Re: EMITIMES data
Hi, There is no consensus solution for wildfire emissions, but you can utilize some of these data sets. For wildfire detection location, many satellite based products are available such as HMS or MODIS to name two. https://www.ospo.noaa.gov/Products/land/hms.html https://firms.modaps.eosdis.nasa.gov...

Re: FMDV simulation
Hi,
Could you please elaborate what the FMDV simulation is?

Re: working folder not updating
Please, set the file sorting method by "Date modified" (For PC), then you can see updated files real time. If you like to see the content of HYSPLIT outputs, drop it to any editor (notepad for PC), you can see the ASCII part of the file. TDUMP files are in ASCII format, so you can see its content di...

Re: Calculate meteorological variables (precipitation etc.) from Clusters
Personally, I'm using IDL (Interactive Data Language), but Python might be the most popular solution. Matlab or R will work too.

Re: Expected Coordinate system for shapefille background. (10.2)
Default datum for shapefile output is GRS1980. See *.prj file for detailed information (Tutorial 10.5).
Since WGS84 is very similar to GRS1980, I don't expect any trouble to use it. However, please use proper datum transformation using GIS software if you need a high level accuracy.

Re: Calculate meteorological variables (precipitation etc.) from Clusters
Unfortunately, my answer was incorrect. trajmean does not process additional variables. At this moment, you better conduct averaging separately, using other programing language. Using Exel seems to be too troublesome. Sorry for the confusion.

Re: Veryfing message file
Theoretically, all dispersion simulations are different because they involve random number generation by machine. Not sure 10% deviation is common, but the results surely can differ depending on machines (and met data, modeling configurations etc.).

Re: Clustering backwards trajectories
Hi,
Time steps in clustering specifies how many endpoints lines you like to use in clustering calculation (always positive). It is different from the time step in trajectory runs where negative time step indicates the backward simulation.

Re: Calculate meteorological variables (precipitation etc.) from Clusters
Carlo, After cluster analysis, you can find "TRAJ.INP.C*_3" (if ncluster=3) file that includes the list of traj files for specific cluster. You can use its time stamps to separate each cluster case. If you have included specific met. variables in tdump files, "C*mean.tdump" will automatically merges...
