Meteorological data collected at the Abri Haut station

The station is connected to a 230V power supply and data is transmitted daily in ascii file format. The configuration of the meteorological measuring station includes a Campbell Scientific datalogger for storing data at a time step of 10 minutes, and for controlling the sensors. The CR1000X has been in operation since May 9, 2023, replacing the old CR10X, whose commissioning date is unknown. The temperature and humidity sensor used is a Vaisala model HMP45C, whose commissioning date is unknown. The wind speed sensor is R.M. Young model 05103, in operation since July 11, 2023, replacing the old anemometer of the same model, whose commissioning date is unknown. The radiation sensor is a Kipp Zonen model CM6B, whose commissioning date is unknown. Finally, precipitation is measured by the Précis-Mécanique R5-302 b rain gauge in operation since September 09, 2020, replacing a Précis-Mécanique 3020/1 rain gauge of unknown commissioning date, itself replacing a Précis-Mécanique R5-302 b rain gauge of unknown commissioning date. Data are analyzed and qualified using python and/or R. Device documentation can be found on the OHGE website: https://ohge.unistra.fr/. Historical background: These data have been acquired since 1986, thanks to the involvement of many people - technicians, engineers and researchers - who have worked to ensure the continuity and quality of the measurements, both in the field and in the laboratory. We cannot name them all here. The Observatory was initiated by research projects conceived and led by Bruno Ambroise, Bertrand Fritz and then Anne Probst.
