ECMWF open data 0p25 grib2 Vtable?

meteoadriatic said:
你好 Kelly，

provided Vtable.ECMWF 遗憾的是它无法像预期的那样使用 grib1 格式。我尝试使用 cnvgrib 将 grib2 转换为 grib1，但它也失败了。

我希望有人已经有了新的 Vtable，但好吧，看起来我需要使用您提到的工具创建新的 Vtable。无论如何，谢谢你。如果我成功了，我稍后会在这里发布有效的解决方案。

您好，您有什么结果吗？

Hi,
Please see Using Newer ECMWF Data, which was just posted. Let me know if this is useful in solving this problem.

Hello, thank you very much for sharing, but I use this method to process the OPER data of IFS in EC, and the Vtable used is Vtable.ECMWF in WRF4.6, but there is such a problem during the operation, is this normal? Attached here is my processing process file.

The ungrib.log you attached looks to be incomplete. There is no error message at the bottom. When you process ungrib.exe, does it run to this point and then just stop, or does it hang and you stop it after a while?

Hello,
Did you test this method successfully? If yes, may I ask:
1) Did you use ECMWF files from ECPDS, here? ECMWF Data Store (ECPDS)
2) Which version of the grib_set tool did you use?

I'm asking, because in my tests, this doesn't work; my ungrib does not recognize soil fields at all... I wrote about this here. Please let me know. Thanks.
 
I use ECMWF IFS oper grid2，/Ungrib.exe executed successfully， but / Metgrid.exe execution failed
At line 111 of file gridinfo_module.f90 (unit = 10, file = 'namelist.wps')
Fortran runtime error: End of file

He didn't stop running here.,There's a paragraph below.,It's when you can't find the corresponding date data.

are you using a subset of the data or downloading the whole globe?

how to use eccodes to separate out grib 2 and grib 1 data first before running ungrib based on ECMWF data. :cry:

Using Newer ECMWF Data

The new EC grib2 data requires an additional step to convert from EC grib2 data to grib2 data WPS supports. The conversion can be done by using the convert command in the ecCodes library which is available from ECMWF. The conversion step follows the following format: grib_set -r -w...

thanks for your reply , it loss soil data, but NCAR researcher said we can use ecCodes to extra it, but I dont know how to do it!
 
这是我的解决办法，已经可以正常运行了，将附件脚本放入下载的ECMWF气象预测文件夹内，我这里下载的是https://data.ecmwf.int/forecasts/20...和wgrib2,这样处理完的数据会生成到脚本对应的目录，你可以自行修改output_dir = '/home/WPS/NEW-ECWMF'，再然后就按照正常的WPS去处理这个数据，关于Vtable.ECMWF我也放在附件里。当运行WRF中的real.exe的时候，需要将namelist.input中的sf_surface_physics 设置为1，然后就可以正常运行了，至于为什么其他地表方案不行，应该是ECMWF的数据有部分缺失。还有就是num_metgrid_levels 设置为14，num_metgrid_soil_levels设置为3，我没有设置为4去试，如果有人试了，可以告诉我结果。

老哥， oper和enfo有啥区别,我准备测试Oper+GFS混合输入WRF

oper是预测数据，enfo好像是比较全的吧，之前以为缺失土壤层数，就拿这个数据试过，后来enfo的数据太大，处理完一个三小时的数据大概是9G，好像WPS运行不了这么大的数据，后面就没折腾了，具体内容，你下载的时候，他那有个.index文件，里面有这个文件包含的所有的东西。
