SST from AVHRR was derived by Brett Lesh and is mapped as color images
in the plots below.
The surface buoyancy flux directly caclulated from 30 m aircraft legs
is contoured (W/m^2).
On 4 flights, the boundary layer was cloud-free and the SST pattern
aligned with the buoyancy fluxes on the smallest flux scales.
We expect clear boundary layers for stable conditions, when the BL
will tend to be shallower (ie, below the lifting condensation level.)
