15 January 2014 - MODIS Rapid Response images are not available between January 2011 and mid-December 2013 (More Information)


The AERONET (AErosol RObotic NETwork) program 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. The program provides a 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. Aerosol optical depth data are computed for three data quality levels: Level 1.0 (unscreened), Level 1.5 (cloud-screened), and Level 2.0 (cloud-screened and 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 to Version 2.0 (fully released in July 2006) and are available from the AERONET and PHOTONS web sites. Version 1 data may be downloaded from the web site through 2006 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.

  • The Distributed Regional Aerosol Gridded Observation Networks (DRAGON)-KORUS-AQ instrument deployment has been established in South Korea, Japan, and China from 1 April to 31 July 2016. The network will be strategically located to take advantage of KORUS-AQ in situ and airborne resources from mid-June 2016.

  • 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.

  • Version 3 processing and evaluation begins October 1. The Version 3 processing is now officially in evaluation mode that includes a beta version of the AOD and inversion products. We expect a final release in early 2016. The initial beta release is available via the AERONET web service. These Version 3 beta data products are for evalution and not for publication.
