Terra’s Dataset Library includes a number of integrated datasets, many of which have individualized Data Explorer interfaces, useful for generating and exporting custom cohorts. If you click into a dataset and have the proper permissions, you'll be able to explore the data. If you don't have the necessary permission, you'll be taken to a page that tells you whom to contact for access.
The resources linked below provide guided instructions for creating custom cohorts from the data library and importing them to your workspace, and using a Jupyter notebook to interact with the data: Article: Accessing and analysing custom cohorts with Data Explorer Video: Notebooks Quickstart walkthrough Workspace: Notebooks Quickstart workspace
