Other parameters which are related to and will benefit from the availability of the above
mentioned set of parameters but might need additional information from other sources are
parameters related to air-sea interaction such as: latent and sensible heat fluxes, longwave
radiative heat flux, momentum flux, surface rain rate, sea ice extent, type and coverage, oceanic
particle flux (biogenic and lithogenic), oceanic white-cap coverage and ocean-atmosphere gas
exchanges.
