Determination of upper flammability limits of C[sbnd]H[sbnd]O compounds in air at reference temperature and atmospheric pressure
(2017-01-15)
The objective of the present article was to develop and validate a method for the determination of the upper flammability limits (UFLs) in air, at atmospheric pressure and reference temperature, of flammable compounds ...
Ship-borne VHF radar for mesospheric and ionospheric research
(Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 2000)
This paper describes a VHF coherent radar installed on board the Peruvian research vessel "Humboldt". The system has been designed and developed at Jicamarca Radio Observatory. The radar's antenna is a COCO array of 21 x ...
Recent advances in equatorial, low- and mid-latitude aeronomy
(Elsevier, 2013-10)
This special issue of the Journal of Atmospheric and Solar–Terrestrial Physics on “Recent Advances in Equatorial, Low- and Mid-latitude Aeronomy” contains selected papers presented at the 13th International Symposium on ...
Lower ionosphere monitoring by the South America VLF Network (SAVNET): C region occurrence and atmospheric temperature variability
(American Geophysical Union, 2013-10)
Daily profiles of phase measurements as observed on fixed VLF paths generally show a transient phase advance, followed by a phase delay, for about 90 min after sunrise hours. This is indicative of a reflecting ionospheric ...
Frequency domain interferometry observations of tropo/stratospheric scattering layers using the MU radar: Description and first results
(American Geophysical Union, 1990-11)
This paper describes the first results of the implementation of frequency domain interferometry (FDI) using the Middle and Upper (MU) atmosphere radar. A new method of using this FDI data is introduced, which is shown to ...
First observation of the upper stratospheric vertical wind velocities using the Jicamarca VHF radar
(American Geophysical Union, 1993-10)
The Jicamarca VHF radar (50 MHz) has detected atmospheric echoes in the so-called "gap region" from 30 to 60 km heights. These echoes are, for the first time, discriminated from clutter echoes, using both co-polarized ( ...
Report of MSG-6 on the scientific aspects of an international equatorial observatory (IEO)
(Instituto Geofísico del Perú, 1983)
MSG-6 has been set up to study this on the basis that there is need to have observatories very close to the equator so that we may understand equatorial dynamics much more precisely than we do now. Such observatories, ...

Gravity waves observed by the Jicamarca VHF radar in the equatorial upper stratosphere
(1986)
Internal gravity waves are known to play an important role in dynamics of the middle atmosphere. They can transport momentum flux from lower atmosphere to upper atmosphere and sometimes break mean flows or large-scale ...
