Common Questions
What is Atmospheric Carbon Dioxide (co2)?
Atmospheric Carbon Dioxide is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms, found in the gas state at room temperature. In the air, Atmospheric Carbon Dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.
Source: https://en.wikipedia.org/wiki/Carbon_dioxideWhat is Atmospheric Carbon Dioxide (co2) used for?
Atmospheric Carbon Dioxide is used as a refrigerant, in fire extinguishers, for inflating life rafts and life jackets, blasting coal, foaming rubber and plastics, promoting the growth of plants in greenhouses, immobilizing animals before slaughter, and in carbonated beverages. And most improtantly it is food for all plants on earth.
What does PPM mean?
PPM is an abbreviation for "parts per million" and it also can be expressed as milligrams per liter (mg/L). This measurement is the mass of a chemical or contaminate per unit volume of water. Seeing ppm or mg/L on a lab report means the same thing.
One ppm is equivalent to the absolute fractional amount multiplied by one million. A better way to think of ppm is to visualize putting four drops of ink in a 55-gallon barrel of water and mixing it thoroughly. This procedure would produce an ink concentration of 1 ppm. Some other analogies that may help you visualize the scale involved with ppm. One ppm is like:
- one inch in 16 miles,
- one second in 11.5 days,
- one minute in two years.
An even smaller concentration measurement is parts per billion (ppb). One ppb is one part in 1 billion. Because a ppb is a much lower concentration, some analogies would be :
- one sheet in a roll of toilet paper stretching from New York to London,
- one second in nearly 32 years, or
- one pinch of salt in 10 tons of potato chips.
Data Information
The uncertainty in the global monthly mean is estimated using a monte carlo technique that computes 100 globally-averaged time series, each time using a slightly different set of measurement records from the NOAA ESRL cooperative air sampling network. The reported uncertainty, 0.13 ppm, is the mean of the standard deviations for each monthly mean using this technique. Please see Conway et al., 1994, JGR, vol. 99, no. D11. for a complete discussion. Units are ppm. CO2 expressed as a mole fraction in dry air, micromol/mol, abbreviated as PPM.
NOTE: In general, the data presented for the last year are subject to change. depending on recalibration of the reference gas mixtures used, and other quality control procedures. Occasionally, earlier years may also be changed for the same reasons. Usually these changes are minor.
