No worries - while that page has more longer term data, for visits to HVNP we tend to refer to: https://www.nps.gov/havo/air-quality-alert.htm
The "Charts" tab there has PM2.5 readings hourly and SO2 readings every 15-mins across several sites in the park for the day. It displays well on a mobile device and helps when deciding where to go when, based on emissions, winds, people's sensitivities, etc... Worth trying both and seeing what works best for your uses IMO.
