Dataset: Met/Flux data - Revision 2 from NOAA Ship Ronald H. Brown cruise RB-08-02 in the Southwest Atlantic sector of the Southern Ocean near South Georgia Island in 2008 (SO_GasEx project)

SO-GasEx Met/Flux data - Revision 2   (See MetFlux Revision 1, v.18 February 2009 for earlier data)

 

The values represent 10 minute means and include interpolated data to fill in data gaps.
There is a period at the end of the cruise with no radiative flux data.
The missing data are flagged with -999.

In all cases, the fluxes use the convention that positive implies upwards.
The fluxes and wind speeds are computed relative to fixed earth,
i.e., they have not been corrected for currents.

 

Updates in Revision 2:
  - Additional decimal point included for wind speeds and temperatures.

 

 - Radiative flux data and improved SST data for transit back to Uruguay now included.

 

 - CO2 fluxes are now included using the COAREG algorithm.  The algorithm has been tuned to 

   best match the direct covariances fluxes measured duirng GasEx 98 and SO Gasex.

 

 - Also included are the delta CO2 measurement provided by NOAA/AOML and the Schmidt number
   and solubility provided by the COAREG algorithm.   The Schmidt number is used to compute 
   K660 = wCO2/delCO2*sqrt(ScCO2/660)
 
- The solubility is included for those who want to convert delCO2 units to uatm.
 

 Additional Parameters in Revision 2:

 - wCO2 (umol/m2/s):               CO2 flux computed from COAREG (umol=micromole)  
 - delCO2 (mmol/m3):              delta CO2 with corrections applied for solubility  
 - K660 (cm/hr):                       Transfer velocity for CO2 from COAREG adjusted to Sc=660   
 - Solubility (mole/m^3/atm):     Solubility of CO2 at sea surface  
 - ScCO2:                                Schmidt number of CO2 under ambient conditions
