Hi Tracy,

The skewty() function is looking for a variable type of float. Your data is
double.

You can use tofloat() to change them:

  p = tofloat(f->air_pressure) ;hPa
  t = tofloat(f->air_temperature) ;C
  td = tofloat(f->dew_point_temperature) ;C
  z = tofloat(f->altitude) ;m

Hope that helps,

Phillip
