Abstract
A ground-based remote sounding instrument that uses a length-modulated radi ometer to measure the total atmospheric carbon monoxide (CO) column has bee n built. Measurements made in Toronto during August and September of 1994 s howed average CO concentrations of 125 to 150 parts per billion in volume ( ppbv, parts in 10(9)). Similar measurements made in October at a rural site 80 km north of Toronto showed concentrations of approximately 100 ppbv. Th e latter measurements are shown to agree with other simultaneous ground- an d satellite-based measurements. This instrument is an advanced prototype of the MOPITT (Measurements of Pollution in the Troposphere) satellite instru ment. (C) 1999 Optical Society of America.
