Due to the current gap in continued funding from the U.S. National Science Foundation (NSF), the NSF Unidata Program Center has temporarily paused most operations. See NSF Unidata Pause in Most Operations for details.

MetPy 0.12.0 Released

MetPy 0.12.0 has been released:

  • Added support for Python 3.8, dropped support for Python 2.7
  • precipitable_water now issues a FutureWarning due to an impending change to its function signature in 1.0--this will change the signature to precipitable_water(pressure, dewpt, *, bottom=None, top=None) for better consistency with the rest of the library. To avoid this warning, import the function with from metpy.future import precipitable_water
  • storm_relative_helicity now issues a FutureWarning due to an impending change to its function signature in 1.0--this will change the signature to storm_relative_helicity(heights, u, v, depth, *, bottom, storm_u, storm_v) for better consistency with the rest of the library. To avoid this warning, import the function with from metpy.future import storm_relative_helicity
  • dewpoint_rh has been deprecated in favor of dewpoint_from_relative_humidity, and will be removed in 1.0
  • Removed previously deprecated functions get_wind_components, get_wind_dir, get_wind_speed, interp, interpolate_nans, and log_interp as well as the metpy.gridding sub-package.
  • Added parser for METAR-formatted reports
  • Update NEXRAD Level2File to handle future format changes
  • Added calculation mixed_layer_cape_cin
  • geopotential <-> height calculations modified to use standard gravity
  • Added declarative interface for station plots
  • Added arrows to go with barbs on station plots
  • Compatibility fixes for future versions of Pint
  • Enhancements to xarray coordinate identification
  • Fixed average spacing calculation in interpolation
  • Added 'wide' and 'most_cape' options for LFC/EL
  • Added wx_code_to_numeric for converting text weather codes (e.g. '+SNRA') to corresponding WMO code.
