This readme file describes the output for simulations of UFP over California
carried out for 2000-2016.

Note: the data is considered preliminary until the publications describing 
it have been finalized.  

The files under data/soa_v3/hourly_avg describe hourly average concentrations
in the different size fractions.  The NORTHCA4KM results cover the 
northern California domain with 4KM resolution.  The SOUTHCA4KM results cover
the southern California domain with 4KM resolution.  Map projection information
is shown below:

 map_proj = 'lambert',
 ref_lat   =  37.00,
 ref_lon   = -120.50,
 truelat1  =  30.0,
 truelat2  =  60.0,
 stand_lon = -120.50,

The origin of 4km_scb domain is (-33km,-475km), grid dimensions are 102 X 60

The origin of 4km_sjv domain is (-225km, -211km), grid dimensions are 108 X 108.

The file format is binary.  A Fortran program is available at 
http://169.237.114.233/data/soa/programs/read_data.f90 to read the air quality.
An instruction file how_to_read_data.txt describes how to use the program.

The air quality data include gas and PM species.  A complete species list is available
at http://169.237.114.233/data/soa/programs/Species_list.txt
