Determination of Longwave Heat Flux at the Air-Sea Interface Using Measurements from Buoy Platforms

摘要: Abstract A theory for pyrgeometer operation is utilized determining downwelling longwave radiation. Errors in radiation measurements are due to differences body and dome temperatures compared that of the atmosphere. Additionally, incident shortwave fluxes may be important. Using present along with laboratory field observations, it appears heat can measured errors less than 6 W m−2. Longwave flux observations from surface buoys deployed four different oceanic regions suggest 1) incoming repeatable, 2) uncertainties radiometer calibration significant systematic, 3) pyrgeometers affected by direct indirect solar heating. hybrid measurement method determination net at air-sea interface described. The authors recommend improvement procedures as well development a radiomete...
