Atlas of surface marine data 1994, volume 4: Anomalies of fresh water fluxes

This atlas presents objectively analyzed fields of surface marine climatology and anomalies of evaporation, precipitation, constrained evaporation minus precipitation, constrained buoyancy flux, and zonal and meridional surface moisture flux over most of the global ocean. These revised monthly mean fields are derived from individual observations in the Comprehensive Ocean-Atmosphere Data Set (COADS) from January 1945 to December 1989 and are analyzed on a 1-degree by 1-degree global grid. Corrections have been made to reduce wind speed bias associated with an erroneous Beaufort equivalent scale and to consider missing Present Weather observations, from 1982 on, as representing clear weather if a cloudiness measurement is present. In addition to seasonal anomalies, maps of seasonal climatology, standard deviations, and the number of observations are presented for each quantity.
