrument.
One codas database (and supporting files) exists for each instrument+pingtype
combination. In each processing directory (eg vg0810/proc/os75nb)
these may be of interest:
||files to use
|coarse resolution averaged ocean velocity
|moderate resolution averaged ocean velocity
|every bin and every profile (matlab)
|every bin and every profile (netCDF)
|every bin and every profile (CODAS database)
|figures from the cruise
