Dissipation rate of turbulent kinetic energy (TKE): Direct numerical simulation (DNS) and atmospheric data

- 'DNS by Mortikov.zip' contains DNS data of stably stratified Couette flow in terms of averaged profiles of different dimensionless parameters for different Reynolds and Richardson numbers performed by E.Mortikov

  The variables are:
  "z" - distance from the bottom wall
  "z+" - wall coordinate
  "z'/L" - dimensionless height as stratification parameter
  "Ri_flux" - flux Richardson number
  "TKE_dissip*z'/tau^(3/2)" - dimensionless dissipation rate of turbulent kinetic energy
  "TPE/TKE" - turbulent potential energy to turbulent kinetic energy ratio or energy Richardson number

- 'DNS by Druzhinin.zip' contains DNS data of stably stratified Couette flow in terms of averaged profiles of different dimensionless parameters for different Reynolds and Richardson numbers performed by O.Druzhinin

  The variables are the same as in 'DNS by Mortikov.zip'.

- Atmospheric data.zip contains atmospheric data from the following sources: research observatory Tiksi in eastern Siberia near the Arctic Ocean coast, offshore oceanographic platform in the Black Sea; and acoustic soundings over arid steppe in the Republic of Kalmykia in Southern Russia
  
  The variables are:
  "z/L" - dimensionless height as stratification parameter
  "Ri_flux" - flux Richardson number
  "TKE_dissip1*z'/tau^(3/2)" - dimensionless dissipation rate of turbulent kinetic energy retrieved via the Kolmogorov -5/3 power law from measured spectra of TKE in the inertial subrange
  "TKE_dissip2*z'/tau^(3/2)" - dimensionless dissipation rate of turbulent kinetic energy retrieved via the steady-state TKE budget 
  "TPE/TKE" - turbulent potential energy to turbulent kinetic energy ratio or energy Richardson number
