 +In the first line it has the header that specifies the content of the following lines.
 +<code>
 +var,var_cmaq,filename,factor,unit,timeint_stat
 +</code>
 +  * var -> Name of the output variable following the conventions.
 +  * var_cmaq -> Variable or List of variables of the CMAQ file to reduce.
 +  * filename -> CMAQ file to reduce.
 +  * factor -> Conversion factor to store the value in the correct units.
 +  * unit -> Units to save the outputs.
 +  * timeint_stat -> Type (or list of types) of the reduceds to do. the Reduced types will be explained in the REDUCED TYPES SECTION.

 +===== Reduced types =====
 +All the output types are saved following the NetCDF conventions with the lat lon localization and the datetime.
 +==== 1h ====
 +This output type is directly the hourly values.
 +
 +The output type will have the same time steps of the input.
 +==== 8h_max ====
 +That's the most complex reduced type.
 +
 +The result is one value for each cell and each day.
 +This result is the maximum daily 8 hour mean.

 +Maximum daily eight-hour mean: the maximum daily eight-hour mean concentration shall be selected by examining eight-hour running averages, calculated from hourly data and updated each hour. Each eight -hour average so calculated shall be assigned to the day on which it ends. i.e. the first calculation period for any one day will be the period from 17:00 on the previous day to 01:00 on that day; the last calculation  period for any one day will be the period from 16:00 to 24:00 on the day.
 +
 +==== day_mean ====
