摘要: The fluxes of NO and NO2 have been measured at a grassland site in Colorado, United States. measurements were made using an enclosure technique during the period between Aug. 16, 1985, Nov. 15, 1985. ranged 0.028 65 ng N m−2 s−1 with average value for all 3.0 s−1. flux was found to increase rapidly increasing temperature. Large variations soil moisture also observed. Under dry conditions, present effluent from sampling but not when and/or vegetation covering moist. Overall, totalled approximately 10% emissions. results are compared NOx emission carried out elsewhere.
