These days I wanted to run the Lagranto model to track water vapor transport path. But I got some trouble in installing an available version of Lagranto model. I attempted to use "conda install -c conda-forge lagranto" to download and install a python version of lagranto. But there is some code error while I import and invoke LagrantoRun module in lagranto. I have contacted with the author of lagranto, Mr. Michael Sprenger, he said the python version was no longer supported and gave me a website for the updated sources of lagranto. Poor me.. I can't enter into the download option of lagranto-ECMWF?? Dose anybody ever entered into this website https://iacweb.ethz.ch/staff/sprenger/lagranto/download.html and download lagranto-ECMWF? I guess it was the linux/unix version of lagranto. Or anybody can send me installation package of linux/unix version of lagranto!! Really appreaciate it!
