In bcgov/rcaaqs: Tools to implement CAAQS analysis for air quality

rcaaqs 0.3.1.9000

• Finalized methods for SO2 and NO2
• Output CAAQS status and management status for each metric
• Function wrappers for each CAAQS metric that return an object of class caaqs plus an additional class based on the metric (one of "pm2.5_annual" "pm2.5_24h", "o3", "so2_1yr", "so2_3yr", "no2_1yr", "no2_3yr"). This object contains the final caaqs results plus the intermediate data sets.
• "Extractor" functions to get the the caaqs results or intermediate data from the caaqs object:
  • get_caaqs():
  • caaqs results
  • get_hourly():
  • so2_1yr, no2_1yr: Hourly values used for annual average
  • get_daily():
  • pm2.5_24h, pm2.5_annual: Daily average
  • o3, so2_3yr, no2_3yr: Daily maximum
  • get_yearly():
  • pm2.5_24h: Annual 98th percentile daily average
  • pm2.5_annual: Annual average of daily averages
  • o3: Annual 4th highest daily maximum
  • so2_1yr, no2_1yr: Annual average of hourly values
  • so2_3yr: Annual 99th percentile of daily maximums
  • no2_3yr: Annual 98th percentile of daily maximums
  • get_three_yr_rolling():
  • pm2.5_24h, pm2.5_annual, o3, so2_3yr, no2_3yr: Three-year rolling average of the yearly value.
• New function caaqs_management() to add management categories to a caaqs object, and optionally exclude dates from the analysis which have been deemed influenced by exceptional events (such as wildfire) or transboundary flows (see the CAAQS manuals for how these are determined).
• plot_ts() now expects a caaaqs object as input (the result of running one of the *_caaqs() functions).
• New function, assign_airzone to determine where sites are located in airzone shapefiles
• Removed airzone map, use maps from bcmaps package instead
• Updates to documentation
• Improved coding consistency with respect to argument names
• Use lubridate functions rather than internal date/time functions
• Update CAAQS for PM2.5 and Ozone
• Update to dplyr v1.0 and tidyr v1.1
• Allow plot_station_instruments() to use any station column
• Add overlap points to plot_station_instruments()
• Add plot_caaqs() function to plot annual caaqs values as barplots.
• Add plotting details for SO2 and NO2

rcaaqs 0.3.1

• Fixed plotting functions to more reliably plot special characters (e.g., mu and superscript)

rcaaqs 0.3.0

• Made format_date function defunct, and replaced it with format_caaqs_dt, which puts the datetime into the correct timezone in POSIXct, and automatically assigns readings with the previous hour by subtracting one second from the timestamp.
• export round_caaqs function.
• Add more robust checking of columns in core functions (#23)

rcaaqs 0.2.0

• Added a NEWS.md file to track changes to the package.
• Methods for PM2.5 now deal with exceptions to data completeness criteria (#13, #14)
• Methods for ozone (#2, #14)
• Preliminary methods for SO2 (#11, #14) and NO2 (#12, #14)
• Methods for dealing with exceptional events and transboundary flows (#5, #14)
• Added Aman Verma (@nograpes) as a package author for work on #2, #5, #11, #12, #13, #14 (via #17)
• Ensure rounding follows the CCME 'Guidance Document on Achievement Determination Canadian Ambient Air Quality Standards for Fine Particulate Matter and Ozone' standards (#21)
