PDAF_OMI_Overview
v21 v22 24 24 25 25 Compared to the classical variant to implement observations with PDAF, OMI is designed to reduce the coding effort for implementing the support for an observation type, its corresponding observation operator, and localization. In particular, only four routines need to be implemented for an observation type: 26 - init_dim_obs27 - obs_op28 - init_dim_obs_l(only for domain-localized filters like LETKF and LESTKF)29 - localize_covar(only needed for the localized EnKF)26 - '''init_dim_obs''' 27 - '''obs_op''' 28 - '''init_dim_obs_l''' (only for domain-localized filters like LETKF and LESTKF) 29 - '''localize_covar''' (only needed for the localized EnKF) 30 30 Here, the first routine reads the observation from file and initializes the information describing the observations. The latter three routines merely call a generi routine provided by PDAF-OMI. 31 31 Other functionality needed during the analyis step bases on variables that are initialized by these routines and is provided by PDAF-OMI.
