How to use this page

• You can specify a period of days and then click the  UPDATE  button to see data within this period.
• Data resolution will drop as the number of days displayed increases. To obtain full resolution, view one day at a time.
• You can see the value of each data point by hovering the cursor on each line.
• To zoom in, use the mouse to click and drag a rectangular window on the graph. (Vertical axis range may change for displaying optimal data range).
• Use the "Reset zoom" button to restore previous zoom level.
• To switch on and off the line on the graph, click on the corresponding legend entry, e.g "Carbon dioxide (ppm)".
• If you cannot access certain dates, it might because data is not available for that period.
• Data gaps can be caused by various technical or non-technical issues.
• You may notice that the CO₂ readings drift over time. This is an instrument calibration issue. We are working on correcting the readings, but in the meantime, you can view the raw data.
  

We are working on a video to better show you how to use this page. It will be published on this page as soon as it's ready.
