Columnar Aerosol Optical Properties by sun-lunar photomery at BAE Juan Carlos I

Photometers, measuring Sun and Moon direct irradiance and sky radiances at several wavelengths, are able to provide accurate information about aerosol and water vapour properties in the atmospheric column. The AERONET (AErosol RObotic NETwork) project is a federation of ground-based remote sensing aerosol networks established by NASA and PHOTONS (PHOtométrie pour le Traitement Opérationnel de Normalisation Satellitaire; Univ. of Lille 1, CNES, and CNRS-INSU). For more than 25 years, the project has provided long-term, continuous and readily accessible public domain database of aerosol optical, microphysical and radiative properties for aerosol research and characterization, validation of satellite retrievals, and synergism with other databases. The are three levels of data: Level 1.0 (unscreened), Level 1.5 (cloud-screened and quality controlled), and Level 2.0 (quality-assured). Level 1.0 and 1.5 are available in near real time.
We have created the “Juan_Carlos_I_base” site in Livingston Island, included in AERONET. The public domain database can be easily accessed by https://aeronet.gsfc.nasa.gov/
Variables than can be found in the database: Aerosol Optical Depth (at 340, 380, 440, 500, 675, 870, 1020, 1640 nm), Ångström Exponent, Water vapor column, single scattering albedo (at 440, 675, 870 and 1020 nm), asymmetry factor (at 440, 675, 870 and 1020 nm), refractive indexes (at 440, 675, 870 and 1020 nm), sphericity fraction, volume size distribution, effective radius, columnar volume concentrations, phase function, zenith sky radiance (at 380, 440, 675, 870 and 1020 nm). A complete description of all these variables can be found in https://aeronet.gsfc.nasa.gov/.
