I want to calculate the total deposited mass in a month. I have output the cdump file containing the level 0 data to txt file using con2asc.exe(con2asc.exe -s -d). I have then multiplied each grid point data with the grid resolution. Is this the correct procedure? The problem I am having is, with th...

It indeed an insightful reading. Thank you for the explaining it descriptively. It cleared up my doubts.

I have some confusion in the deposition. So when we set the pollutant as a particle by assigning the diameter, density, etc; then aren't these properties assigned to the particles we are releasing? i.e the particles defined in the CONTROL file are different from the particles being released? In that...

Thank you for the clarification. I have release rate of ~60000 g/hr from a city area. I calculated the particle number as: x*density*volume of 1 particle = release rate = 60000 , where x denotes the no. of particles. a)So is the NUMPAR an assumed number and not the actual no. of particles being rele...

I am trying to run a particle dispersion. Particle released per cycle ~ 1.97E+21. I have only one source. However when I set this number in NUMPAR and then the MAXPAR accordingly, the model just stops with an error sound with no further calculation. Model started ... HYSPLIT4 - Initialization Last C...

Thank you. It worked.

I get error messages while checking the met file in all the sub menus( Meteorology-> Display Data->Check File/Contour Map/Text Profile/Grid Domain) I am using 0.25 degree GFS data. Even though trajectory/ dispersion runs works properly. Error message: could not read "{E:/HYSPLIT METEROLOGY}/20160513...

Hello. I want to show the dispersion of particulate matter considering the city as area source. How should i set this in the model ? Is there an option? Also, is there any difference between dispersion with area and point sources?
