discrete calculation possibility

[ariel.stein]

The simplest way is to set up the hours of emission to 8 hours in the CONTROL file and make 24 hour duration runs for every day.
Below is a sample of such CONTROL file (I highlighted in Bold the 8 hours emission and the 24 hour duration) :
00 00 00 00
1
40.0 -90.0 10.0
24

0.0 0.0 0.0
0.0 0.0 0.0 0.0 0.0
0.0 0.0 0.0
0.0
0.0

You will also have to write a script to make the runs for every day.
