Tropospheric Aerosol Climatology based on AeroCom phase I experiments


An average (median) aerosol distribution has been constructed from selected aerosol model simulations, assembled in the scope of the 
<a> href="http://nansen.ipsl.jussieu.fr/AEROCOM/">AeroCom initiative</a>.

The simulations and models are described by  Textor et. al (2006), Kinne et al. (2006) and Schulz et al. (2006) (all appeared in Atmospheric Chemistry and Physics). 


The simulations represent meteorological conditions and emissions from the year 2000.

The median aerosol fields  (1x1 degree) are available for total aerosol, sea salt, dust, black carbon, 
particulate organic matter and sulphate. Depending on the variable and the frequency (daily or monthly) 
different models have been used to compute the local median value from different simulations. 

The global attribute in the netCDF file contains more information of the models used for a given field.
