Indpls-Washington Park Data by Site by Date (all parameters)

Use this form to retrieve hourly data collected at Indpls-Washington Park. 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.

Use the controls below to select a different date or time format and to control cell highlighting based on measured ozone, sulfur dioxide, nitrogen dioxide or PM-2.5 or PM-10 levels. Click on the Generate Report button once you have made your selections. Click on the Plot Data button once the tabular report has been generated to open a separate window containing data plots.

 R - Data from this instrument meets EPA quality assurance criteria for regulatory purposes.

Key to Ozone Highlight Colors:

Hourly ozone levels have been mapped to a set of surrogate values based on custom 1-hour breakpoints.
The table below shows the levels, color-coding, and suggested actions for the 1-hour surrogate.

Ozone levels in this range are projected to be moderate based on the one-hour surrogate calculation for Ozone.
  • Unusually sensitive individuals may experience respiratory symptoms.
  • Unusually sensitive people should consider reducing prolonged or heavy outdoor exertion.

PLEASE NOTE: This data has not been verified by the IDEM and may change. This is the most current data, but it is not official until it has been certified by our technical staff. Data is collected from IDEM ambient monitoring sites and may include data collected by other outside agencies. This data is updated hourly.
