If you mean to extract PBLH data at a specific location from existing meteorological data (such as GDAS data), you can follow the example here: http://www.meteothinker.com/examples/me ... rp_st.html .

Firstly you should make sure that you have calculated trajectories correctly. Or you may got empty .tgs file so no .shp file can be created. You can learn MeteoInfo and TrajStat from my presentation in 2018 HYSPLIT workshop (http://www.meteothinker.com/docs/introd ... esentation).

Add Check point number button in cluster calculation dialog to check the end point number of each trajectory. Add 3D trajectory chart to explore the trajectories in 3D view. Add Save to grid menu item to save PSCF/CWT data in a Sufer ASCII grid data file, which can be loaded and plot as a contour la...

You can use MeteoInfoMap to explore the ARL data file. Or use MeteoInfoLab script to extract PBLH data at a specific location from GDAS data. An example script: lat = 40.0 lon = 120.5 fn = 'D:/Temp/arl/20140301_gdas0p5' f = addfile(fn) pblh = f['PBLH'][:,str(lat),str(lon)] #Plot plot(pblh, '-bo') yl...

Get a HYSPLIT output concentration data file object using addfile_hyocnc function, and then read 2D array for filled contour plot. Following is an example of cesium-137 simulation during 2011 Fukushima nuclear disaster. fn = r'D:\Working\MIScript\JapanNuclear\cdump15' f = addfile_hyconc(fn) tidx = 5...

You need to set vertical motion method to 4:sigma for this meteorological data.

MeteoInfo 1.4.6 was released with 3-D trajectory plot function (http://www.meteothinker.com/news/meteoinfo_1.4.6.html).

You can create point shape file from HYSPLIT trajectory data file using MeteoInfo. All variable values will be added in attribute table including time stamp and altitude.

Another option is to write MeteoInfoLab script to extract the variable values from meteorological data along trajetory. There is a online example: http://www.meteothinker.com/examples/me ... _data.html .

The 'convert2nc' function can be used to convert many data formats to netCDF, including ARL and HYSPLIT concentration data. MeteoInfo 1.4.3R3 or better version is needed. For ARL data: infn = 'D:/Temp/arl/gdas1.jul09.w5' #Input ARL file outfn = 'D:/Temp/arl/gdas1.jul09.w5.nc' #Output netCDF file con...
