Advances in the Remote Sensing of Solar-Induced Chlorophyll Fluorescence for Vegetation Stress

Dear Colleagues, 

Monitoring and assessing the impacts of biotic and abiotic stress on vegetation holds significant importance for food production and global ecosystem health in the context of climate change. Given its inherent connection to photosynthesis, solar-induced chlorophyll fluorescence (SIF) shows potential as an emerging remote sensing method for identifying plant stress.

Numerous studies have already demonstrated that SIF exhibits a more sensitive response to drought and high-temperature stress than vegetation indices. However, the underlying mechanism of SIF’s response to different types of stress remains unclear. Additionally, the response patterns of SIF at different temporal and spatial scales still lack sufficient understanding. Moreover, further in-depth research is required to explore effective methods for retrieving physiological anomalies caused by stress from SIF and subsequently to develop remote-sensing-based approaches for stress assessment.

We invite research that advances our understanding of SIF’s response to across different scales and various plant types, as well as explores how SIF can be effectively utilized as a stress assessment method.

Topics of interest for this Special Issue include:

• The response of SIF to biotic (such as bacteria, parasites, insects, weeds) and abiotic stress (such as drought, salinity, extreme temperatures) at different spatial and temporal scales.
• Theoretical and experimental advances in understanding the mechanistic relationships between stress-induced physiological variations and SIF.
• The retrieval of stress-induced physiological anomalies from SIF.
• Combining radiative transfer model and vegetation physiological model to simulate SIF signals under stress conditions.
• Stress monitoring and assessment methods based on SIF.
• The impact of stress on the relationship between SIF and gross primary production (GPP).
• Utilizing SIF to evaluate the impacts of stress on crop production and ecosystem health.
