MetPy 1.1.0 Released

Version 1.1.0 of MetPy, a collection of tools in Python for reading, visualizing, and performing calculations with weather data, has been released. Highlights of the new release include:

  • 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
