The Harwell TCCON observatory

Damien Weidmann, Richard Brownsword, and Stamatia Doniki

Abstract. The Harwell observatory, located in Oxfordshire, UK, now part of the Total Carbon Column Observatory Network (TCCON), has been performing ground-based remote sensing of averaged dry columns of atmospheric greenhouses since September 2020. Measurements are performed through near infrared and short wave infrared high-resolution spectroscopy of the atmosphere's transmission in solar occultation viewing mode, following the TCCON methodology. We report on the development, the measurements, and the performance of the observing system installed at Harwell. The hardware and software are described and characterized, as well as the outputted data quality, based on the four year data record collected so far. The Harwell site is demonstrated to produce data of high quality, well in line with the requirements for the TCCON infrastructure.

Short summary
The development and characterization of a ground-based system measuring column average concentrations of greenhouse gases is described, as well as the corresponding four years dataset recorded at Harwell, Oxfordshire, UK. The system, based on high-resolution Fourier Transform spectroscopy of atmospheric transmission, fulfills the requirements established by the Total Carbon Column Observatory Network (TCCON) to contribute to the international greenhouse gas observing infrastructure.
