Brent,

thanks for the bug reports, they are indeed problems. the next release
will have the fixes. have you looked at the new metar decoder
metar2nc.new1? the netCDF file is almost CF compliant, it offers
following links to get time series on a station, the performance is better
and it packs a day's worth of data into one file ~40 megs. i would
appreciate your comments. also have you heard that the nws is planning to
change the text format to a bufr format, what do you think about that?
