High-frequency wind (u, w, v, Ts) and gas concentration measurements of CO2 and H2O over an agricultural field in Braunschweig, Germany
Description
This dataset contains high-frequency eddy covariance (EC) measurements over a flat agricultural field at the Thünen Institute in Braunschweig, Germany (52.30° N, 10.45° E).
The data collection period spanned 77 days in the year 2020 split into three files
| BS2020_06.rds | June 11 to July 15 |
| BS2020_10.rds | October 1 to November 10 |
| BS_2020_07_subset.rds | July 11 to July 25 |
Included in the dataset are 3D wind velocity data, recorded using a uSonic-3 Class A sonic anemometer from Metek GmbH. Additionally, the dataset provides gas concentration measurements for carbon dioxide (CO2) and water vapor (H2O), captured using an LI-7500A open-path infra-red gas analyzer from LI-COR Biosciences GmbH, Germany.
Variables in the dataset
| Variable Name | Description | Units |
|---|---|---|
| time | Unique time stamp (POSIXct format) | Seconds since Unix epoch |
| CO2 | Wet molar density of carbon dioxide | µmol m⁻³ |
| H2O | Wet molar density of water vapor | mmol m⁻³ |
| Ts | Sonic temperature | Kelvin |
| u, v, w | 3D wind velocity components | m s⁻¹ |
The dataset is in RDS format (version 3), compatible with R version 3.5.0 or higher.
RDS is a binary file format native to the R programming environment
