Odd nitrogen formed by energetic electron precipitation as calculated from TIROS data

Daily odd nitrogen formation due to energetic electron precipitation has been calculated for 840101 through 841231. Electron energy spectra between 4.25 and 1050 keV were used as derived from TED and MEPED observations made aboard NOAA spacecraft. Results indicate the importance of electron precipit...

Description
Summary:Daily odd nitrogen formation due to energetic electron precipitation has been calculated for 840101 through 841231. Electron energy spectra between 4.25 and 1050 keV were used as derived from TED and MEPED observations made aboard NOAA spacecraft. Results indicate the importance of electron precipitation to the middle atmospheric NOy budget between 70 and 111 km. The column NOy source for 42≤Z≤111 km and for invariant latitudes between 63° and 76° in both hemispheres is calculated to be ≈13 times that of the global source of NOy derived from N2O. This source is larger in the southern hemisphere and is dominated by electrons which deposit their energy above 80 km.
