OCEAN COLOR
 
 

The Aerosol Robotic Network (AERONET), developed to sustain atmospheric studies at various scales with measurements from worldwide CE-318 distributed autonomous sun-photometers has been extended to support marine applications. This new network component called AERONET – Ocean Color (AERONET-OC), provides the additional capability of measuring the radiance emerging from the sea (i.e., water-leaving radiance) with CE-318 sun-photometers installed on offshore platforms like lighthouses, oceanographic and oil towers. AERONET-OC is instrumental in satellite ocean color validation activities through standardized measurements a) performed at different sites with a single measuring system and protocol, b) calibrated with an identical reference source and method, and c) processed with the same code.

NEWS
 
In agreement with AERONET requirements, the CE-318-T series of instruments is the only one accepted for future AERONET-OC deployments. All current models used in the field will continue to be supported, but replacement of the analog models (Version 4) produced before 2004 is strongly encouraged.
  • AERONET-OC data have been reprocessed on 14 February 2013 after revising the code to account for different regional system configurations. These changes may have led to minor changes in the water-related data products with respect to the previous version.
  • A complete AERONET-OC data reprocessing was performed on 14 February 2012.  In some cases, the removal of the 1020 nm Level 2.0 aerosol optical depth (AOD) prevented the retrieval of Lwn for all wavelengths; therefore, a reprocessing was necessary to recover Lwn values in the 412-870 nm spectral range.  Early evaluation of the reprocessed data indicated an expected increase in the number of Lwn retrievals at some sites and minor changes in the Lwn absolute values.
  • The first AERONET-Ocean Color Workshop was held from 23-24 February 2011, in Greenbelt, Maryland.
