In order to quantify the relative importance of the QBO cycle with respect to the annual variation in UV erythemal dose, we calculated the peak-to-peak amplitudes of the an- nual

We applied the procedure to a baseline analysis of the perfor- mance of a recently proposed solar UV occultation sensor (SMAS – Sun Monitor and Atmospheric Sounder) and pro- vide,

The role of vertical transport by cloud convection on the observed seasonal cycle of the surface concentration has been noted by the modelling study of CFCl 3 and CF 2 Cl 2 over..

The results of three series of simultaneous measurements of the mesospheric electric ®elds, ion density and conductivity carried out under di€erent geomagnetic conditions at polar

The results show that a direct relation between L and R is observed under the western phase of the QBO and there exists a saturation e€ect at R > 60: For R < 60 the

The physical reason for the failure of the one-¯uid theory is very simple: the ions are pushed upward, not downward, by an upward electric ®eld, and thus the magnetospheric ions

Contrary to the correlation of the intensity of the left-hand polarized ion-cyclotron waves to the proton temperature an- isotropy for quasi-perpendicular low-β cases, our

While a Reynolds number analogy has been used in for- mulating ℵ, because of the very large value of the damp- ing force, the kinematic viscosity, and the use of the Brunt-
