Johan Mellqvist

Johan Mellqvist is a Full Professor in Geoscience and Remote Sensing at Chalmers University of Technology in Sweden. His work focuses on optical remote sensing methods for environmental monitoring, with particular expertise in measuring emissions from various sources.

His research spans several critical environmental domains:

• Development of spectroscopic optical methods for environmental data collection
• Mapping and quantifying fugitive emissions from industries, agriculture, and water treatment
• Monitoring ship emissions and compliance with international regulations
• Measuring diffuse emissions of hydrocarbons (VOCs)
• Working with European standardization (CEN) on emission measurement protocols

Professor Mellqvist's research has significant implications for climate change and air quality management. His work demonstrates consistent focus on methane emissions across multiple environments (lakes, coastal areas, industrial sites) and ship emissions monitoring. His recent publications show increasing attention to regulatory compliance and real-world measurement validation, reflecting the practical application of his research.

His research is supported by multiple funding agencies including the Swedish Transport Administration, Swedish National Space Board, VINNOVA, and the European Commission. This diverse funding portfolio indicates the broad relevance of his work across academic, governmental, and regulatory domains.

Professor Mellqvist leads or participates in numerous research projects focused on emissions monitoring, with particular emphasis on developing and validating measurement techniques that can be used for regulatory compliance. His work bridges the gap between scientific measurement and practical environmental policy implementation.
