TL;DR: In this article, the authors investigated the quasi-3-day UFK wave and its effects on the variations of the ionosphere at low latitudes and midlatitudes using coordinated observations of both the atmosphere and ionosphere during the January 2010 URSI World Day campaign.
Abstract: [1] Recent studies of the equatorial ionosphere have found evidence of forcing by atmospheric Ultra Fast Kelvin (UFK) waves. This study investigates the quasi-3-day UFK wave and its effects on the variations of the ionosphere at low latitudes and midlatitudes using coordinated observations of both the atmosphere and ionosphere during the January 2010 URSI World Day campaign. The global maps of TEC from the IGS ground-based GPS product demonstrate a 3-day periodic variation during January 15–25. This variation has the largest amplitude at 15° magnetic latitude and extends into lower latitudes. Simultaneously, a 3-day wave is observed in the mesosphere in the zonal wind measurements by a meteor radar at the magnetic equator. The latitudinal range of the TEC variation (20°S–20°N) is also consistent with that of the 3-day wave. The Incoherent Scatter Radar (ISR) observations show a 3-day signature in vertical ion drifts over Jicamarca (11.9°S, 76°W) and in the electron densities in the top side of ionosphere measured from Millstone Hill (42.6°N, 71.5°W). This signature is consistent with the fountain effect in the equatorial region, and shows the impact on the topside ionosphere at midlatitudes. The UFK wave is trapped within ±30° geographic latitude, but this study shows that the effects of the wave could reach the ionosphere at the higher latitude even as high as 40°N (50°N magnetic latitude).

TL;DR: In this paper, satellite derived aerosol optical depth (AOD) and the wind data obtained from the NCEP-NCAR reanalysis were used to study the regional distribution of aerosols over the Indian Ocean and the influence of long-range transport during the Asian dry period of November-April of 1996-1999.

TL;DR: A review of these recent findings and presents the interaction of solar wind with the Moon in a new perspective is presented in this paper, where the authors provide a review of the recent findings.
Abstract: Characterised by a surface bound exosphere and localised crustal magnetic fields, the Moon was considered as a passive object when solar wind interacts with it. However, the neutral particle and plasma measurements around the Moon by recent dedicated lunar missions, such as Chandrayaan-1, Kaguya, Chang'E-1, LRO, and ARTEMIS, as well as IBEX have revealed a variety of phenomena around the Moon which results from the interaction with solar wind, such as backscattering of solar wind protons as energetic neutral atoms (ENA) from lunar surface, sputtering of atoms from the lunar surface, formation of a "mini-magnetosphere" around lunar magnetic anomaly regions, as well as several plasma populations around the Moon, including solar wind protons scattered from the lunar surface, from the magnetic anomalies, pick-up ions, protons in lunar wake and more. This paper provides a review of these recent findings and presents the interaction of solar wind with the Moon in a new perspective.
