Dr. Salinas is an Assistant Research Scientist at NASA Goddard Space Flight Center. He works with NASA GSFC through the Goddard Earth Sciences Technology and Research 2 (GESTAR-2) program under University of Maryland, Baltimore County. He did his PhD in Earth Systems Science under the Taiwan International Graduate Program - Earth Systems Science, a program under both the National Central University (NCU) and the Academia Sinica in Taiwan. For his PhD, he did research under the tutelage of Prof. Loren Chang from the NCU Department of Space Science and Engineering as well as under Prof. Danie Mao-chang Liang from the Academia Sinica Institute of Earth Sciences. His research focused on using satellite observations of upper atmospheric carbon dioxide and first-principles Physics-based whole atmosphere models to further our understanding on wave-mean flow dynamics and atmosphere-ionosphere coupling. After finishing his PhD in 2019, he continued on as a post-doc with Prof. Chang and expanded his research by also using other tracers such as upper atmospheric atomic oxygen, water vapor and carbon monoxide to further our understanding of upper atmospheric physics and chemistry. Throughout his PhD and post-doc researches, he has had the privilege to work with and, more importantly, learn from numerous senior scientists from NASA and NCAR High Altitude Observatory. At NASA, he will continue his researches on the physics and chemistry involved in atmosphere-ionosphere coupling under Dr. Dong L Wu while also expanding his reach by helping out NASA spacecraft missions accomplish their science goals.

Brief Bio
Current Projects
(1) Investigation of Global Ionospheric Conductivity Variabilities driven by E-region electron density
Earth's Ionosphere
This work aims to address issues and uncertainties in global estimates of ionospheric conductivity by using the first global and multi-decade satellite-based observations of E-region electron density (Ne). We propose answering the following questions: (a) How much does the uncertainties in E-region Ne variability contribute to ionospheric conductivity? (b) What is the satellite-observed and modeled latitude-local time profiles of E-region Ne as a function of longitude, altitude, season, and solar cycle. (c) How consistent are the satellite-derived E-region Ne variabilities with those observed by ground-based instruments such as ionosondes and radar?
FUNDING ACKNOWLEDGEMENT
Dr. Salinas is Principal Investigator of a NASA grant supporting this project. The grant is provided by the NASA Living With A Star Program. The project duration is between June 2024 and June 2028.
(2) Space Weather Effects on Ionospheric E-region Electron Density as observed by Global Navigation Satellite System Radio Occultation Missions
Earth's Ionosphere
This work aims to determine E-region electron density’s response to the geomagnetic storms. This will be done by analyzing and quantifying the dependencies of E-region Ne on geomagnetic indices as observed by past and current GNSS RO measurements. Comparisons will be made with ground-based instruments such as ionosondes and radar as well as with first principles Physics-based models.
FUNDING ACKNOWLEDGEMENT
Dr. Salinas is Principal Investigator of a grant supporting this project. The grant is provided by the University of Maryland Baltimore County through Strategic Awards for Research Transitions (START) program. The project duration is between June 2024 and June 2025.
(3) Development of the E-region Prompt Radio Occultation Based Electron Density (E-PROBED) Model.
Earth's Ionosphere
This project aims to develop an empirical model of the ionospheric E-region electron density (Ne) using Global Navigation Satellite System Radio Occultation (GNSS RO) measurements. The model is called E-region Prompt Radio Occultation Based Electron Density (E-PROBED) model and it will account for E-region Ne variabilities driven by solar, geomagnetic and lower atmospheric forcing. It shall be developed for scientific and space weather operational use.
