蝌蚪直播

Scientists from 蝌蚪直播's ISR joined thousands of other space- and geo-physicists at last week's 100th meeting of the American Geophysics Union (AGU), showing their work in a set of talks and posters.

Recent PhD Dev Joshi (蝌蚪直播/ISR) presented results聽 on ionospheric irregularities, work which he did with Keith Groves (蝌蚪直播/ISR), John Retterer (蝌蚪直播/ISR), Patrick Roddy (AFRL), and Chaosong Huang (AFRL).

Congrats to Andrew Akala of U. Lagos for receiving the the Africa Award for Research Excellence in Space Science.

蝌蚪直播/ISR space scientists Charlie Carrano, Keith Groves, and Bill McNeil, with their colleague E. Robert Kursinski of PlanetiQ, are simulating ionospheric scintillation in order to better understand its effects on space weather forecasting. Their poster is available here.

ISR's Keith Groves and his team are investigating the impact of magnetic storms on GPS and similar navigation systems.

Solar physicists Ian Hewins (蝌蚪直播/ISR, NCAR/HAO), Dave Webb (蝌蚪直播/ISR), Sarah Gibson (NCAR/HAO), Robert McFadden (蝌蚪直播/ISR, NCAR/HAO), and Barbara Emery (蝌蚪直播/ISR, NCAR/HAO) are using the historic solar maps from the McIntosh archive to investigate solar magnetic features across multiple solar cycles. Their poster is available here.

蝌蚪直播/ISR researchers Rezy Pradipta and Pat Doherty are studying equatorial plasma bubbles ans spread-F. Their poster can be found at at the ESSOAr repository, doi:

Pat Doherty, Director of 蝌蚪直播's Institute for Scientific Research, visits the South African National Space Agency. Her hosts were John Bosco Habarulema (far left) and Zama Katamzi-Joseph (far right). Also visiting SANSA was Sharafat Gadimova (2nd from right) from the UN Office of Outer Space Affairs.

While at SANSA, Pat Doherty meets with Lee-Ann McKinnell, Managing Director of the Space Weather Regional Warning Centre.

As part of her visit, Pat presented a talk to the public on solar storms and their effects on technology such as power grids and communication systems.

Pat and Sharafat had time to visit beautiful Walker's Bay before heading to the 聽64^th聽Annual Conference聽of the South African Institute of Physics (SAIP).

The Workshop on Ionospheric Forecasting for GNSS Operations in Developing Countries: Findings and Challenges took place in Trieste, Italy 27-31 May, 2019. The workshop was co-sponsored by 蝌蚪直播's ISR and organized by ISR Director Pat Doherty and ICTP's Sandro Radicelli and Bruno Nava.

ISR's Keith Groves delivers a lecture on Ionospheric Irregularities and Scintillation. He also chaired the science session on Thursday afternoon.

蝌蚪直播/ISR's Shaun Ard, John Williamson, and Tom Miller (left to right) are part of the Plasma Chemistry Lab at AFRL in Albuquerque, NM. The group is extremely prolific, typically publishing 10-15 research papers in referred journals each year.

The Plasma Chemistry Laboratory receives the 2019-2021 AFOSR STAR Team Award, recognizing the team's "Excellence in Basic Research in Plasma Chemistry for Air Force Systems".聽 Pictured at the award ceremony on Sep. 24, 2019, from left to right:聽Thomas M. Miller (蝌蚪直播/ISR), Col. Eric J. Felt (Director of the Space Vehicles Directorate of AFRL), Nicholas S. Shuman (AFRL), Shaun G. Ard (蝌蚪直播/ISR), John S. Williamson (蝌蚪直播/ISR), Brendan C. Sweeny (NRC postdoc), and Albert A. Viggiano (AFRL).聽Not present: David M. McDonald (NRC postdoc).

The High Temperature Flowing-Afterglow Langmuir Probe (HT-FALP) operates between 100 and 1800 K, reaching temperatures higher than any other probe in operation.

The HT-FALP at 1600 K. The lab studies fundamental chemical interactions involving charged species, which greatly influence atmospheric plasmas such as the ionosphere and impact RF communications.

Researchers at Boston College's ISR measured the temperature dependence of the MnO⁺聽+ H₂/D₂聽reactions between 150 and 600 K using a Selected-Ion Flow Tube (SIFT) apparatus. Details can be found in their article in the International Journal of Mass Spectrometry at

Tom Miller (behind, standing) and John Williamson (in front) have over 30 years of experience in the Plasma Chemistry Lab and its predecessors.
