Chlorophyll content in the vegetation: Satellite images can provide information about vegetation indices, such as NDVI (Normalized Difference Vegetation Index), which can be used to estimate the chlorophyll content and overall health of vegetation in a specific location.

Greenhouse gas emissions from rice paddies: Satellite images and remote sensing data can be used to monitor and estimate greenhouse gas emissions, including methane, from rice paddies. This can be done by analyzing the spectral signatures and patterns associated with rice cultivation and its impact on the surrounding environment.

Land surface temperatures: Satellite-based thermal sensors can measure land surface temperatures by detecting the emitted thermal radiation. This information is valuable for monitoring urban heat islands, assessing vegetation health, and studying climate patterns.
