SECHIBA_QSINT change: standby ticket for further investigations

Reported by: mguimberteau Owned by: somebody
Priority: minor Milestone: Not scheduled yet
Component: Physical processes Version: trunc
Keywords: Cc:


This ticket is created to keep in mind that the SECHIBA_QSINT parameter for offline mode was changed from 0.1 to 0.02 in order to have the same default as in coupled mode. The change has been decided with regard to the low effect when the parameter value is modified in the sensitivity simulations made offline by Vlad:

FG2low2.4964 : forcage CRU-NCEP 2deg, SECHIBA_QSINT comme defaut 0.1
FG2low2.4964.qsint02 : forcage CRU-NCEP 2deg, SECHIBA_QSINT=0.02
FG3WFDEIv1.4964 : forcage WFDEIv1 0.5deg, SECHIBA_QSINT comme defaut 0.1
FG3WFDEIv1.4964.qsint02 : forcage WFDEIv1 0.5deg, SECHIBA_QSINT=0.02

Vlad made plots with the MAPPER for the 4 simulations. See here :

Further investigations could be made because the interception loss and the amount of water reaching the soil depend also on the throughfall_pft parameter activated online and switched-off in offline mode.
So this ticket is not reporting a bug but is a standby ticket to remember this change, apparently having little effect.
