Public domain sensor data is available for download on Globus. The TERRA-REF sensor data portal provides a web interface that allows you to browse and search these data (though it may be slow, and there are lots of files!).

Additional meta-data and unpublished (and unchecked!) data can be acccessed through the TERRA REF phenotype database. After logging in, you will be able search and download agronomic and trait data.

Access to the raw and derived genomics data products requires registration with one or more services including Globus, CyVerse, CoGe, and/or the NDS Analysis Workbench. For more information, see the documentation. Access genomics data on CyVerse or Globus.
