04Caveats

Read before you use

What this edition’s numbers are and are not, worked out from the file itself.

The site’s method

152 distinct values among 220

The position is ours
Atmospheric Composition Analysis Group publishes values only. The order here sorts the published values, and the page says so wherever it prints one.
Which end is better
A higher value is the worse result.
Nothing missing
Every one of the 220 countries has every column.
