We monitor outdoor air temperature, wind speed and direction, and relative air humidity at a few air quality monitoring sites. The results are available as a graph or table. The tabs allow you to select which monitoring results you want to view. In the graphs, you can select one or more monitoring items that you want to view. The monitoring results are displayed hourly. You can select a day, week, or month as the reference period. The monitoring results are unverified hourly averages.
