Satellite images and remote sensing data are critical for monitoring and measuring various environmental parameters across specific locations. Specifically, they enable the assessment of chlorophyll content in vegetation through the analysis of spectral reflectance, which helps in understanding plant health. Additionally, advanced remote sensing techniques can estimate greenhouse gas emissions, such as methane from rice paddies, based on changes in land cover and water levels. Lastly, satellites provide vital data for determining land surface temperatures, facilitating climate studies and agricultural monitoring. Therefore, all three measurements listed leverage the capabilities of satellite imagery, making the option "1, 2 and 3" correct.
