Dr Lakshmi Narayanan, Assistant Professor, Environmental Studies, SIAS has received funding for his proposal under the PM Early Career Research Grant scheme, awarded by Anusandhan National Research Foundation (ANRF) — a newly established initiative by the Government of India. The project, titled Early Morning Ionosphere-Thermosphere System (EMITS): Knowledge Gaps and Importance in the Low and Mid-Latitudes, aims to enhance our understanding of the outer reaches of the Earth’s atmosphere during the early morning hours.
As part of the project, a multi-frequency GNSS receiver will be installed on the Krea University campus. This instrument will track signals from navigation satellites such as GPS and NaVIC to study the state of the ionosphere. These radio signals, transmitted in the L and S bands from satellites in medium Earth and geosynchronous orbits, must propagate through the intervening ionosphere before reaching us. By analysing the minor refraction and scattering these signals undergo, researchers can gain valuable insights into the ionosphere. Additionally, archived satellite datasets will be utilised to investigate the early morning upper atmosphere and ionosphere.
The duration of the project is three years, with funding of approximately Rs 60 lakh.
