Publikováno v: Science (New York, N.Y.). 288(5470)

Upper Atmosphere Research Satellite observations indicate that extensive denitrification without significant dehydration currently occurs only in the Antarctic during mid to late June. The fact that denitrification occurs in a relatively warm month i

Observations of the stratosphere by the CLAES instrument on UARS

Autor: J. L. Mergenthaler, A. E. Roche, J. B. Kumer, W. G. Uplinger

Publikováno v: Optical Society of America Annual Meeting.

The Cryogenic Limb Array Etalon Spectrometer (CLAES) was launched by the Space Shuttle in September 1991 as an instrument on the Upper Atmospheric Research Satellite (UARS). It measures infrared emission from the limb of the Earth's atmosphere in nin

Photon emission from suprathermal helium ions in a partially ionized hydrogen gas

Autor: J. L. Mergenthaler

Publikováno v: The Astrophysical Journal. 199:770

The relative intensity and profiles of He i lambda5876, He ii lambda4686, and He ii lambda3203 have been calculated using a suprathermal-ion model for broad emission lines in Seyfert galaxies and quasars. With the results of this calculation it may b
