Dataset for 'Using Metal Oxide Gas Sensors for the Estimate of Methane Controlled Releases: Reconstruction of the Methane Mole Fraction Time-Series and Quantification of the Release Rates and Locations'

This dataset is associated with the research entitled: 'Using Metal Oxide Gas Sensors for the Estimate of Methane Controlled Releases: Reconstruction of the Methane Mole Fraction Time-Series and Quantification of the Release Rates and Locations’. It contains raw data from six low-cost sensor loggers and one anemometer, collected during an experiment consisting of a series of controlled releases conducted in October 2019 at the TADI (TotalEnergies Anomaly Detection Initiative) platform.

Dataset Structure:

- `time`: Timestamp, marking the exact time the data was collected.
- `CH4`: Methane concentration measured by the reference instrument in parts per million (ppm).
- `2611C`: Voltage variation measured by the Figaro TGS 2611C-00 MOS sensor in volts (V).
- `2600`: Voltage variation measured by the Figaro TGS 2600 MOS sensor in volts (V).
- `2611E`: Voltage variation measured by the Figaro TGS 2611E-00 MOS sensor in volts (V).
- `RH_DHT22`: Relative humidity measured by the DHT22 sensor in percentage (%).
- `RH_SHT75`: Relative humidity measured by the SHT75 sensor in percentage (%).
- `T_DHT22`: Air temperature measured by the DHT22 sensor in degrees Celsius (°C).
- `T_SHT75`: Air temperature measured by the SHT75 sensor in degrees Celsius (°C).
- `T_BMP180`: Air temperature measured by the BMP180 sensor in degrees Celsius (°C).
- `T_BMP280`: Air temperature measured by the BMP280 sensor in degrees Celsius (°C).
- `P_BMP180`: Atmospheric pressure measured by the BMP180 sensor in pascals (Pa).
- `P_BMP280`: Atmospheric pressure measured by the BMP280 sensor in pascals (Pa).
- `Release`: Number of the controlled release.
