ABSTRACT
Different kinds of geophysical data sets are used by the Climate dynamics
group at CSM to carry out research and diagnosis in modeling studies. These
data sets come from different observations (satellite, buoys, ships,
etc) or model outputs (GCM and transport models) with different spatial
and time resolutions. This table gives a summary of these data sets and sample plots showing
some current research. The links under variables column display samples plots for each data set.
