Water vapor concentration in the lower atmosphere of the Amazon basin within a specific spectral range going from 7.175 to 7.475 μm in the last 5 years. The task should be performed using commercially available satellite imagery. What sensor would you use, which band of this sensor would be the indicated, and what is its spatial resolution?
