    A local library has the *1976* US Standard Atmosphere publication; I've
    even checked it out a couple times. Can't remember if it had temperature
    profiles for different latitudes. I have to visit that library by the
    30th, and at that time I will look.
    
    Maybe you would like to see some actual temperature profiles. Try
    putting "upper air observations", "upper air soundings", "radiosode",
    "rawinsode" etc. in a search engine. You'll get hits like this:

    Here's another site. Their last 10 balloon soundings are online. The
    "airfield sensor data" link shows the current surface conditions,
    including air refractivity. The listed value seems to be multiplied by 1
    million.
