High-resolution temperature profiles measured with stratospheric balloons near the Andes Mountains

A spectral analysis of two balloon soundings of temperature performed in the troposphere and lower stratosphere over the Andes Mountains in Argentina with a vertical resolution of 10 m has been performed. The first and second soundings, launched at the same location, were performed during unusually...
