Title: | Main Title: NEE measurements in Selhausen (2016) |
Description: | Abstract: The data set includes NEE measurements performed on an agricultural field in Selhausen. NEE was measured at 20 different locations over the whole field. Data collection was at 17 dates during the vegetation period of the sugar beets in 2016. Unless otherwise stated in the files's column "remarks", measurements were in general performed under sunny weather conditions. Translucent, closed chambers (height: 80 cm, area: 1m²) were connected to an Infrared Gas Analyser (Licor Li-8100) to measure NEE. The chambers were mounted on stationary metal frames, which were installed at the 20 locations. 10 sugar beet plants were growing within each frame. Measuring time was always 90 s; the dead band prior of each measurment was 30 s. A short description of important columns of the data file will be given in the following: lin_flux_10plants: NEE flux derived by a linear model provided by Licor File Viewer. exp_flux_10plants: NEE flux derived by an exponential model provided by Licor File Viewer. CV is coefficient of variaition, SE is standard error, and R² is only given for the linear model. T1 is the temperature measured in the chamber during the measurement, and meanCdry is the mean content of CO2 in the chamber during the measurement. |
