Iridescence Reveals the Formation and Growth of Ice Aerosols in Martian Noctilucent Clouds

open access: yesGeophysical Research Letters, Volume 51, Issue 23, 16 December 2024.
Abstract Water and carbon dioxide each form mesospheric clouds on Mars. At such altitudes (40–100 km), clouds may remain sunlit for part of the night. We describe a previously unreported, visually spectacular season of iridescent, noctilucent clouds visible in early southern autumn from the Curiosity rover's site in Gale crater.

Dust Dynamics in Gale Crater Observed Using the Line‐Of‐Sight Extinction Through 3,663 Sols of the Mars Science Laboratory Mission

open access: yesJournal of Geophysical Research: Planets, Volume 129, Issue 10, October 2024.
Abstract The Curiosity Rover has been exploring the Gale Crater using the on‐board Navigation Camera to monitor the line‐of‐sight (LOS) dust extinction within the crater. Previous studies of the line‐of‐sight extinction have shown an annual trend where a minimum in extinction occurs around Ls = 100° and a maximum occurs around Ls = 300°.

Direct Measurements of Dust Settling Velocity Under Low‐Density Atmospheres Using Time‐Resolved Particle Image Velocimetry

open access: yesGeophysical Research Letters, Volume 51, Issue 15, 16 August 2024.
Abstract Dust dynamics influence planetary atmospheres. However, the settling velocity of dust—and thus its residence time in the atmosphere—is often mispredicted. Challenging, indirect experiments involving few ideal particles revealed that dust settling velocity deviates from Stokes' law under rarefied atmospheres.

Dust Emissions on Mars From Phoenix Lidar Measurements in Relation to Local Meteorological Conditions

open access: yesGeophysical Research Letters, Volume 51, Issue 14, 28 July 2024.
Abstract The diurnal cycle of dust aerosols on Mars is studied by analyzing lidar observations at the Phoenix landing site under cloud‐ and fog‐free conditions and in the absence of elevated, long‐range transported dust layers. There is a pronounced diurnal cycle in the dust‐layer height with minimum heights of 4–6 km occurring between 11:00 and 17:00 ...

Actitudes de aculturación y prejuicio étnico en los distintos niveles educativos: un enfoque comparado

open access: yesRevista Electrónica Interuniversitaria de Formación del Profesorado, 2008
La inmigración genera en los países receptores importantes repercusiones demográficas, económicas, sociales y educativas. Las migraciones internacionales que se producen en la actualidad producen cambios fundamentales en los países de acogida, tanto a ...
