你是怎么运行的run.met2mng.csh这个命令的？
能不能看一下你的参数设置？
谢谢

修改了参数值之后，报错，能帮忙看一下吗？

学习一下 我也要用megan 我想问一下楼主我的wrfchem模拟不出臭氧怎么办  我的PM2.5和NO都有 但NO2和臭氧没有结果 可以加一下楼主的qq或微信好友吗

不好意思，我之前尝试过学习Megan，还是没能搞懂。所以也没办法解决你的问题

楼主 你好，我在运行MEGAN的时候，到这一步提示：
j2g: Command not found.
j2g: Command not found.
j2g: Command not found.
j2g: Command not found.
j2g: Command not found.
j2g: Command not found.
/usr/local/MEGAN31_Calc_Code_191022/src/met2mgn.rad45: error while loading shared libraries: libpgmp.so: cannot open shared object file: No such file or directory
j

我看了MEGANv3.1下，j2g这个命令换成了yj2ymd
不过运行的时候也提示yj2ymd找不到。我想问一下楼主这一步是怎么设置的？恳请指教。

马百兵

为什么我在运行./run.met2mgn.v3.csh对MCIP输出变量处理之后的输出结果变量名和实际变量不符？

您好，我用MEGANv3.1也遇到了一样的问题，请问您最后解决了么？跪求

仔细看一下脚本，其实用日期函数替代就可以了，开发者开发环境中有他自己常用的命令或者自己写的脚本

尼亚

yj2ymd这些函数其实并不需要，你整个脚本弄懂后，会觉得还不如自己写个，可能比他们写的用的顺手

楼主您好，我最近也在学wrfchem，用到megan做生物排放源，能加您请教吗？我的qq739264380
