Hubbard Brook Experimental Forest: Flux Tower Fast and Slow Data

General Information

Data Package:
Local Identifier:	knb-lter-hbr.241.1
Title:	Hubbard Brook Experimental Forest: Flux Tower Fast and Slow Data
Alternate Identifier:	knb-lter-hbr.241
Alternate Identifier:	DOI PLACE HOLDER
Abstract:	Data collected from the Hubbard Brook Flux Tower starting in August 2016 that is also uploaded to the Ameriflux website under site name US-HBK. These data are from a suite of sensors installed on the 110 ft. tower and in the ground below the tower. Fast data is collected at 10Hz and is processed into 30min time steps using Licor’s Eddy Pro software. Slow data are averaged at 30 minute intervals and are included with this dataset.
