资源简介：
\"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. This data is also recorded every 30 min. Thus, the 30 min file contains data from 2009 to present. Data was recorded in a CR10x Campbel scientifix data logger until June 2014, where the data logger was changed to a CR1000. \"
