Long-term observations with solar FTIR spectrometry are being performed at the Zugspitze observatory which is a mid-latitude Station within the NDACC network since 1995. Total columns and vertical profiles of more than two dozens of different trace species are recorded on typically 140 measurement days per year (e.g., H2O, CO, CH4, N2O, NO2, HNO3, O3, HF, HCl, ClONO2, COF2, ...).
Since 2015 the instrument was adapted to perform also measurements in the near infrared for the TCCON Network.
