# Vertical tree air temperature measurements within the canopy of the HJ Andrews Experimental Forest, 2011-2019

## Dataset

- **Database Code:** MV008

- **Title:** Vertical tree air temperature measurements within the canopy of the HJ Andrews Experimental Forest, 2011-2019

- **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.
