MEGAN 安装运行小问题记录

helibucks9

最近开始学习MEGAN，编译安装了2.1版本（https://bai.ess.uci.edu/megan/data-and-code/megan21）。在用官网测试数据（https://drive.google.com/file/d/0B53BwxgQlv_3eWNpWE1BcUlQX2s/view?resourcekey=0-1fPkid-E3641ac5kMH9L9w）运行的时候，使用run.txt2ioapi.v210.csh脚本将csv转nc时总给我报错Segmentation fault........看log文件发现是与时间有关的错误。

找了一晚上原因，终于知道了是官网安装包里MEGANv2.10/src/TXT2IOAPI文件夹下的两个.f文件有点小问题，分别是cnvt_lai.F和cnvt_pft.F。要分别把脚本中第160行的CALL NEXTIME（0，ITIME, TSTEP3D）改为CALL NEXTIME( IDATE, ITIME, TSTEP3D )。

具体解释见：https://forum.cmascenter.org/t/issue-with-megan-v2-0/1351/2

另外想请问各位大佬，在MEGAN手册里写到的运行MEGAN2.1的最后一步，将ioapi结果转为CAMx低层排放文件的run.ioapi2uam.csh脚本在哪里能找到啊，提前感谢大家！！！！

好的没事了。还是没找到，自己写了。

楼主，请问这个run.ioapi2uam.csh脚本是必须要有的吗？还是说针对某些研究必须要用？方便交流交流关于这个脚本的问题吗？

楼主，请问这个run.ioapi2uam.csh脚本是必须要有的吗？还是说针对某些研究必须要用？方便交流交流关于这 ...

不是必须的，这个脚本的目的是把MEGAN结果转化为CAMx可以读取的排放文件的格式。如果你后期用CAMx的话就可以用这个脚本转换格式，不用CAMx的话就不用管了

好的，谢谢，我用的CMAQ

太厉害了这个方法！解决了大问题

小白求问楼主MEGAN输入文件MGNMET文件里的MET文件是怎么做出来的呀？

楼主好，我的MEGAN卡在了./make_all_programs.scr编译上，有很多的error，我在*.64bit文件中加了-qopenmp，但是还是会有报错，目前具体报错内容如下：
