Abstract
The SP-9 and SPM multiwavelength sun photometers are described and briefly characterized. The SP-9 sun photometer is designed for year-round monitoring of the spectral atmospheric transparency in the wavelength range 0.3–2.2 mm in the regional network of stations. To implement the automatic measurement mode (unattended by operators), the instrument includes solar sensor, automatic sun pointing/tracking system, built-in GPS receiver and flash drive, and sensors of meteorological parameters. The SPМ portable photometer is a simplified version of SP-9 and is designed for the atmospheric transparency measurements under mobile conditions.
