Statement of Need (SON)

Project: Procurement of eddy covariance towers, including all instruments and tower parts as described below.

GENERAL INFORMATION

1.0 Scope of Work: The US Dairy Forage Research Center is requesting bids for purchase of two new eddy covariance tower systems, each capable of continuously monitoring carbon dioxide and water vapor exchange, energy balance, and micrometeorology. Specifications for the purchase are itemized below.

2.0 Background: Research programs at the US Dairy Forage Research Center are interdisciplinary, and include assessment of the economic and environmental performance of crop-dairy livestock systems. Research priorities include evaluation of farm greenhouse gas emissions and opportunities for climate mitigation through land cover change and improved management practices. Carbon dioxide and water flux monitoring equipment is needed to expand existing research on the impacts of cropping systems and field management practices on field carbon balance and soil organic carbon. The new towers will allow for two new fields to be instrumented and will expand the range of crop management practices that can be evaluated.
