最后一段
OPTIONAL: Turn on the aerosol optical properties (e.g., aer_op_opt, opt_pars_out) to obtain the extinction coefficient in the wrfout file and rerun the simulation. Examine the EXTCOEF fields. Are these fields non-zero? Do the higher values correlate with locations of higher aerosol concentration? The vertical sum of each EXTCOEF field multiplied by the layer depth is the computed Aerosol Optical Depth (AOD) at a particular wavelength.
dz(1) = z_at_w(2) - z_at_w(1)
dz(2) = z_at_w(3) - z_at_w(2)
...
dz(e_vert-1) = z_at_w(e_vert) - z_at_w(e_vert-1)
AOD = SUM[EXTCOEF55(1)*dz(1) + EXTCOEF55(2)*dz(2) + ... + EXTCOEF55(n)*dz(e_vert-1)] 现在把opt_pars_out改成了1。不知道对不对。。。尝试中。。。
结果是可以的。能算出来了。 |
