3.1.5.8. Python direct read access to CODAS dataΒΆ

get_profiles: getting all bins and all profiles from a CODAS database

  • extract averaged data, every bin and every profile, including access to many variables (time, position, velocity, amplitude, temperature, heading)

  • example: using dbname as the name of the database (i.e. the CODAS database file collection exists as adcpdb/dbname*.blk

from pycurrents.codas import get_profiles
data=get_profiles(dbname)

Typical variables of immediate interest are:



variable

u, v

Ocean zonal and meridional velocity component profiles.

uship, vship

Zonal and meridional velocity components of the ship.

heading

Mean ship heading during the ensemble.

depth

Bin centers in nominal meters (no sound speed profile correction).

tr_temp
