${levels}

To diagnose the error you encountered, could you provide us with more details? - Version of HYSPLIT - Version of your Windows operating system - Which meteorology file were you downloading...

The file_merge program included in your HYSPLIT installation may be used to combine two ARL-formatted meteorological files. The program is located in the exec directory where HYSPLIT is installed, for example, C:\hysplit\exec. Please refer to https://www.ready.noaa.gov/hysplitusersguide/util.htm#fil...
