Indpls-Harding St Data by Site by Date (all parameters)

Use this form to retrieve hourly data collected at Indpls-Harding St. Although this is the most current data, it is not considered official until it has been certified by the technical staff. This information is updated hourly.

This web page provides the most current hourly averaged data available. Our convention for time-tagging data is the beginning of each hour. For example, values shown for the noon hour are based on measurements taken from noon to 1:00 p.m. The noon average will not be calculated until after 1:00 p.m. The noon average will then be available on our external server from 1:15 p.m. to 1:30 p.m. This results in an apparent one-hour time lag in the data. We also present our data in Local Standard Time for each measuring site. For most of Indiana this is Eastern Standard Time. During Daylight Savings, this introduces another apparent one-hour time lag in the data.

Maximum values for each parameter are bold within the table. Minimum values are bold italic.
 R - Data from this instrument meets EPA quality assurance criteria for regulatory purposes.

Key to Sulfur Dioxide Highlight Colors:

Sulfur Dioxide levels have been mapped to colors based on the national one-hour standard levels.
The table below shows the levels, color-coding, and suggested actions for the one-hour standard.

Sulfur Dioxide levels in this range are projected to be unhealthy for sensitive groups based on the national one-hour standard for Sulfur Dioxide.
  • Increasing likelihood of respiratory symptoms, such as chest tightness and breathing discomfort, in people with asthma.
  • People with asthma should consider limiting outdoor exertion.
