KAT –KAS FMI unit measurements in Sodankylä

HR125 FTS observations. Column-averaged abundances of CO2, CH4, N2O, HF, CO, H2O, and HDO are retrieved within Total Carbon Column Observing Network (TCCON). Data access at https://tccondata.org/ Sodankylä TCCON site PI is Dr. Rigel Kivi

Chlorophyll fluorescence measurements are taken using Piccolo and MONI-PAM instruments. Data access: contact Marika Honkanen, email: firstname.lastname@fmi.fi

AirCores. This system measures CO2, CH4, CO reference profiles, the profiles are traceable to WMO standards. Thus, the profiles can be used for comparisons with remote sensing retrievals and model products. contact PI Dr. Rigel Kivi, email: firstname.lastname@fmi.fi
