ABSTRACT:
	Vertical air temperature from 11 trees in the Andrews Forest has been collecting beginning in 2011. The trees are at a variety of elevations and are of various species and ages. The 11 trees were selected form the H.J Andrews phenology study air temperature network (MS045). This study examines air temperatures at multiple heights in each tree. The first sensor is at 1.5 m and subsequent sensors measure every 5 m up the tree. Each sensor includes a light (illumination) sensor, which can be used to assess the value of the data. This is not a measurement of the actual light conditions.

ENTITY TITLES:
1	Fine temporal resolution air temperature and light intensity data (Jul 11 2011 - Jun 30 2019)	METADATA	DATA
RELATED MATERIALS:
	HOBO workflow - Includes PDF files that describe the steps from field deployment through the production of raw data, which is input into the Python code, instructions to offload data from the shuttle, and download data from the logger with the shuttle.
	Python workflow for vertical tree data - Includes instructions on how to run the Python code for vertical tree data, including yaml and wheel files, which can be adjusted by the user to change the flagging of the data, and the definition of flags used in the Python QAQC file.
	Vertical tree HOBO information - Information on each site with an instrumented tree (includes coordinates, elevation, number of loggers, height of highest logger, tree species and dbh)
	Sunrise-sunset table - Table by day of year for sunrise and sunset times in Pacific Daylight Time
	hja_hobo_clean Python program - The repository that hosts the code needed to process, flag and clean HOBO-collected data records from the H.J. Andrews Experimental Forest.
