Re: HYSPLIT Output MASS matter

I am really appreciate for your kind reply and your advice. As you know, I faced on excced particle number warning for long time. I tried to fix the MAXPAR value, But every time that i set MAXPAR larger than that i used, 'Exceed particle number limit' message keep appear. I think it's because meteor...

Re: HYSPLIT Output MASS matter

Thank you for your kind reply. According to your reply, you said deposition layer indicate accumulated concentration. so i need to use last Output time result to calculate the total amount of mass in the deposition layer. But i got another question about your advice. By running the HYSPLIT model, I ...

Question about HYSPLIT total mass matter

I got 100 kg/m2/gird of HYSPLIT model results. If i want to get a total mass of pollutant in a grid, should i multiply area of grid to concentration value? for example area of grid is 100m^2. Then Does (100m^2) * (100 kg/m^2/grid) = 10000kg/grid a total mass of polutant in a grid? Am i right? please...

HYSPLIT Output MASS matter

Dear HYSPLIT Users I used to running HYSPLIT Model to simulate Nuclear Power Plant accident. I used kg/hr as a unit of emission rate. I attached my default_conc below and i emphasize emission rate with Bold font and under line. 19 07 23 01 1 35.41 126.42 50.0 96 0 10000.0 1 D:/G-CIEM_test/ 0723_5DAY...

Re: Deposition output analysis

Thank you for your kind reply.
According to your reply, if i got 120/m2 as HYSPLIT model result and i want to get a hourly deposition concentration, should i divide 120/m2 with 12hour?

I really need your reply.
Thank you in advanced.

Deposition output analysis

Dear HYSPLIT User and staff. I run HYSPLIT model with 12 hour interval meteorological data. siulation duration is 4days. Model was perfectly run and i got 9 results. here is question. Does each HYSPLIT results means 12 hours accumulated concentration? or does it mean average concentration of each ho...

Grib2 file band change and run hysplit

Dear All I have being used GFS0p25 data from UCAR NCAR web site for running HYSPLIT Model. I used api2arl tool to convert Grib2 data to ARL data which need to running HYSPLIT Model. And There wasn't any error while running HYSPLIT. But recently, I found that Grib2 file's band number have been change...

Re: What should i do to use advanced tab in DOS

Thank you for your reply Ma'am But actually i already checked manual which you posted. In the manual, I couldn't find the command file name or control file name which i have to adjust to change the number of maximum particles. That is why i asked you in the hysplit forum. So, please let me know what...

Re: Question about 'Number of particle and puff'

I have one more question. Like your reply, I set increased MAXPAR value. but 'exceeding puff limit' warning keep appear. I set MAXPAR as 3000000 and NUMPAR as -50. And it spends too much time to run a dispersion model. What should i do to get a results quickly with no 'exceeding puff limit' warning....
