使用xarray.open_mddataset() 将多个 GRIB 文件合并到一个单一的 dataset 使用dask 处理大于内存的数据集 使用dask.distributed 进行分布式处理 后续会研究如何使用这些特性。 另外cfgrib 还支持写入 GRIB 文件等特性。 参考 ecmwf/cfgrib https://github.com/ecmwf/cfgrib Using cfgrib to load GRIB data into an ...
3.读取GRIB文件:使用cfgrib库的`open_dataset()`函数打开GRIB文件并返回一个对象。例如: ```python dataset = _dataset('path/to/grib/') ``` 4.访问数据:通过对象的变量属性,您可以访问GRIB文件中的数据。例如,假设GRIB文件中包含一个名为'temperature'的变量,您可以使用以下代码访问该变量的数据: ```python...

An upstream change to xarray's validate_attrs function has broken canonical_dataset_to_grib. This change has not been released yet but will in the coming days. See pydata/xarray#9407 for more details. What are the steps to reproduce the bug? The traceback is below: def canonical_dataset_...
I'm trying to open ERA5 pressure level data inside a grib-file downloaded from the CDS (see the bottom of the post for the download-command). I'm trying to open the data at different time-indices like this, which works fine for any value...
Due to the fact that the NetCDF data model is much more free and extensible than the GRIB one, it is not possible to write a generic xarray.Dataset to a GRIB file. The aim for cfgrib is to implement write support for a subset of carefull...

Hi all, I have data on GRIB2 format file and I want to convert them to netCDF format. The original dataset (confirmed by using pygrib package) has 12 messages: 6 different isobaric levels each with 2 variables (average and maximum) but w...
