Welcome to the GEOSadas wiki!

The easiest why to set up an ADAS experiment is to use an existing experiment template. Such templates are available here. In the initial release of the ADAS v5.27.1_p3 the following experiment templates are available:

C48f.input - C48 3DVAR C90C.input - C90 3DVAR C90C_replay.input - C90 hybrid 4DEnVar, with ensemble replayed to the from FP C90C_ens.input - C90 hybrid 4DEnVar x0043.input - C360 hybrid 4DEnVar; template for actual official x0043 x-test experiment x0044.input - C360 hybrid 4DEnVar; template for actual official x0044 x-test experiment prePP.input - full resolution, FP-like, Hybrid 4DEnVar The user should copy a template of interest, make minor editing to adjust userID and location of experiment home (referred to as FVHOME), and then use the program runjob to process the template, e.g.,

FULLPATH/GEOSadas/install/bin/runjob -l path_of_user_adjusted_template_.input

where FULLPATH is the remainder of the path to the GEOSadas bin directory.

The existing experiment templates can be adjusted for setting experiments for a time period other than those set in the template, and the observing system can also easily be edited to accommodate users need.

The more experienced users can run the base GEOSadas script, namely fvsetup, by hand.

Typically, runjob will prompt the user asking whether to submit the main job to the batch system. In case the user chooses to postpone batch submission, this can be done at a later time by

cd FVHOME/run sbatch g5das.j

Note that in the particular case of x-experiment templates, the main job scripts are named according to the experiment number, e.g., x0043 as x43.j, for its main job (i.e., replace g5das.j above with x43.j).
