1.1.0

This is the first feature release since 1.0.

Highlights

  • Added classes to read a variety of data in GEMPAK-formatted files
  • Added showalter_index calculation
  • Added PlotGeometry to the simplified plotting interface, which makes it easy to plot a variety of geospatial data (e.g. SPC convective outlooks or NHC hurricane wind swaths in geojson format). See this notebook for examples.
  • Significantly improved METAR parser to output both the visibility and remarks part of the reports, as well as better handle more weather codes (like 'FU')
  • Improvements to simplified plotting interface including better notebook tab completion, support for controlling font size, and GEMPAK-like zooming on areas (e.g. '+us')
  • Improved detection of problematic soundings in calculations
  • Dropped support for Python <3.7 and NumPy <1.17
  • Reduced the time it takes to import metpy.io
  • Fixed up a variety of unit issues in calculations

1.0.0

Our first stable API release. Crux of it will be eliminating all deprecated functionality (like dim_order), ironing out the XArray/units integration, and making sure function calls are something we're willing to support for a few years.

API Changes

  • dx/dy and dim_x/dim_y arguments divergence and vorticity are now only passable as keyword arguments
  • Can no longer set values in a DataArray using the unit_array accessor attribute
  • When DataArray instances are passed as inputs, the returned values are almost always also DataArray instances rather than Pint Quantity instances.
  • lat_lon_grid_deltas now takes a pyproj.Geod instance directly rather than keyword arguments for constructing one.
  • Removed dim_order argument--all functions either rely on DataArray metadata or assume data have trailing dimensions as y, x
  • Remove previously deprecated items
    • bounds argument to plot_colormapped
    • tmpk_out argument to isentropic_interpolation
    • dewpoint_rh
    • Viridis colortable
  • Rename many function arguments to be consistent and clear (e.g. potential_temperature instead of thta)
  • Re-order function arguments to (pressure, temperature, moisture) to be consistent with rest of library:
    • relative_humidity_wet_psychrometric
    • psychrometric_vapor_pressure_wet
    • mixing_ratio_from_relative_humidity
    • relative_humidity_from_mixing_ratio
    • relative_humidity_from_specific_humidity
    • dewpoint_from_specific_humidity
    • specific_humidity_from_dewpoint
  • Update signatures for ageostrophic_wind, precipitable_water, and storm_relative_helicity (as warned previously)

Highlights

  • New documentation layout and theme
  • Add 1.0 upgrade guide
  • Update constant values from more robust sources
  • Better support for taking in xarray DataArrays
  • Add capability to limit shading of CIN on SkewT
  • Function to add longitude/latitude to Pandas DataFrame
  • Support for % as a unit abbreviation in a string
  • Support for changing barb size on station plots in simplified plotting interface
  • Fixed up declarative interface docs
  • Support for returning xarray DataArrays instances from calculations when the inputs are also DataArray instances
  • Support for inputs where Pint Quantity instances are stored within DataArray instances
  • Fixes errors when passing masked arrays to various CAPE calculations
  • Support for Albers Equal Area projection
  • Many fixes updates for NEXRAD format support, including direct reading of file objects from the NEXRAD S3 archive (from e.g. boto3) and using pathlib.Path instances, as well as some updates for NEXRAD ORPG Build 19.0 changes.
  • Improve default date handling in parse_metar_file
  • PyProj >= 2.3 is now a required dependency for calculations, and CartoPy is only needed for related plotting capabilities.
  • PlotObs.level now defaults to None, or no subsetting.
  • Using standard library modules importlib.resources and importlib.metadata (and their backports) rather than pkg_resources from setuptools. This fixes errors getting MetPy's version from unconventional installs.

0.12.0

Version 0.12 (2020/01/05)

This is the first release that only supports Python 3.

API Changes

  • 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.

Highlights

  • 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
  • Added support for Python 3.8, dropped support for Python 2.7
  • 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.
