Equatorial F-region plasma depletion drifts: latitudinal and seasonal variations

The equatorial ionospheric irregularities have been observed in the past few years by different techniques (e.g. ground-based radar, digisonde, GPS, optical instruments, in situ satellite and rocket instrumentation), and its time evolution and propagation characteristics can be used to study important aspects of ionospheric dynamics and thermosphere-ionosphere coupling. At present, one of the m...

Daily surface wind variations over the equatorial Pacific Ocean

Daily surface wind variations over the equatorial eastern Pacific Ocean during summer 1992 are documented, using hourly observations from the tropical atmosphere ocean moored buoy array. Diurnal and semidiurnal variations are apparent in the zonal wind component, with peak-to-peak amplitudes of a few tenths of a meter per second. The phase of the semidiurnal cycle in zonal wind is approximately...

Snowmelt detection over the Greenland ice sheet from SSM/I brightness temperature daily variations

[1] We propose a technique for monitoring snowmelt over the Greenland ice sheet between 1992 and 2005 based on the difference between ascending and descending brightness temperatures (DAV) measured either at 19.35or 37GHz by the Special Sensor Microwave Imager (SSM/I). Wet snow is detected when both brightness temperatures and DAV values exceed fixed thresholds. Differently from existing techni...
