Hi Ryan!! Thank you very much! Yes, it does help me a lot.. Best regards Gustav On 2021-06-16 14:25, Ryan May wrote:
Greetings! To accomplish something similar to GEMPAK's sfmap, what you're looking is probably MetPy's simplified/declarative plotting interface. This example creates a station model plot using it: https://unidata.github.io/MetPy/latest/examples/plots/surface_declarative.html As far as what data you can use with MetPy, any format that you can read into numpy/pandas/xarray can be used with MetPy. We have been working on solutions to use many of the formats traditionally used for meteorological applications. For instance, the example above uses Pandas to read a CSV file of observations. MetPy also has a METAR parser that can generate a Pandas DataFrame, which could instead be used with that code: https://unidata.github.io/MetPy/latest/tutorials/declarative_tutorial.html#plot-surface-obs This METAR parser should work fine with data downloaded from https://thredds-test.unidata.ucar.edu/thredds/catalog/noaaport/text/metar/catalog.html (considering that it was tested extensively using it). Hope this helps! Ryan On Tue, Jun 8, 2021 at 8:43 AM banco <banco@xxxxxxxxxxxxxx> wrote:Good morning!! I am a Gempak user. And I would like to use Python MetPy environment too. At the beginning, if possible, the aim is to have both softwares working. I would appreciate if someone knows how, in Python environment,: 1) if a file is read (Synop data for instance) in Gempak's scripts, using sfmap, in this way: sfmap << EOF SFPARM = skyc:.4;tmpc;wsym:.7;ALTM;;dwpc;brbk:.8::212 SFFILE = /data/ldm/gempak/surface/20210607_sao.gem ..... How would the equivalent in a Python MetPy environment be? At this url, GEMPAK Comparison Guide, https://unidata.github.io/MetPy/latest/userguide/gempak.html this sfmap's GEMPAK Function (Python/MetPy Equilvalent) has its row empty. 2) On the other hand, in a context of acquiring files data from LDM, what kind of which file format should be used to read them in a Pyhon Metpy environment? ** The name and extension of the file is different? Does this mean one has to change LDM configuration? ** Is this different than reading from THREDDS Data Server? Isn't it?https://thredds-test.unidata.ucar.edu/thredds/catalog/noaaport/text/metar/catalog.htmlI have been looking for files or videos on YouTube on the subject but by the time being I cannot find these subjects. Is it somewhere on this website(about userguide)? https://unidata.github.io/MetPy/latest/userguide/index.html Any help is welcome: any link, website's page, Unidata's video, etc. Thank you very much in advance.
