| | 25 | - Yuan summarized his approach with a few [attachment:Yuan20201127_diffuse_radiation.pptx slides] |
| | 26 | - We discuss the differences between Yuan approach and the current 2 streams RT scheme in the Trunk |
| | 27 | - Yuan scheme assume no reflection of light at the background which simplifies the overall computation |
| | 28 | - 2stream scheme also computes the diffuse and direct fraction at each layer but do not valorise for the photosynthesis; while Yuan compute two times the photosynthesis (for sunlit and shaded leaves) |
| | 29 | - In principle all the 2stream scheme could be use to compute like Yuan the sunlit and shaded photosynthesis |
| | 30 | - In addition Yuan model include a detailed computation of the fraction of incoming direct vs diffuse light depending on atmospheric conditions |
| | 31 | - Juliette explained that the implementation for BVOCs is similar to Yuan approach (based on Spitters pappers); The scheme also compute the incoming direct vs diffuse light but with a different approach than in Yuan. |
