Hi.
So I wanted to add a new topic, but the site says I'm not allowed to do that.
Help?
Thanks

Same here. How I can plot a sub-selected variable from a GRIB file that is comprised of many other variables ?

Hi Songhan,
(I can't create a new topic either)
I don't have a Magics answer for you but will make a suggestion using Metview:
I use Metview macros in general for plotting. Most GRIB I plot are in files with more than one GRIB record. I use the following macro code to pick the GRIB record (parameter-number/level-type/level) I want to plot. It might be possible to translate this for use in Magics python/magml/...

Hi Songhan, and thanks for your comment Eoin!
Again, a reply that uses Metview - depending on how similar your GRIB files are to the ones archived at ECMWF, Metview's Grib Filter module can give an easy way to do it:
This does not work with all non-ECMWF data though.
Outside of Metview, perhaps the GRIB_API tool grib_filter can do what you want, i.e. to filter out just the fields you want to plot.
Best regards,
Iain

I am afraid that the creation of topics is limited to people with write access to the wiki. But do drop an email to software.support@ecmwf.int and we can either create the topic for you or to answer the question directly
