The short version

  • Only EPA AirNow has a free tier, so it costs nothing to try first.
  • Each has a real cost: EPA AirNow air quality data availability depends on nearby monitoring stations, can show no data found near a location when no monitor is close enough; ClearAg the Internet Archive's capture of clearag.com on 21 December 2018 shows it redirecting to iteris.com/clearag, confirming ClearAg was owned and sold by Iteris, Inc. (agriculture weather analytics: soil moisture, crop growth and health, spray conditions, irrigation and harvest readiness modules) before the product later moved under DTN's Agribusiness line.
  • They diverge on capability: EPA AirNow covers Official AQI data, ClearAg covers Spray window predictions.
