Type 1 data are available to all interested parties with few or no restrictions other than those stipulated in the Data Users Agreement.  Type 1 data sets include those routinely collected by either LTER Co-PI's or associated investigators that are crucial to multiple research projects (e.g., climatological, hydrological and similar data). 

These data will be made available within two years of collection with few or no restrictions other than those stipulated in the DATA USERS AGREEMENT. In addition, all Type 2 data sets automatically will be migrated to Type 1 status after two years has elapsed from the completion of the project.  For more information, refer to Coweeta Data Management Policies.

Type 2 data are available only with written permission from the Co-PI(s) directing this segment of LTER research (see Data Users Agreement). We require this permission for two reasons: 1) to ensure that the data being requested are appropriate for the purposes stated by the requesting investigator, and 2) to ensure that the PI has had sufficient time to process, analyze, synthesize and publish results obtained from these data.

A data set will be maintained under Type 2 status for a maximum of two years after completion of the project, after which time it will immediately be migrated to Type 1 status. A project is completed when the PI responsible for this segment of the research determines that all planned publications have been obtained from the data set. The PI will notify the Data Manager when a project has been completed
