plotting error

[basitkhanNZ]

Hi there, I am a new Bee and trying to plot ecmwf forecast chart using the notebook script for 850 Temp and 500 Geopotential height, but getting the following error. I already downloaded the api key and code runs fine until it comes to the plotting functions where i get the following errors,

Any help in fixing the error will be greatly appreciated.

Cheers, Basit

Hi Basit, The libraries used for data processing and visualisation in these notebooks were experimental and will need to be updated. I expect to update the notebooks to use the new libraries during the summer this year. They will be using the new earthkit-maps library. You can also have a look at our Metview library for plotting the grib data. Sorry for the inconvenience.

Dear Milanavuckoiv,

Many thanks for the quick response. The information was quite helpful, specially about the metview application. I installed it on my laptop and watched a few webinars on its application and capabilities by ECMWF colleagues. Its amazing utility. The documentation says metview it can also handle netCDF data, i wonder if it has the same capabilities and convenience for netCDF data as it has for Grib data?

Thanks again and I look forward to the updated scripts.

best wishes, Basit

Dear Basit, The capabilities of Metview are indeed not the same for NetCDF data as for GRIB data. I can recommend xarray for the NetCDF data. Best regards, Milana
