To my recollection, we were leaning toward using user-specified grid exclusively. Since then, this issue has been largely buried under more urgent issues (this has never been a high priority issue except in the first couple of years, i.e., initial development by Cam/Peter and early stage of my involvement after peter left). There were some reasons for using user-specified grid (also to my recollection):
(1) The model-grid reference sometimes gave problem for multi-model evaluation because of truncation of latitude/longitude values in the netCDF file. This made the long/lat values inconsistent for different models. In addition, if unprocessed model outputs (i.e., individual models' own native grid), the model-referenced system have to accompany another option "choose the reference model data for defining domain". (2) The obs-grid reference was planned to be included, but had very low priority because we (Peter/Cam/myself) didn't see any immediate case to use (it's been a placeholder since the beginning). As the code moves to use multiple observations, this has become largely forgotten. (3) With the planned user-specified domain in the UI version, having users to specify their own analysis grid may be most useful. ----------------------------------------------------------------- Jinwon Kim Joint Institute for Regional Earth System Science and Engineering and Dept.
