Air Pollution: Remote Detection of Several Pollutant Gases with a Laser Heterodyne Radiometer | R T Menzies
; M S Shumate
; | Date: |
3 May 1974 | Journal: | Science, 184 (4136), 570-572 | Abstract: | An infrared heterodyne radiometer with a spectral resolution of 0.04 reciprocal centimeters has been used to remotely detect samples of ozone, sulfur dioxide, ammonia, and ethylene at room temperature, and samples of nitric oxide at 390K. Each gas was observed in a background of nitrogen or oxygen at atmospheric pressure. Sensitivities to some of these gases are adequate for detection of ambient concentrations as low as a few parts per billion. | Source: | PubMed, pmid17755034 doi: 10.1126/science.184.4136.570 | Services: | Forum | Review | Favorites |
