Three CMR systems are accessible by Client Partners: CMR Operations, CMR UAT and CMR SIT. Each of these systems is briefly described below. For additional information, click on the associated link.
- CMR Operations (https://cmr.earthdata.nasa.gov)—The CMR Operations system environment is a publically accessible server that houses the production environment. The Data Holdings within this system include Earth Science data that has been made available to the Earth Science Community by the CMR Data Partners. This environment is monitored 24/7, updated with enhancements and fixes on a monthly cycle, and experiences virtually no down time.
- CMR User Acceptance Testing, or UAT (https://cmr.uat.earthdata.nasa.gov)—The UAT environment provides a stable test system to serve the needs of the CMR Data, Client, and Service Partners.The Data Holdings within this system consist of whatever the CMR's Data Partners have made available for their own testing purposes. Any enhancements and fixes that are planned for the Operations Environment are installed in this environment two weeks prior to operations delivery. CMR Partners are encouraged to verify the capabilities when a new release is installed.
- CMR Systems Integration Testing, or SIT (https://cmr.sit.earthdata.nasa.gov)—The SIT system was established in order to facilitate an exchange of ideas and provide an initial testing ground for upcoming capabilities. There is often very little metadata available in this test environment, but it is fully functional. The next operational version is released into this system approximately 1 month before its schedule Operational release date. CMR SIT is a closed, private environment only available to CMR Developers.
