Long simulation time. Wrong configurations?

Dear all, I am doing a very simple concentration simulation with Hysplit. I have constant emissions from a single point source and the simulation duration is a week. I am driving the simulation using the HRRR data. I am generating min-by-min simulated concentrations at roughly 100 m x 100 m grid cel...

How does hysplit do spatial and temporal interpolation?

I'd like to get simulated concentration at one-minute resolution and 100m x 100m spatial resolution. My input meteorological data is HRRR, which is hourly and 3km data. I can specify the grid spacing to be 0.01 degree (roughly 100 m) and sampling interval to 1 min in my Hysplit Setup. But I want to ...

Test case for benchmarking MPI run

We are trying to run "hycm_std" on our platform with 32 nodes. However, we notice that the simulation time is same or even slower than "hycs_std". Is there any test case that we could test our MPI run and benchmark the simulation time? Just try to make sure there is nothing wrong with our setting. I...

How Hysplit treats emission rate and emission duration hour?

The same question has been posted under "Hysplit Linux" session but I thought this is more a general question so move here... I am confused by the way that Hysplit treats the emission rate and the emission duration. For example, I have two emission scenario. For the first emission scenario, I have a...

How Hysplit treats emission rate and emission duration hour?

I am confused by the way that Hysplit treats the emission rate and the emission duration. For example, I have two emission scenario. For the first emission scenario, I have a constant emission rate at 100 kg/hr and the emission duration is set to one hour. For the second emission scenario, I still h...
