AERONET deploys ground-based remote sensing providing observations of spectral aerosol optical depth (AOD), inversion products, and precipitable water in diverse aerosol regimes and adopts Sun and Lunar scenarios for collecting spectral measurements of the atmosphere (https://aeronet.gsfc.nasa.gov/). In Heraklion, an AERONET System (Aeronet #525) is installed, including a Cimel Multiband Photometer, and operates since January 2021 at the city center, while its data products are accessible via the AERONET Website
