[ncl-talk] skewt_8.ncl sample input file

[Guido Cioni]

Hey Mike,
the format of the input data file (in this case an ASCI file) needed can vary a lot, but it must contain the variables required by the skewT_PlotData function, i.e. air pressure, air temperature, air dew point temperature, height, wind speed and wind direction. It doesn’t matter how the file looks like, you just need to read the variable, do the necessary conversion and then provide them to the function. 
For this reason, you don’t need all the columns present in the file that you are mentioning…

I’m attaching an example script (really simple) and the datafile used to plot a skew t diagram, hope that helps. I’ve taken the data from the Wyoming university website, but as you can see in the script most of the columns are not even used.
