Digital filtering, calibration and correlation analysis of radar-echoes from the tropo and stratosphere

VHF-radars have been successfully used for remote sensing of the lower and middle atmosphere. The received radar-echoes are digitized and these raw data are processes in several sequential steps. By digitally filtering the raw data which is equivalent to a compression or a coherent integration, the ...

Vertical transport in the tropo-stratosphere by intermittent turbulence: a simultation study

The possibility of a slow depletion of stratospheric ozone in reactions with pollutants inadvertently released in the lower atmosphere has received considerable attention over the past decade (see e.g. Kruger ad Setlow, 1982). Production and loss processes alone cannot be used to account for budgets ...

Mesospheric wind estimation with the Jicamarca MST radar using spectral mainlobe identification

MST (mesosphere, stratosphere, troposphere) radar observations at Jicamarca use four antenna beams, one vertical, others tilted to the east, west, and south, to detect the scattered pulse returns from mesospheric heights (∼55–85 km). Doppler shifts of scattered returns, estimated by fitting the observed ...

Equatorial and low latitude ionospheric effects during sudden stratospheric warming events

The sources of ionospheric forcing are from above (solar and magnetospheric forces), internal (chemistry, local neutral dynamics), and from below (lower atmosphere). In this work we review the observed ion-neutral coupling effects at equatorial and low latitudes during large meteorological events ...
