M4_30min

M4 is located on a well drained Cassiope heath, about 150 meters north of the 'Climate station' (operated by ClimateBasis).
In 2009 NDVI sensors were installed and data recorded every 30 min. In 2014 temperature probes were installed in different depths in the soil.
NDVI measurements were terminated in 2014.
Data was recorded using a CR10x Campbel scientific data logger until June 2014, where the data logger was changed to a CR1000.

M4 位于排水良好的岩须属（Cassiope）灌丛生境中，距离由ClimateBasis运营的"气候站"以北约150米处。2009年部署了归一化差值植被指数（Normalized Difference Vegetation Index, NDVI）传感器，每30分钟记录一次数据；2014年在土壤不同深度布设了温度探针。同年，NDVI测量工作终止。2014年6月前，数据均通过CR10x型Campbell Scientific数据采集器记录，之后更换为CR1000型数据采集器。
