Surfex v8_0 was built by developers, so documentation is available by contribution.
As it’s not easy to extract from this sort of documentation a wanted information, for next version, a summary will be done here of the documentation provided by developers.
1. Draft of the schedule for the building of SURFEX V8
Contains:
2 main parts: Automatic scripts (with a manual part) are used to transform the SURFEX code to suppress global variables. So that these scripts are able to run on the SURFEX code, some "normalizations" need to be performed.
=> These normalizations constitute the first part of the (...)

Suggested changes for cy40t1 Rimvydas Jasinkas, LHMI, Ulf Andrae SMHI 2013-09-24(extract)
Updated 2014-03-17 (point 8) Introduction The latest version of the code for HARMONIE based on the CY40 version of the IFS/ARPEGE code has gone through a first sanity check on some basic (...)
Contains: modifications for Mesonh compilation in REAL*4 (13 files modified): => problem with tuning of threshold value depending of the level of precision set. In REAL*4, some calculations didn’t achieve, because values were too low. For example in coare30_flux.F90: PRESA(:)=1./ZAC(:) that (...)
Contains: extraction of the Cd drag coefficient from SURFEX to be added in the interface of ARO_GROUND_DIAG. Only 3 SURFEX routines are concerned. The aim is to improve the interface with ALARO.
This contribution is ready and was tested in operational mode with ALARO+SURFEX.
R. Hamdi will (...)

Surfex modification: stochastic surface perturbations (cycle cy38t1op1 - F.Bouttier Oct 2013) Purpose: implement stochastic surface perturbations for ensemble prediction. This code will be used in the MF AROME ensemble prediction system. Description: initial perturbation of surface (...)
