Greetings! So here's some example code downloading a single sounding for a particular site (OUN in this case) for one time (01.01.2016): from datetime import datetime from siphon.simplewebservice.wyoming import WyomingUpperAir station = 'OUN' dt = datetime(2016, 1, 1, 12) df = WyomingUpperAir.request_data(dt, station) print(df['pressure'], df['temperature'], df['dewpoint'], df['pw']) This gets pressure, temperature, dewpoint (that's what's provided for a humidity measurement), and precipitable water (pw). If you need it for that many dates, you'll need to make many individual requests. If you go to their web interface: http://weather.uwyo.edu/upperair/sounding.html You can request multiple days for a single site. > Hello, I am doing my doctorate in the field of remote sensing at Atatürk > University.
