0.2.0 (2020-06-19 Juneteenth)

  • NWIS has a simpler interface and improved functionality:
    • No need to use .get_data(); data is fetched automatically.
    • NWIS.df() creates dataframes using only the parts you want
      • .df(‘discharge’) returns a dataframe with only discharge data
      • .df(‘01585200’) returns all of the data for just this site
      • .df(‘flags’) returns a dataframe with the qualifier flags.
    • New and improved REPR: lists stations, parameters, and frequency for a dataset.
  • Saving data to a file:
    • the ‘file’ parameter for NWIS allows you to save your data locally
    • If the file doesn’t exist, NWIS requests the data and creates the file
    • Uses the parquet format for faster load times and smaller file sizes
  • Improved parsing of data from NWIS:
    • missing observations are noted & can be replaced with interpolated values
    • duplicates found & removed
    • unsorted data found & cleaned.
    • different frequencies raise a warning when resampled
  • parameterCd now accepts multiple parameters in request.
  • If parameterCd is not specified, then all available parameters will be requested (default).
  • hf.rating_curve(site) retrieves the current rating curve for a USGS site.
  • hf.peaks(site) retrieves the annual peak discharges for a USGS site.
  • hf.field_meas(site) retrieves the field data and notes used by the USGS to create a rating curve.
  • hf.stats(site, statReportType) retrieves Annual, Monthly, or Daily reports from the USGS.
  • hf.site_file(site) retrieves expanded site file.
  • hf.data_catalog(site) retrieves history of data collected at site.
  • Dropped Python 3.4 & 3.5 support, added 3.8.
