LAPUP has a wide range of research instruments for measuring the optical properties of clouds and aerosols, solar radiation, as well as key meteorological parameters. It also maintains substantial computing infrastructure for running simulations and analyzing large datasets.

At LAPUP, a fully equipped meteorological station operates, measuring temperature, humidity, atmospheric pressure, wind speed and direction, precipitation, and soil moisture. A similar meteorological station also operates at the University of Patras facilities in Koukouli.

A fully equipped radiometric station operates at LAPUP, featuring pyranometers, a pyrheliometer, and spectrophotometers for measuring direct, diffuse, global, and tilted solar irradiance in the 300–1100 nm range, as well as a pyranometer calibration unit.

LAPUP operates extensive sensor networks measuring PM1, PM2.5, and PM10 across various cities in Greece, and has developed a suite of calibration, quality-control, and data-analysis algorithms. These are supported by a reference instrument that measures particulate concentration in 31 size channels (GRIMM 365).

LAPUP operates systems for digital imaging of the sky dome (Mobotix cameras) and has developed a series of algorithms to estimate the optical properties of aerosols and clouds.

LAPUP’s equipment includes computing resources for running solar-radiation transfer models and weather-forecasting models, as well as for the statistical processing of their outputs.
