The Geophysical Fluid Dynamics Laboratory is located on the Forrestal Campus of Princeton University.
I. National Climate Data Center (NCDC) of the National Atmospheric and Oceanic Administration (NOAA)
Data and information for Climate, Geophysics, Ocean, and Coastal
III. National Center for Atmospheric Research (NCAR)
"NCAR fosters scientific research by providing the scientific community with timely, easy-to-access data collections. Data sets include information collected from research facilities and tools, as well as information from climate and weather models created and compiled by NCAR scientists and those in our science community." From the "Data Sets" page.
IV. Create a monthly or seasonal time series of climate variables at NOAA's CDC.
V. ORNL DAAC Data Catalog (holdings), Distributed Active Archive Center for biogeochemical dynamics, Oak Ridge National Laboratory. All data sets are free. A semiannual newsletter announces the latest data sets relevant to climate change.
VI. CLIMOD Northeast Regional Climate Center at Cornell. Available mainly by subscription, because its purpose is: CLimate Information for Management and Operational Decisions
