Next up in our ‘Meet the GHRSST Science Team’ series, we are excited to introduce Dr. Marouan Bouali. Dr. Bouali is a Chief Scientific Officer (CSO) and Senior Satellite Remote Sensing R&D Scientist at the start-up, Orbty Ltda., based in São José dos Campos, Brazil.

Educational and Professional Journey

Dr. Marouan Bouali holds an engineering degree in Computer Science from Télécom Physique Strasbourg and a Master’s degree in Signal and Image Processing from the Univeristy of Louis Pasteur in Strasbourg. In 2011, he received his PhD in Signal and Image Processing from élécom ParisTech, Université Paris VI.

Following his PhD, Dr. Bouali joined the NOAA/NEDIS/STAR Sea Surface Temperature team as a Postdoctoral Scientist and then as Research Scientist I where he was affiliated with the Cooperative Institute for Research in the Atmosphere (CIRA). In 2014, he made the move to Brazil where he worked as a Research Scientist at the Satellite Oceanography Laboratory at the Institute of Oceanography at the University of São Paulo (IOUSP) until 2021. Since then, he has been with ORBTY Ltda. Where is he leads and coordinates ORBTY’s R&D activities related to remote sensing of water quality parameters (chlorophyll-a concentration, turbidity) using high-resolution satellite sensors (Sentinel-2 MSI and Landsat 8/9 OLI). He is also responsible for ORBTY’s Multidimensional Dynamic Data Fusion System (M3DFS) which is currently used for the generation of Level 3 meteorological and oceanographic datasets from microwave and infrared instruments.

Research Interests

Within the GHRSST framework, Dr. Marouan Bouali’s research interests include satellite SST gradients (intercomparison and validation with in situ data), cloud detection algorithms, sensor noise correction and computer vision/machine learning methods for the fusion of multi-mission SST datasets. Currently, he is working on new techniques for the generation of Metocean Level 3C/3S/4 products from microwave and infrared satellite instruments.

Journey with GHRSST

Dr. Marouan Bouali first became involved with GHRSST during his tenure at NOAA/NEDIS/STAR. Since the SST Team was highly involved with the GHRSST framework, Dr. Bouali started participating in the GHRSST International Science Meetings. After making the career move to IOUSP in 2014, he continued to be engaged in the community, participating regularly in the GHRSST annual meetings.

Since starting his journey with the GHRSST Community, Dr. Bouali says that GHRSST has allowed him to stay updated on the main scientific challenges associated with the estimation of SST from satellite sensors – both from a user and data provider perspective. Further, GHRSST has provided him with the opportunity to collaborate with scientists across several institutions who are actively involved in GHRSST’s scientific efforts.

For Dr. Marouan Bouali, dedicating an important part of his research activities at NOAA and IOUSP, where he worked on several SST topics including cloud masking, destriping and data fusion, stand out as significant achievements and memorable experiences during this time as a member of the GHRSST Community. Moreover, he was pleased and honoured to be elected as a member of the GHRSST International Science Team in 2018.
