    v19 v20  
    3636The work on the new driver has been picked up since July 2020 by X. W. A short report summarizes the first part of this efforts and can be found on https://forge.ipsl.jussieu.fr/orchidee/attachment/wiki/Documentation/Forcings/nouveau_driver_doc.2.pdf.

    4040* the recent version of new driver is included in the trunk. This is committed in r7082. 
     
    4848* In spring 2021, Matt mentioned the speed of simulation by using the new driver, compared to the old one. Some profiling tests were applied to the simulations by using new and old drivers. In PARAM/run.def dt_sechiba =1200 is responsible for most of the slowness of the new driver. The value of this parameter depends on user's need. The smaller, the slower, with higher-resolution of time steps in the simulation. 
    4949* In summer 2021, a new ticket http://forge.ipsl.jussieu.fr/orchidee/ticket/786 was submitted concerning a problem of the new driver when using the compressed forcing file. By using the latest version of compressed forcing file CRU JRA v2.2, small modification were applied and tested. The new driver now works with the compressed forcing file such as CRU JRA 0.5 degree. But the new driver does not work with the older version of CRU JRA v2.1 0.5 degree due to some inconsistency between land variable and contfrac.  
     50* In summer 2021, the new driver in Tag 2.2 is updated by Agnes.
