    I'm wondering if anyone can confirm what the units are in the json file? i.e.: in a message like this:

    {'hex': 'ad1218', 'squawk': '3367', 'flight': 'AAL2892 ', 'lat': 37.518171, 'lon': -122.47069, 'nucp': 7, 'seen_pos': 0.7, 'altitude': 13225, 'vert_rate': 3968, 'track': 179, 'speed': 361, 'category': 'A3', 'mlat': [], 'tisb': [], 'messages': 1946, 'seen': 0.2, 'rssi': -8.1}

    What units are vert_rate, speed, and altitude provided in? Thank you!

    Compare it with the the values in the webinterface for an easy answer.

    Anyhow it's ft, ft/min and knots.
