What You Get in the Rain Gauge download

The Rain Gauge data download is a CSV file containing rainfall measurements recorded at 15 minute intervals captured from the rain gauge system. Each table is QA/QC'd by ALCOSAN.

What You Get in the Pixel/Basin EOM Dataset download

Each Pixel/Basin EOM Dataset download (5 or 15-Min) is a zip file that contains:

  • Shapefiles (folder)
    • 1km-grid_3rww_2313_sp.shp - gauge adjusted radar rainfall analysis pixels 
    • rfmgrossdelineations_sp.shp
    • rfmsheds_withnonrfmareas_sp.shp
  • MMMYYY_DelinID_15min.zip or MMMYYY_DelinID_5min.zip, where MMMYYYY is Month Year (e.g., Mar2019)
    • rainfall by sewershed. Each sewershed is a single CSV file in the zip file.
    • this data will join to the rfmsheds_withnonrfmareas_sp.shp shapefile
  • MMMYYY_DS_METERNA_15min.zip or MMMYYY_DS_METERNA_5min.zip, where MMMYYYY is Month Year (e.g., "Mar2019" )
    • rainfall by flow monitor. Each flow monitor is a single CSV file in the zip file.
    • this data will join to the rfmgrossdelineations_sp.shp shapefile
  • RYYMM_pixels_15min.zip or RYYMM_pixels_5min.zip, where YYMM is Year Month (e.g., "1903" is March 2019) 
    • rainfall by pixel for the month.
    • Each pixel is a single CSV file in the zip file.
    • this data will join to the 1km-grid_3rww_2313_sp.shp shapefile
