Avaliação de perfis atmosféricos de rádio ocultação GPS do satélite CHAMP sobre a América do Sul
(Sociedade Brasileira de Meteorologia, 2010-06-01)
Com o advento dos satélites artificiais Global Positioning System (GPS) em conjunto com os satélites Low Earth Orbiting (LEO), surge a Rádio Ocultação GPS (RO GPS), técnica que permite obter remotamente perfis atmosféricos ...
A gravity wave analysis near to the Andes Range from GPS radio occultation data and mesoscale numerical simulations: Two case studies
(Elsevier, 2009-08)
Global maps of potential wave energy per unit mass, recently performed with the Global Positioning System (GPS) Radio Occultation (RO) technique and different satellite missions (CHAMP and SAC-C since 2001, GRACE and COSMIC ...
A comparative analysis of the temperature behavior and multiple tropopause events derived from GPS, radiosonde and reanalysis datasets over Argentina, as an example of Southern mid latitudes
(Universidad Católica Argentina, 2009)
Abstract: Recent research on climatologies for temperature structure and tropopause parameters in the tropics, based on radiosonde, satellites data and model reanalysis show good agreement between radiosonde (RS) and data ...
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 ...
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 ...
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 ...
On the determination of gravity wave momentum flux from GPS radio occultation data
(European Geosciences Union, 2013-11)
Global Positioning System (GPS) radio occultation (RO) is a well-established technique for obtaining global gravity wave (GW) information. RO uses GPS signals received by low Earth-orbiting satellites for atmospheric limb ...
Agunas aplicaciones recientes de la técnica de radio ocultamiento satelital en el estudio de procesos atmosféricosSome recent applications of radio occultationtechnique in atmospheric proceses
(Universidad Nacional del Comahue. Departamento de Geografía, 2013-12)
En los últimos años, el uso del principio de radio ocultamiento (RO) satelital para observar la atmósfera terrestre y el clima aprovecha los ocultamientos bajo el horizonte del sol, de la luna, de las estrellas y principalmente ...
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 ...
A gravity waves study close to the Andes mountains in Patagonia and Antarctica with GPS radio occultation observations
(Copernicus Publications, 2010-03)
We first study the seasonal and geographical behavior of gravity wave activity in the lower stratosphere over the southernmost Andes mountains and their prolongation in the Antarctic Peninsula by global positioning system ...
