怎么把多个时间段的grib数据合成一个grib数据集

云大小子

怎么把多个时间段的grib数据合成一个grib数据集 我的grib2数据是一个月一个的，如果要分析年平均情况就不方便，在此急切求解惑。

今天也遇到这个问题，贴出解决方法，供以后遇到的人参考：
创建一个ctl用来包括多个文件（修改第一个时次的ctl文件即可）需要修改的地方：
1 dset那一行，文件名改成 有通配符的格式： dset D:\pgbh00.gdas.198709%d2%h2.grb2
2 tdef那一行， 修改时间总数，时间间隔 ： tdef 120 linear 00Z01sep1987 6hr
3 生成idx索引文件的地方（可选，建议修改）： index D:\pgbh00.gdas.198709.grb2.idx
4 添加选项 “options template”
然后运行命令!gribmap，再在弹出窗口输入刚刚创建的ctl路径，回车，生成idx文件
这就可以用这个ctl读取多个文件了。

批量描述试试？可以翻一下lasg的那本手册啦

artmunich

GrADS中有个option是template，可以由一个ctl描述多个数据文件

但是grads不能直接读取grib2数据啊 ，这个有关系吧。

我刚学grads，我听你一说感觉合适，我试试看看lasg这方面的操作。我还想问你这个ctl描述文件是不是用grid2ctl。exe来生成，用gridctl.exe打开多个grib数据 再操作

grib2ctl用来生成ctl格式的描述文件，gribmap.exe用来生成格式idx的映射文件

两个ctl和两个。idx文件都生成了，然后我自己写一个总的ctl文件把这两个文件包括进去怎么打不开呢 下面是我的ctl文件 哈

哈得来环流

按照你的要求，多个时段的grib文件合成一个grib集后，只用调用一个ctl即可，idx映射文件也只用一个

谢谢，我的问题已经解决
