Re: How to calculate potential vorticity (PV) along the trajectory
You can calculate PV array from the existing variables and than interpolate to the end point positions of the trajectories. There is a MPV example online (http://meteothink.org/examples/meteoinfolab/meteo_analysis/moisture_potential_vorticity.html). Replace pseudo-equivalent potential temperature to...

Re: Web domain changed to meteothink.org
Glenn,
Thanks for your quickly response on it! Also TrajStat links need to be updated on the READY web site.

Read trajectory data as 2D array
The trajectory endpoint data file can be read as 2D arrays following netCDF data model from MeteoInfo version 1.6. The dimensions are 'trajectory' (trajectory number) and 'obs' (endpoint number of one trajectory). Detail and example can be found here: http://www.meteothink.org/examples/meteoinfolab/...

Web domain changed to meteothink.org
The previous meteothinker.com domain is no appropriate for MeteoInfo software due to its open source nature, and the previous web hosting was not stable from several weeks ago. So I moved the web site to GoDaddy with a new domain of meteothink.org (http://meteothink.org/). Please revise the web link...

Re: ASCII to cdump file
You may try MeteoInfoLab script to get the max value and location from cdump file, and plot it on map. #Read data array from HYSPLIT concentration output data fn = r'D:\Working\MIScript\JapanNuclear\cdump15' f = addfile_hyconc(fn) data = f['C137'][:,0,:,:] # 3 dimension array - time, lat, lon #Get t...

Re: mixing height data
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 .

Re: Connverting tgs file to shape file
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).

TrajStat 1.4.5 was released
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...

Re: Clarification on meteorological data
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...
