MISSION
 

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) and is greatly expanded by networks (e.g., RIMA, AeroSpan, AEROCAN, and CARSNET) and collaborators from national agencies, institutes, universities, individual scientists, and partners. Fo 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 network imposes standardization of instruments, calibration, processing and distribution.

AERONET collaboration provides globally distributed observations of spectral aerosol optical depth (AOD), inversion products, and precipitable water in diverse aerosol regimes. Version 3 AOD data are computed for three data quality levels: Level 1.0 (unscreened), Level 1.5 (cloud-screened and quality controlled), and Level 2.0 (quality-assured). Inversions, precipitable water, and other AOD-dependent products are derived from these levels and may implement additional quality checks.

The processing algorithms have evolved from Version 1.0 to Version 2.0 and now Version 3.0. The Version 3 databases are available from the AERONET and PHOTONS web sites. Version 2 data may be downloaded from the web site through 2018 and thereafter upon special request. New AERONET products will be released as new measurement techniques and algorithms are adopted and validated by the AERONET research community. The AERONET web site also provides AERONET-related news, a description of research and operational activities, related Earth Science links, and an AERONET staff directory.

5 January 2018


We are pleased to announce the following AERONET Version 3 (V3) database updates:

  • V3 Level 2.0 (Quality Assured) Aerosol Optical Depth (AOD) including Angstrom Exponent and Water Vapor database is now available.

  • V3 Level 2.0 (Quality Assured) Spectral Deconvolution Algorithm (SDA) retrieval products (fine mode AOD , coarse mode AOD, and fine mode fraction of AOD) database is now available.

  • V3 web service now includes a link to download sky scan measurements such as almucantar, hybrid, and principal plane scenarios.

  • V3 Level 1.5 and Level 2.0 Almucantar inversion database available 11 January 2018.

  • Version 2 Level 2.0 AOD, SDA, and Inversion databases are expected to be maintained concurrently for 1 year.

  • CE318-T Sun-Sky-Lunar spectral photometer is accepted for AERONET use. Extensive testing of the new model Cimel photometer has been completed and is now fully integrated into the AERONET network.

    The new model is essentially a new control box that has all the functionality of the current CE318 photometers.  It is fully compatible with the existing robots and the latest Version 5 sensor heads (with an upgrade kit).  We note the following characteristics:

    --Improved solar tracking accuracy and operational range
    --Micro-stepping: faster and smoother robot response
    --Enhanced measurement scenarios yet data sets are compatible with historic database
    --Onboard data storage prevents data loss GPS time and location stamped data
    --Communication via serial, USB, cellular and DCS satellite
    --Lunar measurements

    AERONET will no longer accept previous models as new entries into the network. All current models used in the field will continue to be supported but replacement of the analog models (Version 4) produced before 2004 is encouraged.
