WRF SOLAR模式可以利用卫星资料的气溶胶AOD550数据,让辐射数据更准确。
(一) WPS中加入AOD 550 数据成功
从MODIS网站下载了MOD08 M3的数据,将里面的AOD 550nm的数据加到了GEOG中,在WPS这步已经成功生成了加入AOD 550数据的met_em文件:
$ ncdump -v AOD5502D12M met_em.d01.2017-01-01_00\:00\:00.nc
……
float AOD5502D12M(Time, south_north, west_east) ;
AOD5502D12M:FieldType = 104 ;
AOD5502D12M:MemoryOrder = "XY " ;
AOD5502D12M:units = "NoUnits" ;
AOD5502D12M:description = "Aerosol Optical Depth Land Ocean Mean" ;
AOD5502D12M:stagger = "M" ;
AOD5502D12M:sr_x = 1 ;
AOD5502D12M:sr_y = 1 ;
……
data:
AOD5502D12M =

……
以上是WPS生成的met_em文件,查看后发现AOD550的数据确实已经加入。
(二)WRF这步,real.exe生成的wrfinput文件中AOD 550数据全部是0(没成功)
修改namelist.wrf
……
&physics
mp_physics = 28, 3, 3,
ra_lw_physics = 4, 1, 1,
ra_sw_physics = 4, 1, 1,
radt = 10, 30, 30,
sf_sfclay_physics = 2, 1, 1,
sf_surface_physics = 2, 2, 2,
bl_pbl_physics = 2, 1, 1,
bldt = 0, 0, 0,
cu_physics = 5, 1, 0,
cudt = 0, 5, 5,
isfflx = 1,
ifsnow = 1,
icloud = 1,
surface_input_source = 1,
num_soil_layers = 4,
sf_urban_physics = 0, 0, 0,
maxiens =1,
maxens =3,
maxens2 =3,
maxens3 =16,
ensdim =144,
aer_opt =2,
alevsiz =12,
no_src_types =1,
aer_aod550_opt =2,
aer_angexp_opt =2,
aer_ssa_opt =2,
aer_asy_opt =1,
aer_asy_val =0.9,
aer_type =1,
swint_opt =1,
use_aero_icbc = .true.,
use_aero_icbc_clim = .false.,
shcu_physics =2,
/
标红部分是根据手册修改的,但是没有什么用,修改以后,哪怕是将aer_aod550_opt = 1, aer_aod550_val = 0.12,生成的wrfinput文件中,AOD数据也全部是0。
(三) 求助各位大神,有谁知道这个问题吗?或者有谁将气溶胶数据加入到WRF模式中过,希望能够得到指点,或者分享一下经验,如果能帮忙解决问题,必有重谢!请各位大神不吝赐教!
