1.1.1

AirSensor 1.1.1

• Changed examples to use PURPLE_AIR_API_READY_KEY instead of MY_API_READ_KEY.
• Added "Working with PurpleAir API Keys" article.
• When show_only is used, spatial bounding information is ignored in:
  pa_getSensorsData(), pas_downloadParseRawData() and pas_createNew().
• Updated pas_createNew() to be backwards compatible with MazamaSpatialUtils
  version 0.7.6.

1.1.0

AirSensor 1.1.0

Updates to accommodate data access through the PurpleAir API released in July of
2022. This API requires an API_KEY. Users of the package are required to obtain
their own credentials from PurpleAir.

For information, see:

• PurpleAir AIP

• PurpleAir Terms of service

• PurpleAir Data license

• PurpleAir Data Attribution

• Updated Mazama package dependency versions.

• Support for API keys.

• Replace sp package dependency with sf package.

• New versions of pas_createNew(), pas_downloadParseData(), pas_enhanceRawData()
  and pas_leaflet().

• Some column names in generated pas dataframes have changed to be more
  consistent with PurpleAir documentation.

• New versions of pat_downloadParseRawData(), pat_createNew().

• Updated package data and function reference examples.

• Removed package dependencies: httpcode

1.0.8

AirSensor 1.0.8

• Minor documentation updates.

1.0.7

AirSensor 1.0.7

• Minor documentation updates to clarify "state-of-health" calculations.
• Improved pattern matching for South Coast communities in pas_addCommunityRegion().
• Remove "Voc" column during pas_load() so that current and archival 'pas'
  objects can be easily merged. (Some early 'pas' objects contained some "Voc"
  data but this has never been a focus of the AirSensor package. Later 'pas'
  objects do not contain the "Voc" parameter.)
• pas_load() now properly handles loading of archival 'pas' objects prior to
  2019-08-02.

AirSensor 1.0.6

• Fixed documentation and included dataset encoding to UTF-8 standard.

1.0.5

AirSensor 1.0.5

• Improved monitor labeling in pat_externalFit() and pat_monitorComparison().

AirSensor 1.0.4

• Updated PAS baseUrl to 'https://www.purpleair.com/json?all=true'.

1.0.3

AirSensor 1.0.3

• Improved legend in pat_monitorComparision().

AirSensor 1.0.2

• CRAN submission tweaks.
• Spell check vignettes.

AirSensor 1.0.1

• CRAN submission tweaks.

1.0.0

AirSensor 1.0.0

• First public release.

0.9.19

AirSensor 0.9.19

• Added sensor_calendarPlot().

AirSensor 0.9.18

• Fix in pat_join() to handle older 'pat' objects with integer deviceID.

0.9.17

AirSensor 0.9.17

• Updated dependency to worldmet 0.9.2.
• sensor_pollutionRose() now searches for the nearest 2 met sites in case the
  first one has no data. This matches the behavior in sensor_polarPlot().
• Rebuilt all example_~ data files with AirSensor 0.9.17.
• Updated tests to match new example data.
• Removed all references to "Voc" in pas related functions as this field is
  not longer part of the PurpleAir .json file.
• Used MazamaCoreUtils "timezone linting" to ensure that timezones are always
  specified.
• Removed plantowerAlgorithm argument from pat_createPATimeseriesObject() as
  an attractive nuisance that could generate much confusion.
• Improved examples in several sensor_~() functions.
• Updated several articles.

AirSensor 0.9.16

• Restored sensor_polarPlot() and sensor_pollutionRose() functionality by
  upgrading to worldmet 0.9.1.

AirSensor 0.9.15

• Improved error handling in sensor_join().
• Fixed date range filtering bug in sensor_load().

AirSensor 0.9.14

• Added guarantees in multiple places that meta$ID and meta$deviceID for both
  pat and airsensor objects are of type "character". This fixes errors during
  joining of monthly files that may have been created with an earlier version of
  the package.

AirSensor 0.9.13

• For all PurpleAirQC_hourly_~() functions, returnAllColumns now returns a
  column of data for every parameter used in the QC algorithm.
• Suppressing deprecation warnings generated by (R version 3.5.3) stats::t.test()
  inside of PurpleAirQC_hourly_AB_01().
• Fixed PurpleAirQC_hourly_AB_01() to properly use the t-test p_value.
• Fixed PurpleAirQC_hourly_AB_01() to gracefully handle time periods when
  R's stats::t.test() function returns an error -- e.g. when an hourly subset
  contains insufficient data.
• Updated pas_downloadParseRawData() to guarantee that all "ID" parameters are
  of "character" type and not "integer".

0.9.12

AirSensor 0.9.12

• Added sensor_filterDatetime() function for times that are not aligned to
  date boundaries.
• Refactored sensor_load() to use sensor_join() and other internal functions
  for package consistency.
• Replaced internal use of validation function PWFSLSmoke::monitor_isMonitor()
  with package internal sensor_isSensor().
