The enhanced DCFS worked almost flawlessly during its deployment. The telemetered fluxes and means were used to create the results given here before recovery, which is an obvious advantage of real-time delivery of research-quality data. The realtime DCFS has now been deployed on a number of research buoys including our TPOS mooring, the X-Spar, OOI surface moorings and the recently concluded INCOIS deployment in the Bay of Bengal. As a result, the DCFS is reliable and ready for deployment on the Tier-2 moorings.
The enhanced mooring developed for this project can be considered a proto-type for the Tier-2 moorings we expect to deploy for the TPOS array. The main air-side enhancements, beyond the DCFS, include all the variables required to compute bulk and radiative fluxes (i.e., radiometers, Tair, RH, Pair Tsea and precipitation sensors). These variables are expected to be on all of the TPOS moorings, so an obvious strategy is to enhance the planned measurements on Tier-2 moorings with stand-alone DCFS. The means, fluxes and waves provided by the DCFS and can be directly used in process studies to force the ocean on Tier-2 moorings and to improve the wind speed and wave-based parameterization found in the bulk algorithms used on the Tier-1 moorings.
