HYSPLIT Forum: hysplitbbs.arl.noaa.gov

When the model is run, calculation starts and proceeds to end as normal. But in concentration output file, all quantities are "zero".

The differences are:
Total run time
Emission rate
Hours of emission
Sampling interval

About sampling interval, I want to define maximum concentration grid every one hour. I set " 02 01 00 " and I think this is the problem. What Should I do?

I have used HYSPLIT to calculate concentration several times. But this time all output is zero and I can't find the problem.
Would you please give advise to solve it?

I used a high performance computer and it has worked. As you mentioned the problem was the machine to handle the data.
Thanks so much.

I used a system with 26 GB free memory but it is same as past with 6 GB free memory and the full message is:

MGMIN set to MAX for meteorology grid: 360
configuration corrected, continuing ...
calculation started ... please be patient

Thanks for your kindly attention.
I concatenate weekly gdas file of one year and now there are 12 gdas file, every month one file. When I set to run, it is written that calculation started but nothing is happened.

I want to calculate for one year run time, but there is this error:
*ERROR* runset: Numb meteo grids exceed DEFGRID limit
so I increased Sub-grid Size in: Advanced / Configuration Setup / Sub-grid Size and Vertical Coordinate, but the error has exist yet.
please guide me.
thanks so much

Dose HYSPLIT have the ability to do sensitivity analysis on source term? or I should do by repeating calculations?

I have used HYSPLIT for continuous release of source term. I was wondering to know that Is there possible to repeat calculation for some hours daily release of source term discretely? for example 8 hours release in every day for one year.

Thanks for your attention
I found one SETUP.CFG file in hysplit4\examples\configs\volcano folder. Do you mean that I need to change the MAXPAR parameter in this file?
