Days with the 24-hour PSI above 100 in Singapore each year since 2014

How many days each year the 24-hour PSI went above a level in Singapore, from NEA through data.gov.sg.

Settings

Measure

The highest hourly 24-hour PSI of the five regions each day.

Level

A day counts when its highest 24-hour PSI is above the level.

Place

Malaysia's API readings are not on Atlas's reviewed list: their terms are not cleared.

From the year

NEA's file starts on 1 Apr 2014.

Next, Atlas shows the plan it made from these settings. Then you run it and get the chart, the table, About this data and the downloads.

What you get

Columns over time, with the table, About this data, a second source where Atlas has one, and PNG and SVG downloads. You can also make a short video of it.

Sources

Notes

The NEA file starts on 1 Apr 2014, so 2014 counts April to December only.

The current year runs to the last day Atlas read, so it is not a full year.
