| Zusammenfassung |
We present results of in situ measurements of neutral temperature during the
ECOMA/MASS rocket campaign. We present and compare results of turbulence
measurements conducted simultaneously by both in situ and doppler radar
techniques. We show that the derived values of the turbulence energy
dissipation rates are similar on average. We also find a region with a near
adiabatic lapse rate with turbulence detected at the upper and lower edge. We
note that it is consistent with expectation for a Kelvin-Helmholtz
instability.
We also present an estimate of the Schmidt numbers, Sc, for the charged
aerosols that utilizes in situ measured small-scale density fluctuations of
charged aerosols and both in situ and radar turbulence measurements. The
derived Schmidt numbers fall within the range between 100 and 4500. This
result agrees with previous estimates based on multi-frequency observations
of PMSE (Rapp et al., 2008) and also with estimates of microphysical
parameters presented in the companion paper by Rapp et al. (2009). |
