| 160 | Since the update of the 11-layer hydrological scheme into the trunk of ORCHIDEE in 2012, a strong positive bias on latent heat flux has been diagnosed with the 11-layer scheme at winter time for deciduous species compared to observations and compared to the 2-layer scheme. The figure below shows how the seasonal variations of the latent heat flux simulated with the 2-layer scheme and the 11-layer scheme compare to observations for different PFTs: |
