Description

CO2 Plus reports the concentration of carbon dioxide in the atmosphere, as measured by the U.S. NOAA's Mauna Loa Observatory [1].
The first value is the previous week's average, and the second value is the weekly average taken a year ago.
This watchface uses the API developed by HQCasanova [2].
CO2 Plus is configurable, allowing the user to choose from 6 date modes encompassing U.S. and European formats.
