0.11.0

Version 0.11 (2019/09/30)

This is the FINAL RELEASE to support Python 2.7.

API Changes

  • MetPy's copy of the "viridis" colormap is deprecated. Use it directly from matplotlib instead.
  • Deprecated the tmpk_out argument for isentropic_interpolation; this will be removed in 1.0. Use temperature_out instead.
  • ageostrophic_wind now issues a FutureWarning due to an impending change to its function signature in 1.0--this will change the signature to ageostrophic_wind(heights, u, v, f, dx, dy) for better consistency with the rest of the library. To avoid this warning, import the function with from metpy.future import ageostrophic_wind.
  • Deprecated the bounds argument on Hodograph.plot_colormapped in favor of intervals to improve clarity on how to use the argument.
  • Removed previously deprecated:
    • lat_lon_grid_spacing: use lat_lon_grid_deltas instead
    • cdm module
    • GINIFile.to_dataset()

Highlights

  • Several SkewT fixes and enhancements, including reworking the transform so that it works in screen space; this helps it work much better on oddly shaped axes. On Matplotlib 3.2, this means that the SkewT maintains sensible data scaling. SkewT by default also now has sensible plot limits.
  • MetPy 0.10.x accidentally picked up a hard dependency on CartoPy, this has been removed
  • Expanded simplified plotting interface with more documentation and support for Barbs
  • Several bug fixes for lcl, el, lfc, and cape_cin
  • No longer require using .metpy.parse_cf() to activate coordinate identification with XArray
  • XArray accessor automatically converts problematic '%' units to 'percent'
  • Added unit support in reduce_point_density
  • wind_direction now supports specifying the convention (either 'to' or 'from') to support oceanographic applications (default remains 'from').
  • Improved numerical stability of geopotential<->height calculations
  • Added parsing of more combinations of weather symbols
  • Added specific_humidity_from_dewpoint, altimeter_to_station_pressure, altimeter_to_sea_level_pressure
  • heat_index now better matches NWS algorithm
  • Added angle_to_direction to convert wind direction in degrees to e.g. 'NE'
  • Added control of mask_undefined on apparent_temperature

0.10.0

Version 0.10 (2019-01-06)

API Changes

  • potential_vorticity_baroclinic was changed to take all 3D variables, with dimensions ordered: vertical, y, x.

Highlights

  • MetPy has gained a simplified plotting interface designed to mimic that of GEMPAK. It uses a handful of objects on which users set attributes to values to control the plot, requiring data in an xarray DataArray or Dataset. See MetPy's plotting examples for more information.
  • MetPy's xarray accessor now has its own versions of loc and sel that accept unit-ed values.
  • Added an n-point soothing function
  • moist_lapse and dry_lapse now accept an arbitrary starting (reference) pressure value.
  • potential_vorticity_baroclinic now works with data either on isobaric or isentropic surfaces.
  • MetPy now has state borders that match the boundaries of the county borders.
  • SkewT instances can now be created at an arbitrary rectangular location within a figure.
  • MetPy's calculations have been adjusted so that the values of constants can be overridden by changing the values in the constants module.

0.9.0

Version 0.9 (2018/08/27)

API Changes

  • Renamed get_wind_speed to wind_speed; the old name is still available but is deprecated and will be removed in 0.12
  • Renamed get_wind_dir to wind_direction; the old name is still available but is deprecated and will be removed in 0.12
  • Renamed get_wind_components to wind_components; the old name is still available but is deprecated and will be removed in 0.12

Highlights

  • Added support for cross-sections along arbitrary lat/lon paths
  • Added parcel_profile_with_lcl to compute the parcel profile and return values for the parcel profile, as well as the ambient pressure, temperature, and dew point that includes the lcl
  • Fixed corner case problems in some thermodynamic calculations by using parcel profiles including the LCL
  • Added function to get a matplotlib color from a GEMPAK color number
  • Added CartoPy map feature for U.S. counties
  • get_test_data will now automatically download and cache data files if the user is not running a git checkout of MetPy. This makes all of our test/example data much more easily available.
  • Added smooth_gaussian, which smooths a grid using a Gaussian distribution-shaped kernel; this is an analog of GEMPAK's gwfs
  • Fixed error reading newer NEXRAD Level 2 files

0.8.0

Version 0.8 (2018/05/17)

API Changes

  • lat_lon_grid_spacing has been deprecated in favor of lat_lon_grid_deltas. The latter gives properly signed values depending on the ordering of points in the lat/lon grid.
  • The deprecated upper air data reading support has been removed. Use the upper air support in siphon instead.
  • The function delete_masked_points has been renamed to _delete_masked_points, as it was not intended to be part of the supported API.
  • GINIFile.to_dataset(), which gives a netCDF4-python-like interface to the information in the file, has been deprecated. Instead, now an instance of GINIFile can be passed directly to xarray.open_dataset() to provide a similar interface. to_dataset() (as well as the non-public cdm module) will be removed in 0.11.

Highlights

  • MetPy now requires XArray. Using XArray, MetPy provides some custom accessors under the .metpy attribute on Dataset and DataArray. This allows simplified access to the underlying grid projection as a CartoPy projection, as well as simplified access to data as an array with units attached. (See the XArray_Projections.py example) MetPy calculation functions will also now automatically convert an XArray DataArray with units metadata into a proper array with units. Future releases of MetPy will improve the integration with XArray.
  • GINIFile now works directly as an XArray storage backend. See the updated GINI_Water_Vapor.py example for details. Support for Unidata NEXRAD composites in GINI format was also added.
  • MetPy's colortables are now available from metpy.plots.colortables rather than needing to do metpy.plots.ctables.registry.
  • Fixed a few corner cases with isentropic interpolation, including problems with columns of entirely missing data (frequently encountered with NARR data)
  • lfc and el now work with arbitrary parcel profiles
  • Gradient and related functions now properly propagate masked values
  • Text and time formatting for add_timestamp() are now configurable
  • New calculations
    • Absolute vorticity
    • Ageostrophic wind
    • Apparent temperature (combines wind chill and heat index)
    • Brunt-Väisälä frequency and period
    • Critical angle (severe weather parameter)
    • Dewpoint (from specific humidity)
    • Exner function
    • Inertial advective wind
    • Parse angle (converts strings like "ESE" to degree values)
    • Potential temperature to temperature
    • Potential vorticity
    • Q Vector
    • Saturation equivalent potential temperature
    • Static stability
    • Wet bulb temperature
  • Other assorted bug fixes
  • Reminder: MetPy plans to drop support for Python 2.7 in Fall 2019

0.7.0

Version 0.7 (2018/01/04)

API Changes

  • The default dimension ordering for functions in kinematics (i.e. when dim_order is not passed) has changed from "xy" to "yx". This lets more data work out of the box with these functions, and has been warned since 0.5.1
  • Renamed h_convergence and v_vorticity to divergence and vorticity, respectively. These latter names are simpler and more accurate. The old names are still available for old code, but are deprecated and will be removed in 0.9.
  • convergence_vorticity and shearing_stretching_deformation are deprecated, and will be removed in 0.9. These functions existed as performance optimizations, but new calculation internals renders them unnecessary.
  • The parameter sblcl for significant_tornado has been renamed to surface_based_lcl_height to improve clarity. This only affects users who were passing by keyword argument.
  • Changed relative_humidity_wet_psychrometric, relative_humidity_from_mixing_ratio, and relative_humidity_from_specific_humidity to return values as unitless ratios rather than percentages, for better symmetry with the rest of the library.

Highlights

  • Added our own functions for first_derivative, second_derivative, gradient, and laplacian. These are 3 point finite difference calculations that handle irregularly spaced grid points.
  • Added function to calculate x,y grid spacing for latitude/longitude grids
  • Added table of equivalencies between GEMPAK functions and Python. This is an on-going effort to provide a resource for migrating from GEMPAK.
  • Added ability to add_timestamp to add outlined text
  • New calculations
    • Thickness (using hypsometric formula)
    • Geopotential to/from height
    • Mixing ratio from relative humidity
    • Moist static energy
    • Dry static energy

0.6.1

Version 0.6.1 (2017/11/04)

API Change

  • Small API change to change storm_relative_helicity to take heights, as well as an argument for depth. This fixes a bug in the original design of the function where the default bottom was 0, which is below the first level of most soundings.

Highlights

  • Fix bugs in corner cases of get_layer, precipitable_water, el, and bulk_shear
  • Fix use of units with plot_colormapped on Hodograph
  • Fix lack of projection of wind barbs in StationPlot when using CartoPy
  • Enable interpolation by default when calling shade_cape and friends for SkewT
  • Fixed up definitions of CAPE and CIN to be net integrals above and below the LFC, respectively
  • Add MetPy logo to examples

0.6.0

Version 0.6 (2017/09/15)

Summary

API Changes

  • MetPy's upper air data download functionality has been deprecated, and will be removed in version 0.8. This functionality can now be found in Siphon 0.6.
  • equivalent_potential_temperature has changed to explicitly take a dewpoint parameter. The previous implementation of this calculation was only valid for pressure and temperature corresponding to the lifted condensation level (LCL). The new formula accepting dewpoint explicitly is valid everywhere.

Other Changes

  • Additional calculations
    • CAPE/CIN, including most unstable and surface-based
    • precipitable water
    • Montgomery streamfunction
    • supercell composite
    • significant tornado parameter
    • frontogenesis and (shear, stretching, total) deformation
    • relative humidity
    • storm relative helicity
    • Bunker's storm motion
  • Added isentropic interpolation
  • Added support for 1D interpolation on multi-dimensional arrays
  • Added example for interpolating from sigma coordinates to pressure coordinates
  • Support for coloring layers on a hodograph
  • Support for coloring wind barbs on skew-T
  • Added function for adding MetPy and/or Unidata logos to figures
  • Added warnings to get_wind_components and coriolis_parameter when it seems that degree values are accidentally passed in without units (which treats them as radians)
  • Simplified turning on clipping on StationPlot

Dependency Updates

  • Minimum supported NumPy version is now 1.10.0
  • Minimum supported Pint version is now 0.8
