Observing Earth's atmosphere with radio occultation measurements using the Global Positioning System

open access: yes, 1997
The implementation of the Global Positioning System (GPS) network of satellites and the development of small, high-performance instrumentation to receive GPS signals have created an opportunity for active remote sounding of the Earth's atmosphere by ...

Temperature Trends and Anomalies in Modern Satellite Data: Infrared Sounding and GPS Radio Occultation

open access: yesJournal of Geophysical Research: Atmospheres, 2018
Trends in monthly average, zonal average temperature in the stratosphere as retrieved from highly accurate modern satellite data are intercompared and compared with climate reanalyses from 2003 through 2014.

The dynamic spectral signatures from Lunar Occultation: A simulation study [PDF]

open access: yesarXiv, 2018
Lunar occultation, which occurs when the Moon crosses sight-lines to distant sources, has been studied extensively through apparent intensity pattern resulting from Fresnel diffraction, and has been successfully used to measure angular sizes of extragalactic sources. However, such observations to-date have been mainly over narrow bandwidth, or averaged

Reducing representativeness and sampling errors in radio occultation-radiosonde comparisons

open access: yes, 2018
. Radio occultation (RO) and radiosonde (RS) comparisons provide a means of analyzing errors associated with both observational systems. Since RO and RS observations are not taken at the exact same time or location, temporal and spatial sampling errors ...
