The z2sig.def file contains the pseudo-altitudes (in km) at which the user wants to set the vertical levels. Note that levels should be unevenly spread, with a higher resolution near the surface in order to capture the rapid variations of variables there. It is recommended to use the altitude levels as set in the z2sig.def file provided in the deftank directory.
Example of z2sig.def file:
8 H: atmospheric scale height (km) (used as a reference only) 0.004 Typical pseudo-altitude (m) for 1st layer (z=H*log(sigma)) 0.017415589434569632 ,, ,, ,, ,, ,, ,, ,, ,, ,, 2nd layer, etc... 0.04197041134830409 0.09573548831202484 0.19905425549248695 0.37769312558816376 0.6610287582071787 1.0796026837077486 1.6625722655258326 2.4354958342473516 3.4187160120951323 4.626429653543951 6.066400344124698 7.740192276155182 9.643775222138789 11.768354425931134 14.10130177147987 17. 20. 23. 26.5 30. 34. 38. 42. 47. 52. 60. 68. 76. 82. 88. 94. 100. 105. 110. 115. 120. 125. 130.
