We have blogged a bit about the techniques and precision of atmospheric CO2 measurements (see here).  Now a new space-based instrument, the Atmospheric Infrared Sounder (AIRS), is enhancing our ability to measure CO2 concentration and to forecast it’s implications, including the feedback associated with increasing water vapor.
