The Global Aerosol Climatology Project data product based on analyses of channel 1 and 2 AVHRR radiances shows significant regional changes in the retrieved optical thickness of tropospheric aerosols which had occurred between the volcano-free periods 1988-91 and 2002-05. These trends appear to be generally plausible, are consistent with extensive sets of long-term ground-based observations thr...

Ulloa's complete print of the glories and fogbows on Mt. Pambamarca in Peru (now Ecuador) is presented. It shows two other phenomena, an erupting volcano and an as yet unidentified optical effect. The glories and fogbow are analyzed to obtain the drop size of the fog, and the unidentified features are discussed.

Arecibo high-resolution radar images of the southern hemisphere of Venus extending to 78 degrees S show that the surface of the Themis-Alpha-Lada region is characterized by linear deformation zones with volcanoes and corona-like features and by regional volcanic deposits (primarily plains, small shields, and large edifices). Large-scale areal deformation is limited to the tessera of Alpha Regio...

In this paper the investigation results of thermal springs of the Mutnovsky Volcano (Kamchatka, Russia) are provided. Mud pots in the Donnoe Field of this volcano have a unique solution composition. High concentrations of a wide spectrum of chemical elements such as Al, Ti, V, Cr, Ni, Co, REE and PGE were discovered there. To explain the mechanisms of solution formation it was made an attempt t...

This research aims to assess contamination status of water and sediment in Sabalan dam reservoir (SDR) evaluate the impact withdrawal depths on carcinogenic non-carcinogenic risks metals for exposed people. Results metal pollution indices revealed some degree reservoir, especially associated with arsenic. Risk assessment SDR materials through different scenarios depth that consuming from 10 m c...

We present a full-wave analysis method on the transmission of a Gaussian light pulse through a spherical invisibility cloak with causal dispersions. The spatial energy distribution of the Gaussian light pulse is distorted after the transmission. A volcano-shaped spatial time-delay distribution of the transmitted light pulse is demonstrated as a concrete example in our physical model. Both the t...
