NCAR Data Search

Looking for data, but don't know where to start? Visit to quickly find data from any of NCAR’s data service providers.


Research Data Archive (RDA)

The Research Data Archive (RDA) contains a large, diverse collection of meteorological and oceanographic observations, operational and reanalysis model outputs, and remote sensing data sets to support atmospheric and geosciences research.


Geoscience Data Exchange

GDEX distributes and preserves open-access data from diverse sources, including data that underlie publications by NCAR staff, and data from selected external NSF-funded projects and facilities.


CMIP Analysis Platform

Among the data services CISL provides is the CMIP Analysis Platform, which gives researchers convenient access to Coupled Model Intercomparison Project climate data for their work on NCAR's analysis and visualization systems.


Study the classics

NCAR’s classic math libraries are a geophysics mainstay that includes the Fortran libraries FFTPACK, FISHPACK, MUDPACK, and SPHEREPACK.

These libraries, developed at NCAR from 1970 to 1990, are still in use thanks to the value they bring to the scientific community.
