Abstract:
The present atlas is based on the newly available data set known as the Hamburg Ocean At-
mosphere Parameters and Fluxes from Satellite Data (HOAPS), for the global oceans. It pre-
sents the basic fields of air-sea interaction parameters such as sea surface temperature, specific
humidity at air and sea surface temperature, difference in humidity, Dalton number, wind
speed and the air sea fluxes such as latent heat, sensible heat and longwave radiation. The atlas
also provides the hydrological cycle parameters over the global oceans such as evaporation,
precipitation and freshwater flux. The data set covers the period July 1987 to December 1998
and provides the mean monthly, seasonal and annual fields of different variables. It is intended
to provide a climatological data base for scientists and students in the field of climatology, me-
teorology, oceanography, and air-sea interaction. The document describes the various satellite
sensors used and details the method by which the fluxes are derived from those satellite data.
This printed atlas is accompanied by a CD-ROM containing the data of all individual monthly
averages of the considered parameters as well as the figures and this text.
Fields with higher temporal and spatial resolution are also freely available to interested users
for non-commercial scientific research. For details of how to access the Fields see: http://
