NSF Unidata academic community members can retrieve archived satellite data from the University of Wisconsin-Madison's SSEC.

NSF Unidata regional workshops aim to help the atmospheric science community understand and use the Python ecosystem.

NSF Unidata tools like the IDV help visualize many types of geoscience data. Here an image of the COSMIC data set shows individual soundings derived from GPS radio occultation.
