DESCRIPTION:Speakers: B Hari Haran (TIFR)\n\nA multi-disciplinary research
  vision is proposed to push the boundaries of high-energy atmospheric phys
 ics and solar-terrestrial interactions using the GRAPES-3 experiment\, and
  large-scale scientific computing. A broadband capability for probing thun
 derstorm electrodynamics will be established by synthesizing observations 
 of GeV-scale muon acceleration with Relativistic Runaway Electron Avalanch
 es and low-energy Thunderstorm Ground Enhancements\, which preliminary 202
 6 data indicate event record at three times the rate of thunderstorm-induc
 ed muon events. Simultaneously\, space weather prediction and solar plasma
  dynamics will be advanced by correlating GRAPES-3 cosmic-ray intensity va
 riations with interplanetary scintillation observations. To realize these 
 physical objectives across the Nilgiris (≈1000 km^2)\, the instrumentati
 on array will be expanded through a regional electric field mill (EFM) net
 work\, a radio antenna array to extend cosmic-ray sensitivity past the "kn
 ee" (>10^15 eV)\, and a dedicated 3-axis magnetic field sensor at Gauribid
 anur. To execute these high-volume multi-messenger analysis workloads and 
 other disciplines\, a scalable\, distributed high-throughput computing (HT
 C) facility modeled on the Open Science Grid and Center for High Throughpu
 t Computing at UW-Madison will be constructed.\n\nhttps://scitalks.tifr.re
