Dear all,

I want to set up a concentration run in Hysplit4 with temporal varied emissions at a single emission source, using the EMITIMES file with 99 "Emission Cycle Data Records". The content in my EMITIMES file is someting like:

YYYY MM DD HH DURATION(hhhh) #RECORDS
YYYY MM DD HH M DURATION(hhmm) LAT LON HGT(m) RATE(/h) AREA(m2) HEAT(w)
1995 10 16 00 9999 99
1995 10 16 00 00 0300 40.243 -100.406 10.0 3.0 0.0 0.0
1995 10 16 03 00 0300 40.243 -100.406 10.0 3.0 0.0 0.0
... (totally 99 records)

The file format is similar to that for the SMOKE case in:
http://www.meteozone.com/tutorial/html/cust_smoke.html

For the corresponding CONTROL file, if I set ONE starting location, the model cannot run. If I set 99 starting locations with the same lat, long, height for all locations, the model runs successfully. Did I properly set up the model? Please suggest otherwise.

Many thanks.

Your configuration is correct. However, in order to avoid repeating 99 times the location in the CONTROL file you can use one header per record as follows:


YYYY MM DD HH DURATION(hhhh) #RECORDS
YYYY MM DD HH M DURATION(hhmm) LAT LON HGT(m) RATE(/h) AREA(m2) HEAT(w)
1995 10 16 00 0300 1
1995 10 16 00 00 0300 40.243 -100.406 10.0 3.0 0.0 0.0
1995 10 16 00 0300 1
1995 10 16 00 00 0300 40.243 -100.406 10.0 3.0 0.0 0.0
1995 10 16 00 0300 1
1995 10 16 00 00 0300 40.243 -100.406 10.0 3.0 0.0 0.0
etc....
