Water VaporWater Vapor(read Chapter 6 from Kidder & Vonder Haar)

We will next look at case where is relatively large due to water vapor absorption

Again, the atmosphere (path radiance) dominates

Also the source of path radiance will vary strongly with ,temperature,

and the distribution of water vapor(since water vapor is highly variable vertically and

horizontally)

Now...
