It's hard to say why you got wrong result without detailed step description. The only suggestion at present is to use newest version of MeteoInfo and TrajStat if you are using old ones.

The website also provide 'Data Format Conversion' option for users to download the data as netcdf data format. Your data file looks like netcdf format with .nc postfix.

Wrong latitude of 63.333 in your figure. Correct one is 63.633.

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...
