As part of the SPURS (Salinity Processes in the Upper Ocean Regional Study) project,
the Upper Ocean Processes Group at WHOI deployed a surface mooring at approximately 24.5N, 38 W, in
the salinity maximum region of the subtropical North Atlantic, on September 14, 2012 from the R.V. Knorr.
The buoy is equipped with two identical ASIMet systems,
each with an Argos transmittter. Hourly averages of ASIMet data are
transmitted continuously and delivered to the UOP lab every three hours for
Times in Iridium data files reflect the end of the hour during which
averaged data was collected.
A magnetic declination correction is applied to the winds. The value is -13.89284,
calculated using the IGRF
model on the NOAA NESDIS NGDC web site.
Note: The Argos transmitter on logger 37 stopped updating on October 6, 2012.
Data Access - Real time meteorology
This is unedited data, please use with caution.
Real time surface fluxes
Preliminary surface fluxes are calculated using the
bulk flux algorithm. Plots and data listings are available.
Note on metoerology text files
Text files begin with comment lines that begin with % to make them Matlab-compatible.
Header lines include the processing date, in local (Eastern) time.
There is also a column header line:
%year month day yday hr BPR ATMP SST WNDE WNDN HRH SWR LWR RN CND sal wnd_spd wnd_dir rain_rate
Times reflect the end of the hour during which averaged data was collected, in UTC.
