Kevin, I wrote the metar2nc decoder over 5 years ago, can't say that I know the details about variables now. But here's URL to the metar handbook: http://www.nws.noaa.gov/oso/oso1/oso12/fmh1/fmh1toc.htm Look at section 9 for your answers. Also if you find any discrepanies between the handbook and the code, I would like to know. Thanks, Robb...
