ICOADS (and earlier COADS) products can be distributed without restriction.
If the product is modified (e.g., subsets of statistics or of observed data
fields) for redistribution, this should be clearly documented, and we request
that the location of the original data, at the US National Center for
Atmospheric Research and US National Oceanic and Atmospheric Administration,
be specified.  Furthermore, we ask that the title of the data product should
indicate that it was "derived" from ICOADS, not that it "is" ICOADS.

----------

The original COADS project, and the continuing US contribution toward the new
international database, ICOADS, is the result of a cooperative project between
the National Oceanic and Atmospheric Administration (NOAA)--specifically its
Earth System Research Laboratory (ESRL), its National Climatic Data Center
(NCDC), and the Cooperative Institute for Research in Environmental Sciences
(CIRES, conducted jointly with the University of Colorado)--and the National
Science Foundation's National Center for Atmospheric Research (NCAR). The NOAA
portion of ICOADS is partially funded by the NOAA Climate Program Office (CPO).
