The seasonal progression of global vegetation is driven by the tilt of the Earth's rotational axis and its annual orbit around the Sun. In turn, global seasonality drives major changes in important environmental factors such as global atmospheric carbon dioxide concentrations.

This video focuses on the Land Processes Distributed Active Archive Center’s (LP DAAC) Data Pool and DAAC2Disk. The Data Pool provides direct access to the publicly available data products from the LP DAAC archive. DAAC2Disk enables users to download multiple data products from the Data Pool using a web-based interface, as a script executed from the command line.

Tom Loveland, research scientist with the USGS Earth Resources Observation and Science Center, explains how he uses data — both past and present — to help scientists, natural resource managers, and the public better understand how the face of the planet is shifting and what that change means.
