Data from the Butler green roof reaches from 2013 to the present and is available for download.

The Hydrometeorology Program focuses on measurement, analysis and modeling of atmospheric and land surface processes tied to the hydrologic cycle. A special interest of the group centers on hydrometeorological processes in the urban environment. The Hydrometeorology Lab maintains five stations around Princeton University campus. The data from these stations are used by students and professors to gain insight into the impact of suburban development on different environmental paramters. These real-time data loggers act as part of the Campus as a Lab initiative. Data collected is used in on-going research of the Butler Green Roofs and Washington Stream Restoration.
