A 7.5-Year Dataset of SSM/I-Derived Surface Turbulent Fluxes Over Global Oceans

摘要: The surface turbulent fluxes of momentum, latent heat, and sensible heat over global oceans are essential to weather, climate ocean problems. Wind stress is the major forcing for driving oceanic circulation, while Evaporation a key component hydrological cycle budget. We have produced 7.5-year (July 1987-December 1994) dataset daily, individual monthly-mean climatological (1988-94) from measurements Special Sensor Microwave/Imager (SSM/I) on board US Defense Meteorological Satellite Program F8, F10, F11 satellites. It has spatial resolution 2.0x2.5 latitude-longitude. Daily derived daily data SSM/I winds specific humidity, National Centers Environmental Prediction (NCEP) sea temperatures, European Centre Medium-Range Weather Forecasts (ECMWF) air-sea temperature differences, using stability-dependent bulk scheme. retrieved instantaneous air humidity (with 25-km resolution) IS found be generally accurate as compared collocated radiosonde observations oceans. wind speed (latent flux) F10 -encrally smaller (larger) than those SSM/I. appears slightly better retrieval accuracy This difference may due orbital drift satellite. stresses SSM/Is show useful verified against research quality in si -neasurerrients (IMET buoy, RV Moana Wave, Wecoma) western Pacific warm pool during TOGA COARE Intensive observing period (November 1992-February 1993). 1988-94 seasonal-mean input variables FS reasonable patterns related seasonal variations atmospheric general circulation.
