LBLRTM (Line-By-Line Radiative Transfer Model) 是精确高效的逐线积分辐射传输模型。源于 Fast Atmospheric Signature Code (FASCODE)。波段从紫外到亚毫米。
LBLRTM输入需要LNFL程序运行结果。太阳光谱需要运行 solar source function 程序得到LBLRTM太阳能输入。
LBLRTM运行的流程框图
第一部分介绍LNFL：
LNFL将一个ASCII文件参数数据库转换为LBLRTM输入的非格式化二进制文件TAPE3。
输入的ASCII文件下载链接https://github.com/AER-RC
运行LNFL

然后运行：
\rm TAPE1 TAPE2 TAPE3 TAPE6 TAPE10
# Set up link to AER line file (e.g. aer_v_3.5) that comes in the AER line parameter database
set line_file = "aer_v_3.7"
# Set up link to LNFL executable
set lnfl_ex = "../../lnfl_v3.2_linux_pgi_sgl"
\rm TAPE5 TAPE1 TAPE3 lnfl
#ln -s $line_file TAPE1
ln -s TAPE5_ex TAPE5
ln -s $lnfl_ex lnfl
./lnfl $line_file
\mv TAPE3 TAPE3_$line_file
\mv TAPE6 TAPE6_$line_file
\mv TAPE7 TAPE7_$line_file
运行结果TAPE3，TAPE6，TAPE10，TAPE7
