Individual chamber flux measurements from 14 flux whole-canopy shrub plots sampled near the shrub LTER sites at Toolik Field Station, Alaska, summer 2012.

“Flux data” contains the CO2 and water flux data along with the corresponding diffuse light fraction at the time of measurement from the ITEX shrub canopy project taken at Toolik Lake, Alaska in 2012. Each record is a single LiCor flux measurement made with LiCor 6400 photosynthesis system, with associated average pressure, temperature, PAR, water vapor, and other data such as NDVI and LAI measurements taken with a DeltaT SunScan wand under both direct and diffuse light conditions.

"通量数据（Flux data）"收录了2012年于美国阿拉斯加州图利克湖开展的ITEX灌木冠层项目所采集的二氧化碳与水汽通量数据，以及对应测量时刻的散射光占比数据。每条记录为单次采用LiCor 6400光合测定系统完成的LiCor通量测量结果，附带平均气压、温度、光合有效辐射（PAR）、水汽等数据，以及采用DeltaT SunScan手持探头在直射光与散射光两种光照条件下获取的归一化差异植被指数（NDVI）、叶面积指数（LAI）等测量数据。
