The following have been deprecated and will be removed from Py-ART after
one additional point release (included in 1.8.0, removed in 1.9.0).

• The sounding_heights, sounding_wind_speeds, and sounding_wind_direction
  parameters of the pyart.correct.dealias_fourdd function. These parameters
  should now be specified in the sonde_profile argument.
• The pyart.correct.find_time_in_interp_sonde function. With the availability
  of the pyart.io.read_arm_sonde_vap function this function is no longer
  needed.

Py-ART version 1.6.0

Version 1.6.0 is the result of 5 months of work by 7 contributors.

contribution to Py-ART.

Highlights of this release:

* Support for writing Universal format (UF) files. 
* Support for reading NEXRAD Level 2 message 1 format files. 
* Specific field and scans can be specified when reading NEXRAD files.

Please note that this will be the last release to officially support Python
2.6 and 3.3. The next version of Py-ART will support Python 2.7, 3.4
and 3.5.

The following have been deprecated and will be removed from Py-ART after
one
additional point release (included in 1.7.0, removed in 1.8.0).

• The 'axes' attribute of the Grid class, the elements found in this
  dictionary
  can now be found elsewhere in the Grid class.
• pyart.io.add_2d_latlon_axis, the information provided by this function is
  now available in Grid attributes.
• The Grid class is initialized using a new set of parameters. Support for
  creating Grid instances from using the older parameters is available using
  the from_legacy_parameters method, which will be removed in Py-ART 1.8.0.
• The pyart.io.read_legacy_grid function was added to read in netCDF files
  containing gridded radar data as produced by Py-ART 1.5.0 and prior.
  This function will be removed in Py-ART 1.8.0.
• pyart.graph.RadarDisplay_Airborne, now pyart.graph.AirborneRadarDisplay
• The 'grid_lons', 'grid_lats' and 'proj' attributes of the GridMapDisplay
  class. This information can be found in the Grid attributes.
• The 'starts', 'ends', 'time_begin', 'radar_name', 'x', 'y', and 'z'
  attribute
  of the RadarDisplay class and subclasses. This information can be
  found in
  attributes of the Radar class.
• pyart.core.corner_to_point, use pyart.core.geographic_to_cartesian
• pyart.core.is_vpt, now found at pyart.util.is_vpt
• pyart.core.to_vpt, now found at pyart.util.to_vpt

Additionally the following portions of the non-public API are also
deprecated
in the same manner.

• pyart.graph.common.corner_to_point
• pyart.io.common.radar_coords_to_cart
• pyart.graph.common.radar_coords_to_cart
• pyart.graph.common.sweep_coords_to_cart
