v53 v54 110 110 1. [wiki:OMI_observation_modules#obs_p obs_p]: Fill the vector of observations 111 111 1. [wiki:OMI_observation_modules#ocoord_p ocoord_p]: store the coordinates of the observations 112 1. [wiki:OMI_observation_modules#ivar_obs_p ivar_obs_p]: store the inverse error variance of each observation 112 1. [wiki:OMI_observation_modules#ivar_obs_p ivar_obs_p]: store the inverse error variance of each observation for the default mode of OMI, which assumes a diagonal observation error covariance matrix 113 113 1. [wiki:OMI_observation_modules#thisobsid_obs_p thisobs%id_obs_p]: store the indices of state vector elements that correspond to an observation (A single value for observation at grid points, or multiple values for derived quantities or interpolation) 114 114 … … 313 313 === `ivar_obs_p` === 314 314 315 The default mode of PDAF-OMI uses a diagonal observation error covariance matrix **R**. The observation error variances can vary. `ivar_obs_p` is used to specify the inverse observation error variances. 315 316 This should be a vector of real values. It will be used as an argument to `PDAFomi_gather_obs`. The order of the entries has to be consistent in the arrays `thisobs%id_obs_p`, `obs_p`, `ivar_obs_p`, and `ocoord_p`. 316 317
