Overview

Barclay Clemesha was affiliated with the National Institute for Space Research in Brazil. Their research work focused primarily on topics related to the ionosphere and magnetosphere dynamics, solar and space plasma dynamics, as well as GNSS positioning and interference. These areas overlapped with the fields of physics and astronomy and aerospace engineering.

The scientist's main subfields of study included:

  • Astronomy and Astrophysics
  • Aerospace Engineering

The research output included publications in peer-reviewed scientific venues, notably the journal Annales Geophysicae. The documented paper published by Barclay Clemesha was:

  • "Diurnal mesospheric tidal winds observed simultaneously by meteor radars in Costa Rica (10° N, 86° W) and Brazil (7° S, 37° W)", published in 2020 in Annales Geophysicae

The scientist collaborated frequently with several coauthors, namely:

  • R. A. Buriti
  • W. K. Hocking
  • P. P. Batista
  • Igo Paulino
  • Ana Roberta Paulino

The combination of topics explored in Barclay Clemesha's work spanned atmospheric and space phenomena related to geomagnetic and plasma environments, with a particular focus on mesospheric tidal winds and their interactions with space weather conditions. The use of meteor radar observations in diverse geographic locations exemplified their approach to studying atmospheric dynamics across hemispheres.
