Multiple Species

Y. Té and P. Jeseck (Sorbonne Université, MONARIS UMR8233) - Bruker IFS-125 HR (maximum resolution of 0.0035 cm-1) installed at Pierre et Marie Curie Campus of Sorbonne Université in 2007. Located in the center of Paris downtown, atmospheric observations become more regularly since 2011. Multiple species (column and profile) retrieval using mainly SFIT4 (possible use of PROFFIT9). The relatively flat surroundings of Paris are conductive to satellite validation. The FTIR measurements are complemented by other Qualair platform instrument observations.

W. Wang (AIOFM) and C. Liu (USTC)–Measurements using a Bruker IFS 125HR (resolution up to 0.001 cm-1) began in 2015. The observation site is located in a suburb of Hefei city, Anhui province, China. Retrieval algorithm is SFIT4 (V.0.9.4.4).

A. Pazmino, F. Goutail (LATMOS-IPSL) and V. Amelie (SMA) – Mini-SAOZ system operated since September 2017. It is the modernized and lightened version of the SAOZ instrument.

A. Pazmino, F. Goutail (LATMOS-IPSL) and Nis Jepsen (DMI) - SAOZ system for NO2 and ozone operated since September 2017. The instrument previously operated at Thule station (1990-2016). New reference spectrum created and retrieval updated following UVVIS WG recommendations.

A. Bais, D. Karagkiozidis (LAP-AUTH) – Zenith measurements of NO2 and ozone derived from two UV/Vis miniature CCD spectrometers (Avantes) operating at Thessaloniki, Greece. Data are available since 2018 (Phaethon 7) and 2020 (Phaethon 8). Phaethon 7 was validated during the CINDI-2 campaign.
