Combining these measurements with calculations using a one-layer model, the total amount of N_2O in a vertical column is estimated to be 6.48×(10)^<18> molec. (cm)^<-2>. A simpler method using the transmittances at 2554.6 and 2575.0(cm)^<-1> gives practically the same result for the total amount of N_2O.}, pages = {28--36}, title = {Infrared measurements of total nitrous oxide at Tsukuba}, volume = {34}, year = {1984} }
