These data describe meteorological measurements on the plateau of James Ross Island [Position: 64.19889°S 57.59761°W]. Specifications of the applied sensors and their mounting heights are described in the attached metadata. All measurements (except of Relative Humidity with one sample measurement per hour) were done with a scanning interval of 10 seconds, and afterwards averaged over one hour. In the case of the sonic ranging sensor and the firn compaction, measurements were done for only 5 minutes per hour due to power consumptions. All data are only filtered by outliers which were easy to discover. Thus, erroneous measurements (e.g., in the case of the sonic raning sensor), can still be part of the data.
