November 7, 2006 Subject: Re-release of Version 2 Inversion Quality Assured Data Products Dear Colleagues, The Version 2.0 Level 2 inversion products are now released and available through the AERONET website and linked through the PHOTONS website and associated data access tools. Please read the AERONET home page for descriptions of the Version 2.0 Level 2 products and analysis of this version. Error bars are currently being recomputed and will be added to the data set in a few weeks. Version 2 Level 1.5 is currently being reprocessed and will be available in a few weeks. Version 1.0 will continue to be supported through 2007. Please note that the Version 2.0 Level 2 database retains the 'recommended' criteria approach for certain products such as AOD440>0.4 for SSA. When the errors bars become available, the analyst will have the option of selecting the acceptable error limits (+/-0.03 for SSA for example) to subset the 'recommended' level 2 database. This will be discussed in detail when the error bars become available. Regards, Brent Holben
