Discussion Overview
The discussion revolves around the definition, meaning, and applications of the lidar s-function, specifically the equation S(r)=ln(P(r)r^2/(P(r0)r0^2)). Participants explore its significance in atmospheric research and its relation to light intensity and distance.
Discussion Character
- Exploratory, Technical explanation, Homework-related
Main Points Raised
- One participant defines the s-function and its components, indicating that r represents distance in the atmosphere and P denotes the intensity of detected light.
- Another participant expresses frustration at the lack of explanations regarding the s-function and seeks recommendations for literature on lidar and atmospheric research.
- A different participant references ERIM's Electro-Optic handbook, suggesting that the equation may relate to propagation loss and the spread of a Gaussian beam, but notes that the specific equation is not found in the book.
- One participant mentions conducting research for school and indicates that several papers contain the same equation and graphs, but they lack clarity on the rationale behind its specific form, hypothesizing it relates to atmospheric attenuation.
Areas of Agreement / Disagreement
Participants do not reach a consensus on the explanation or origin of the s-function equation, and multiple viewpoints regarding its interpretation and application remain present.
Contextual Notes
Some assumptions about the equation's derivation and its application in atmospheric contexts are not fully explored, and there is a lack of clarity on the specific sources of the equation.
