Sounding Display


-SHARPpy Documentation-

Unless otherwise noted; inqueries about the sounding display can be resolved by referencing the SHARPpy documentation found here

-Local Modifications-

Wind bars and Hodograph segments are color-coded base on height AGL in KM from 0-1, 1-3, 3-6, 6-9, and >9KM in magenta, red, green, yellow, and cyan respectively.
