These are brief descriptions and links to some long-term data sets
of various types which may be useful in decadal climate variability
research and applications. This is by no means a complete list and
new contributions are always welcome. The only criterion used in
including data sets here is that the time series should be at least
40 years long. These data sets have not been checked for quality
or continuity nor has the brief description with each data set checked
for accuracy or clarity.
