The AERONET (AErosol RObotic NETwork) program is an inclusive federation of ground-based remote sensing aerosol networks established by AERONET and PHOTONS and greatly expanded by AEROCAN and other agency, institute, and university partners. The goal is to assess aerosol optical properties and validate satellite retrievals of aerosol optical properties. The network imposes standardization of instruments, calibration, and processing. Data from this collaboration provides globally distributed observations of spectral aerosol optical depths, inversion products, and precipitable water in geographically diverse aerosol regimes. Three levels of data are available from this website: Level 1.0 (unscreened), Level 1.5 (cloud-screened), and Level 2.0 (Cloud-screened and quality-assured). Descriptions may be found of program objectives, affiliations, the instrumentation, operational issues, data products, database browser "demonstrat", research activities, links to similar data sets, NASA EOS links and personnel involved in AERONET.

NOTICE TO NON-AERONET INVESTIGATORS: To maintain the integrity of the database and fairness to the individuals who have contributed, use of these data for publication requires an offer of authorship to the AERONET PI(s).

• 25 May 2004 - The AERONET download tool was temporarily disabled from May 11 to May 13 by administrative system changes. These changes were corrected to restore the download tool functionality on May 13.
• 25 May 2004 - The AERONET/PHOTONS workshop was held on the south coast of Spain from May 10 to May 14, 2004. The workshop was located at the facilities of Huelva University (la Rabida campus) in Huelva, Spain, and the experimentation range "El Arenosillo" which is operated by INTA's Department of Earth Observation, Remote Sensing and Atmosphere (Spain).
• 12 January 2004 - Please read the January 2004 AERONET quarterly report for an update on the upcoming project workshop, activities, and new products.
