 The relationship between MRI_87 scale and WMO mole fraction scale is given by :
WMO = 5.451 + 0.9741 × (MRI_87) + 2.7699 × 10-5 × (MRI_87)2. This equation is only tentative, and may be changed considerably in the future.

 04/86- : Air samples are collected continuously through an air intake at 1.5 m above the ground.
02/92- : Air samples are collected continuously through an air intake installed on the meteorological tower at 200 m above the ground with a copper tube which is coated on the outside by polyvinyl chloride serving as the sample line.
04/96- : Air samples are collected continuously through an air intake installed on the meteorological tower at 25 m above the ground with a copper tube which is coated on the outside by polyvinyl chloride serving as the sample line.
