TECHNIQUE ESTIMATING SEA SPRAY PRODUCTION RATE FOR GLOBAL CLIMATE MODELS FROM SATELLITE-DERIVED MEASURES OF OCEANIC WHITECAP COVERAGE
By combining laboratory-determined values for the number of sea spray droplets, per increment of droplet radius, that are produced during the decay of an oceanic whitecap of initial unit surface area, and values determined from both laboratory experiments and field observations for the e-folding tim...

| Sumario: | By combining laboratory-determined values for the number of sea spray droplets, per increment of droplet radius, that are produced during the decay of an oceanic whitecap of initial unit surface area, and values determined from both laboratory experiments and field observations for the e-folding time associated with the decay of individual oceanic whitecaps, with satellite-derived measures of the fraction of the sea surface covered at any instant by spilling wave crests (Stage A whitecaps), the number of sea spray droplets, per droplet radius increment, that are produced per unit time, per unit area of the ocean surface, can be estimated. This sea spray aerosol source function can be incorporated in any global climate model where the role of spray droplets in influencing maritime cloudiness, in affecting the over-ocean radiative balance, and in contributing to the sea-air moisture flux, need be explicitly parameterized |
