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.
