LIMITATION: There is no support for forecasts of any kind.LIMITATION: There is no support for turning objects from the model back into text forms like METAR or XML. That is, the class library supports decoding, but not encoding.
LIMITATION: Various aspects of some readings and measurements are not supported. For example, neither variable visibility nor runway visual-range are supported by the Visibility class.
LIMITATION: Support for US METAR fields is somewhat better than support for non-US METAR formats. This is mainly because I couldn't find much reference material on the web that described the non-US formats in sufficient detail. Sometimes I did find references, or could guess what the meaning was by reading observations. Code based on actual references is more reliable than code based on my guesses.LIMITATION: Not all US METAR fields are supported. For example, runway visual range isn't supported. Remark elements also tend to be less supported than body elements.
LIMITATION: The decoding of present-weather and recent-weather phenomena by the DoWeatherPhenom class is a bit lax. In particular, unrecognized symbols that happen to be mixed in with recognizable symbols don't cause errors. Instead, the recognizable symbols are decoded as if there were no unrecognized parts. This is not necessarily a good idea.
LIMITATION: All trend-forecast elements in METAR data are unceremoniously ignored. This is basically because there's no support for forecasts of any kind.
