Graphics: NCL - Example

wrf_dbz1.ncl ; wrf_dbz2.ncl

Example script to calculate and plot dBZ.

In this script note:

1. The default wrf_user_getvar(file,"mdbz",time) and wrf_user_getvar(file,"dbz",time) (as in wrf_dbz1.ncl),
   will use constant intercept parameters (as in early Reisner-2), with values of 8x10^6, 2x10^7, and 4x10^6 m^-4,
   for rain, snow, and graupel, respectively, during calculations.
2. In wrf_dbz2.ncl, we use wrf_user_getvar(file,"(/mdbz","1","1"/),time) and wrf_user_getvar(file,(/"dbz","1","1"/),time)
   Here Both dbz and mdbz will be calculated using intercept parameters for rain, snow, and graupel, which are consistent with
   Thompson, Rasmussen, and Manning (2004, Monthly Weather Review, Vol. 132, No. 2, pp. 519-542.)
       First "1" in wrf_user_getvar
   Frozen particles that are at a temperature above freezing will be assumed to scatter as a liquid particle.
       Second "1" in wrf_user_getvar
