Xarray (from grib file) to dataset

Asked 2021-Jun-16 at 02:36

I have a grib file containing monthly precipitation and temperature from 1989 to 2018 (extracted from ERA5-Land).

I need to have those data in a dataset format with 6 column : longitude, latitude, ID of the cell/point in the grib file, date, temperature and precipitation.

I first imported the file using cfgrib. Here is what contains the xdata list after importation:

Can the crgrib engine handle reading remote files? It doesn't look like it according to Martin Durant's comment (https://github.com/ecmwf/cfgrib/issues/198#issuecomment-772852412)

There is a smallish grib file hosted on s3: https://mf-nwp-models.s3.amazonaws.com/index.html#arpege-world/v2/2021-02-16/00/UGRD/10m/ (note don't click on a file as it'll download).

How to encapsulate an imported module into a method for multithreading in python?

Asked 2021-Feb-10 at 07:57

I'm new in python and I have a concurrent problem when using internal functions of importing libraries. The problem is that my code calculates different kinds of variables and in the last process they are saved into different files. But I have the same problem when reading and writing.

This is an example code that works because is linear:

As I'm new in python I was unaware of the different kinds of threads that we can create, so in my example above, I was using the ThreadPool that can be locked by the GIL (Global Interpreter Lock), so to avoid it there is another kind of threads we can use, here an example:

ECCODES ERROR when opening .GRIB file in Spyder

Asked 2020-Oct-27 at 09:45

I have accessed Anaconda Prompt for the environment that I will be working.

Once there, I have changed the directory to the place where I have the grib files that I will be working with, in order to install cfgrib, I have used the following command:

conda install -c conda-forge cfgrib

As the Python module depends on ECMWF ecCodes binary library, in the same Anaconda Prompt, I ran the following command:

conda install -c conda-forge eccodes

Then, opened the file in Spyder, and tried to run this simple script:

It appears the solution (sorta) to this was to simply use a different projection than the LambertConformal projection I was using originally. Not exactly sure what was wrong so this is only a circumvention to the original problem.
