on production of gamma rays and relativistic runaway electron avalanches from martian Dust Storms
Geophysical Research Letters, 2017Co-Authors: S Arabshahi, Walid A Majid, J R Dwyer, H K RassoulAbstract:Production of runaway electron avalanches and gamma rays originating inside Martian Dust Storms are studied using Monte Carlo simulations. In the absence of in-situ measurements, we use theoretical predictions of electric fields inside Dust Storms. Electrons are produced through the Relativistic Runaway Electron Avalanches (RREA) process, and energetic photons are results of the bremsstrahlung scattering of the electrons with the air. Characteristic lengths of the runaway electron avalanche for different electric fields and the energy spectrum of electrons are derived and compared to their terrestrial counterparts. It is found that it is possible for Martian Dust Storms to develop energetic electron avalanches and produce large fluxes of gamma ray photons similar to Terrestrial Gamma ray Flashes (TGFs) from Earth's thunderStorms. The phenomenon could be called Martian Gamma ray Flash (MGF), and due to the very thin atmosphere on Mars, it can be observed by both ground-based instruments or satellites orbiting the planet.

enhancement of oceanic parameters associated with Dust Storms using satellite data
Journal of Geophysical Research, 2008Co-Authors: Ramesh P Singh, Anup K Prasad, Vinay K Kayetha, Menas KafatosAbstract:over the Arabian Sea causes chlorophyll blooming (usually 10–22.43 mg/m 3 ) within a period of 1–2 to up to 3–4 days. However, we have also found significant anomalous cooling of the ocean surface (SST) and relatively higher ocean wind speeds (QuikSCAT) during Dust Storms that may lead to favorable conditions for blooming. Exact nature and cause of chlorophyll bloom in the semienclosed northern Arabian Sea, surrounded by one of the world’s major sources of Dust Storms (Africa, Middle East, Iran, and Afghanistan), are very important in understanding the productivity and the biogeochemical cycles of the marine ecosystem. The results have been validated using the Indian Remote Sensing Polar-4 Ocean Color Monitor (IRS P4 OCM) data.
