CHAP: Eligibility

University use of CISL resources is intended to support research in the atmospheric and related sciences by scientists and graduate students at U.S. universities. The emphasis is toward extensive projects beyond the scope of university computing centers. Such larger-scale projects are reviewed by the CHAP. There are three primary eligibility criteria.

This section describes the conditions under which applicants are eligible to apply for NCAR computing resources.


A prime mission of CISL is to support U.S. university atmospheric science. However, eligibility has been extended to include certain other U.S. educational institutions and non-profit research organizations.

Eligible researchers incur no costs for use of CISL resources. Normally, CISL does not support research groups in federal agencies.


National Science Foundation grants

Researchers can apply for NCAR computing time under an associated NSF grant as long as their proposed computing lies appropriately within the scope of the grant. The NSF is kept informed to ensure appropriate use of CISL resources. Requests above the defined "small" size must be submitted for review at the semi-annual CHAP meetings. CISL reviews small requests internally.

Resources for unsponsored graduate students and postdocs

A one-time NCAR computing grant is available to qualifying graduate students, postdocs, and new faculty.

See Small Allocation Requests for details.

Non-NSF funding

Due to high demand for CISL resources at this time, CISL is unable to provide computing support to atmospheric scientists who have funding from non-NSF sources.

Atmospheric and related sciences

Atmospheric science attempts to understand the total behavior of the earth's fluid envelope on all scales ranging from microscopic processes to global motions. Since this system is bounded by the oceans and solid earth and driven primarily by solar radiation, some areas of ocean science, solid earth science, solar physics, and astrophysics are also included.
