Re: Vertical Mass Distribution

alicec, Here is a link to the cdump and pardump outputs. https://ftp.ornl.gov/filedownload?ftp=e;dir=uP438gRlTlPO The equation I use to calculate the area of the grid cell is dLat * dLon * COS(lat1 / 57.2957795130823) * 111198.41730306273 ** 2. Where dLat and dLon are the distance for a grid cell in...

Re: Vertical Mass Distribution

I am having a similar issue where if I integration the average mass concentration for the first sample time I get more mass then I initialized with. I am using PARINIT to start HYSPLIT. The PARINIT file contains 1.03124e+09 grams of mass. The PARDUMP coordinates this with the same mass at startup an...

PARDUMP zero lat/lon?

I am currently processing PARDUMP files to generate visualizations and I'm seeing a number of particle positions that have zero lat/long.

Is this expected behavior?

Should I throw away these zero locations? Is there another way to handle these?

Re: PARINIT vs. EMITIMES

I have resolved my issue.
It was two fold.
The first was big endian vs little endian.
The second was I misunderstood the number of pollutants on each particle.

I have this working now.

PARINIT vs. EMITIMES

I am currently running multiple pollutants with several locations per pollutant via CONTROL+EMITIMES. My typical run contains 100 pollutants with ~17 emissions for each pollutant. Each location has a different emission, so I'm required to have 1700 locations for the EMITIMES format. I need a vertica...
