Networking Friday with David Ikpaya

Development of SHACS for Global Atmospheric Carbon-Dioxide Monitoring

On January 20th, 2023, 1-2 PM UTC, David Ikpaya (Nigerian National Space Research and Development Agency – NASRDA) will present his work for the development of a Spatial Heterodyne Atmospheric Carbon-Dioxide Spectrometer (SHACS) for Global Atmospheric Carbon-Dioxide Monitoring.

Finding solutions to the continuous concerns over climate change has been of increased interest in recent times with efforts targeted at mitigating its effects. Satellite observations and in-situ terrestrial networks play key roles in the understanding and management of the problem. Whilst detecting CO2 optically is relatively straightforward, and has been achieved with small satellites, accurate quantitative mapping of CO2 requires very high precision (~1 ppm uncertainty or better) measurements of the gas concentration. This normally requires high-performance, large and complex instruments whose high cost, mass, volume, and power requirements preclude their use on small satellites. In this session, Dr Ikpaya will discuss his clean energy-related research which is focused on the development of SHACS: Spatial Heterodyne Atmospheric Carbon-Dioxide Spectrometer – a robust, no-moving-part, compact precision atmospheric CO¬2 monitoring instrument suitable for both space-based and in-situ based observations. SHACS provides a cost-effective and affordable means of monitoring atmospheric CO2 levels globally. Due to its compact configuration, the instrument fits into a microsatellite-size platform and can provide high-quality hourly measurements of atmospheric CO2 concentration when launched in constellation. His research was published in IEEE Transactions on Geoscience and Remote Sensing journal. This session will also proffer solutions to determining the extent of carbon fluxes in the tropics especially in regions around the equatorial zone due to the sparseness of in-situ CO2 measurement networks. Also, he will present how the SHACS instrument can support policymakers to ensure compliance from all countries as they seek to reduce carbon emissions in response to the global climate crisis. Dr Ikpaya will also highlight the UN Sustainable Development Goals addressed by his research.

This is an Ocean Decade Event.

Dr Ikpaya David Ikpaya is a 2017 Rutherford Fellow and the winner of the 2022 Research Impact Awards Topical Prize. He received his B.Sc. degree in Physics from the University of Calabar, Calabar, Nigeria, in 2000, and his M.Sc. degree in Satellite Engineering and a PhD degree in Remote Sensing Instrumentation from the University of Surrey, Guildford, U.K., in 2008 and 2014, respectively. He participated in the Know-How Technology and Transfer (KHTT) training at Surrey Satellite Technology Limited (SSTL), Surrey, UK for the design, build and launch of NigeriaSat-1 (2001 – 2003), and NigeriaSat-2 & NigeriaSat-X (2006 – 2009). Dr Ikpaya has worked in the Space industry for over 21 years and is the Deputy Director, Ground Station and Mission Control at the National Space Research and Development Agency (NASRDA), Abuja, Nigeria. He is also a Visiting Assistant Professor at the Institute of Space Science and Engineering (ISSE) – an educational arm of NASRDA affiliated with the African University of Science and Technology (AUST), Abuja, Nigeria. His interest is in delivering Earth Observation satellite missions and developing spaceborne optical payload instruments. He has authored and co-authored many scientific articles and is a frequent reviewer of journals for international societies such as SPIE – Society of Photo-Optical Instrumentation Engineers, where is a member. He is also a member of other professional bodies.
