The Atmospheric Science Data Center (ASDC) at NASA Langley Research
Center in collaboration with the MISR Science Team announces the public
release of a new Model-Derived Global Aerosol Climatology for MISR
Analysis Data Set ("Clim-Likely").

The "Clim-Likely" data set was derived from 'typical-year' aerosol
transport model results, and was developed as an initial step in
identifying a range of components and mixtures for the MISR Standard
Aerosol Retrieval Algorithm climatology, and as one standard against
which to compare MISR aerosol air mass type retrieval results.

Six component aerosols included in the model were medium and coarse mode
mineral dust, sulfate, sea salt, black carbon, and carbonaceous
aerosols. Values reported are percent of total column mid-visible
aerosol optical depth (AOT) for each component, total column mid-visible
AOT, and the Mixing Group.

Five aerosol air mass "Mixing Groups," and thirteen sub-groups, were
identified from a cluster analysis of the entire database. Each Mixing
Group contains the four most abundant component particles in the column
for climatologically common aerosol air masses, and each sub-group
identifies the dominant particles within the Mixing Group.

The MISR "Clim-Likely" data are available as individual monthly 1 x 1
boxes or as global monthly files and are available from a dedicated ASDC
web page:
http://eosweb.larc.nasa.gov/cgi-bin/misr_tools/clim_likely.cgi

and are also accessible under "Special Products" on the ASDC MISR Data
table:
http://eosweb.larc.nasa.gov/PRODOCS/misr/table_misr.html

An interactive tool allows access to monthly individual 1 x 1 boxes, and
an interface option allows download of global monthly files or the
entire database in ASCII format. If you are a new user to our Langley
Web Ordering Tool, a short registration form will need to be completed.
This information is necessary for statistical purposes.
