About
The dissipating atmospheric waves can cause highly-varying intense turbulent layers surrounding space capsules/shuttles while reentering the atmosphere from space with high mach speeds in the height region of 70-100 km. High time (few minutes) and spatial (few kilometers in horizontal and fraction of kilometers in the vertical) resolution measurement of wind velocities in this height region is a must to
determine with less errors the atmospheric eddy dissipation rates, which is possible with medium (2-3 MHz) frequency Doppler radars.
