Description 580-586
Argo program is aimed at maintaining an
array of 3000 free drifting floats to measure temperature and salinity (T/S). Present
study consists a PC-based system developed for visualization and quality
control of T/S profiles obtained from Argo floats. The system, coded in Java,
is user interactive and runs on Windows platform. Default the Argo T/S profiles
pass through 19 automatic checks and quality flags are assigned. Using the
system, T/S profiles that failed the automatic Argo tests undergo visual
review. This visual review is done to determine whether automatic Argo tests
were excessively flagging good measurements as bad or vice-versa, to motivate
modifications to automatic Argo tests and to determine whether additional tests
were necessary to catch problems that could not be detected by the existing
tests. Visual review is done by comparing with 1° X 1° monthly climatologies
from WOA01. Profile records deviating beyond 2 standard deviations from the
mean are flagged as bad. Provision is also given to compare individual T/S
profiles with previous 5 profiles via a waterfall plot.
