Moored air-sea flux measurements in support of satellite ocean wind research
UNH has been working closely with J. Edson at the Univ. of Connecticut in a team effort to collect a series of long-term ocean field datasets of air-sea momentum and heat flux using several different buoys and platforms. One specific goal of this collaboration is to use these in situ measurements of wind stress to support improved interpretation of ocean satellite measurements, specifically ocean surface wind vector as collected by recent QuikSCAT, ASCAT, OSCAT and RapidSCAT sensors.
UNH/UCONN Air-Sea Flux Buoy Data Information and Access

The links below provides THREDDS access to our available field buoy air-sea flux datasets. Metadata within the netCDF files should contain the documentation to inform data usage policy and to support initial investigations. We appreciate any feedback as well as opportunities to collaborate in the application of these data. If you encounter any trouble or have questions, please send an email to doug.vandemark@unh.edu

These data represent averages of 20 min. flux and scalar estimates, usually collected hourly from 0 to 20 minutes past the hour. For the UNH (JLMO) datafiles all segments are provided without filtering. Filtering to leave only the most reliable data, avoiding rain or other effects, involves setting thresholds on variables including relative humidity and standard deviations in the temperature and vertical velocity data. Details and example matlab code are provided in the following QA/QC document:

  • Quality control filtering procedures for buoy air-sea flux datasets

  • Any data fields requiring use of bulk flux algorithms were computed using COARE 3.5 as detailed in Edson et al. 2013, DOI: 10.1175/JPO-D-12-0173.1.
