On 25 July 2002, a new SGI Origin 3800 system named chinook was made available for users. The new machine was binary compatible with ute, the Origin 2000 it replaced, and had the same number of processors but twice the clock speed, four times the memory, and more than double the disk capacity.

Chinook had 128 500-MHz R14000 processors, a clock speed of 500 megahertz, 65 gigabytes of distributed shared memory, and 580 gigabytes of disk space. It was fitted with a HiPPI connection to the Mass Storage System and gigabit Ethernet to NCAR networks.

Also included in the chinook complex was an 8-processor SGI Origin 2100 named chinookfe, which functioned as a front end to chinook.

The chinook complex was allocated as part of the Climate Simulation Laboratory (CSL).

Both chinook and chinookfe were decommissioned on 30 August 2004, as SCD SCD investigated newer compute servers with better price performance.

The National Science Foundation, NCAR's primary sponsor, funded the computer through a special award from its Division of Atmospheric Sciences, with research support from the NSF Office of Polar Programs.
