[Suggestion] Use METAR for current weather information?

[Mrnofish]

I've been having problems with current weather information being incorrect.

As a location, I've set the closest International Airport which is a known good source for temperature, humidity, wind data that has lined up well with values measured on-site for a number of years.

Unfortunately, it seems the data source Rain is using (Open Meteo, I believe?) is not using actual airport data, and there are multiple instances in which the values reported deviate significantly from the ones measured, to the point of being actively misleading when the data is used to make informed decisions, typically the temperature is way off (5+ Celsius) and the RH deviation has been up to 20%.

As airports publish weather data in the standardized METAR/TAF format, I wonder if it would be possible to have the app offer the option of using that source instead.

The app wouldn't need to decode the full METAR string, it would be plenty OK for me if only temperature and relative humidity were sourced that way, though I assume others might be interested in accurate wind speed and direction information as well.

As a reference, airport weather information is reported by a variety of specialist sites, among which Weather Underground, and aviation-oriented websites, such as Metar-taf.com.
