Abstract
Abstract. This paper describes the laboratory facilities at the Finnish Meteorological Institute – Arctic Research Centre (FMI-ARC, http://fmiarc.fmi.fi). They comprise an optical laboratory, a facility for biological studies, and an office. A dark room has been built, in which an optical table and a fixed lamp test system are set up, and the electronics allow high-precision adjustment of the current. The Brewer spectroradiometer, NILU-UV multifilter radiometer, and Analytical Spectral Devices (ASD) spectroradiometer of the FMI-ARC are regularly calibrated or checked for stability in the laboratory. The facilities are ideal for responding to the needs of international multidisciplinary research, giving the possibility to calibrate and characterize the research instruments as well as handle and store samples.
Highlights
The location of the Finnish Meteorological Institute – Arctic Research Centre (FMI-ARC) (67.367◦ N, 26.629◦ E) is ideal for atmospheric and environmental research in the boreal and sub-Arctic zone

The optical laboratory facilities at the FMI-ARC comprise a control room, a dark room, a facility for biological studies, and an office. They are ideal for calibration and characterization of optical instruments such as spectroradiometers, broadband and multichannel radiometers, and aurora cameras
Summary
We present the optical laboratory facilities of the FMIARC and focus on the measurements of optical instruments used for stratospheric and climate research at the FMI-ARC. The NILU-UV instruments have been set up to measure in the peatland field experiment and forest experiment of the Finnish Ultraviolet International Research Centre (FUVIRC) during the summers of 2002–2011 (Lakkala et al, 2016). The quality control and quality assurance of the measurements require monitoring of the stability of the instruments using regular lamp tests, which need to be performed in an appropriate optical laboratory. This work describes the characteristics of the optical laboratory facilities at the FMI-ARC and shows typical measurement protocols for the above-mentioned instruments
