|
Draws pressure in hPa.
|
|
Copy/link file as 'weather_pressure_CODE', like: weather_pressure_LOWW for Austria, Vienna.
|
|
|
|
Get the code by going to https://tgftp.nws.noaa.gov, selecting your
|
|
location, and copying the code from the address bar of your browser; should
|
|
be something like CODE.html.
