Radiosonde vs. temperature sounding. OC3522 - Remote Sensing of the Atmosphere and Ocean - Summer 2001. Water Vapor (read Chapter 6 from Kidder & Vonder Haar). If t d ( l ) is not 0. We will next look at case where d is relatively large due to water vapor absorption

If td(l) is not 0 • We will next look at case where d is relatively large due to water vapor absorption • Again, the atmosphere (path radiance) dominates • Also the source of path radiance will vary stronglywithl ,temperature, and the distribution of water vapor(since water vapor is highly variable vertically and horizontally) • Now... water vapor information Known temperature distribution and
