SMAPVEX 19-22 Millbrook Project Information

This project was initiated in 2019 and completed in 2022. For this campaign, sites were based in the Millbrook NY area, approximately centered at Cary Institute of Ecosystem Studies and in Massachusetts approximately centered at Harvard Forest. A third site for part of the campaign was centered at a Boreal Ecosystem Research and Monitoring Sites (BERMS) in Saskatchewan. Each site had approximately 25 sub-sites located within a 30x30 km grid that coincided with the path of the SMAP satellite. At each sub-site, stations were installed to collect soil moisture, soil temperature, air temperature and canopy photo data. Each station had 3 soil moisture and temperature sensors placed vertically, at 5 cm below surface and 5 cm below mineral soil. Also, each station had an air temperature sensor and an upward facing camera for phenology. In addition to these stations, at six sites, Teros water content sensors were installed in trees and at 4 sites sapflow sensors were placed in trees. During April and August 2022, vegetation and intensive manual measurements were made at each of the 25 sites. In addition, several remote sensing datasets were collected.
