The JKEO3 sampling is almost
same with JKEO2 and based on the m-TRITON of which prototype is TRITON
moorings in the tropical Pacific.
All
data collected from the JKEO3 mooring are publicly available. Hourly surface
and subsurface data from the JKEO3 mooring are transmitted in near real-time.
In addition, spot values of Argos position data are transmitted
opportunistically Daily averaged surface and subsurface data from the JKEO3
mooring and higher resolution data recorded onboard the mooring will be made
available in the data page in this web site.
The
table below describes the sampling schemes for the JKEO3 moorings.
Observation times in data files are assigned to the center of the averaging
interval unless otherwise noted. For example, daily averages are computed
starting at 0000 UTC and are assigned an observation "time stamp"
of 1200 UTC.
JKEO3
measures winds, sea surface air temperature and relative humidity, sea
surface temperature and salinity (SST and SSS), subsurface temperatures and
salinity, and short wave and long wave radiation.
