A bug exists in MeteoInfo for HYSPLIT output concentration data reading. The i, j index of non-zero elements can be read from data record 8, and the i, j index starting from 1 following Fortran language. MeteoInfo was developed using Java with 0 starting array, so the element positions were read inc...

An example for trajectory length calculation script was added in MeteoInfo website: http://meteothink.org/examples/meteoinf ... ength.html .

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...

Great, thanks!

Glenn,

Thanks for your quickly response on it! Also TrajStat links need to be updated on the READY web site.

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/...

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...

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...

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).
