Emission rates in HYSPLIT are input in mass unit /h https://www.ready.noaa.gov/hysplitusersguide/S312.htm The easiest way to do what you want is to convert your emission rate in g/s to ug/h. 3 g/s * 3600 s/h * 1e6 ug/g = 1.08e10 ug/h if you input this as the emission rate, then your output will be ...

conappend is what you want to do this.

It works. Thank you!

Hi everyone. How I can get ug/m3 contour by using HYSPLIT. For instance, a source emission rate is 3 g/s of SO2. How I can configure the HYSPLIT then I can get contour in ug/m3. What I tried only get very very small concentration which is around 1E-08/m3. This value is much lower than what I simulat...

Hi everyone. I made few runs for every month in 2020, and I got 12 cdump file. I want to merge them together in a one file. How I can do that? I notice conadd and conappend both may be working. But I don't which one is the correct method or the most appropriate method. Please help and thanks in adva...

Appreciated Alicec.

Thank you Alicec!

Hi everyone. Is there any way to define the study boundary or domian size such as 100 km radius from the centeral point.

Hi everyone. I have a question based on the emission rate. In the dispersion modeling, can I setup different emission rates for different souces in one run. For example, Source A emission rate is 5 mass/hr, and Source B is 9 mass/hr?

Hi everyone, I'm new here and I'm trying to use the method in this topic to change the legends of requency contours as show in below link. https://hysplitbbs.arl.noaa.gov/viewtopic.php?f=27&t=1311&p=5065&hilit=frequency+contour+plotting#p5065 However, there are some problems that I cannot solve. (1)...

Hi, I'm new here. I can change the legends now, but the unit changed from % to mass/m3. Then I noticed by using the suggested command exec\concplot -itfreq.bin -ofreqplot.ps -jC:/hysplit4/graphics/arlmap -m0 -k1 -v10+20+30+40+50+60+70+80+90+100 will also change the type of the plotting figure from f...
