• Summary
• In namelist.3dvar, using length_scaling0.5, the
  RMS and BIAS of observation data will be better
  than using length_scaling1 .
• I have no idea what is the best choice of
  cv3, so I just change the cv5s
  length_scaling0.5 1 to compare their
  result .
• After using len_scale0.5, we can see at initial
  time, most of observation datas RMS decrease.
