Use this form to retrieve hourly data collected at Polson-MT. 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. 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. 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.
