First results from an airborne GPS radio occultation system for atmospheric profiling
(Amer Geophysical Union, 2014-03-16)
Global Positioning System (GPS) radio occultation (RO) from low Earth-orbiting satellites has increased the quantity of high-vertical resolution atmospheric profiles, especially over oceans, and has significantly improved ...
Evaluation of uncertainty in gravity wave potential energy calculations through GPS radio occultation measurements
(Elsevier Sci Ltd, 2013-05)
The application of the Global Positioning System (GPS) radio occultation (RO) method to the atmosphere enables the determination of height profiles of temperature, among other variables. From these measurements, gravity ...
Assessment of precision in ionospheric electron density profiles retrieved by GPS radio occultations
(Elsevier, 2014-12)
The Constellation Observing System for Meteorology Ionosphere and Climate (COSMIC) is a six satellite radio occultation mission that was launched in April 2006. The close proximity of these satellites during some months ...
Stratospheric gravity wave momentum flux from radio occultations
(American Geophysical Union, 2016-02)
Triples of GPS radio occultation (RO) temperature data are used to derive horizontal and vertical gravity wave (GW) parameters in the stratosphere between 20 km and 40 km from which the vertical flux of horizontal momentum ...
A comparative and numerical study of effects of gravity waves in small miss-distance and miss-time GPS radio occultation temperature profiles
(Elsevier, 2010-05)
The Global Positioning System (GPS) Radio Occultation (RO) technique has global coverage and is capable of generating high vertical resolution temperature profiles of the upper troposphere and lower stratosphere with ...
Oscillation modes of humidity over the Amazon basin derived from GPS RO profiles
(Amer Geophysical Union, 2013-12)
The Global Positioning System radio occultation (GPS RO) technique provides vertical profiles of refractivity from which water vapor can be derived. It is possible to reproduce global, synoptic, and regional climatological ...
An improvement of the sensitivity of GPS radio occultation data to detect gravity waves through observational and modeling factors
(Elsevier, 2015-10)
There is a mid-latitude region to the East of the Andes Range in the Southern Hemisphere that exhibits ideal conditions for the generation of gravity waves (GW) by topography mainly during winter. The configuration favors ...
