WebWe evaluate performance of the Catchment Land Surface Model (CLSM) under flood conditions after the assimilation of observations of the terrestrial water storage anomaly (TWSA) from NASA’s Gravity Recovery and Climate Experiment (GRACE). Assimilation offers three key benefits for the viability of GRACE observations to operational … WebData assimilation is a powerful and widely used computational technique that has many application areas throughout mathematics and science. At a very high level, data assimilation refers to the process of merging prior forecasts with new observations , creating a new analysis that is an “optimal” blending of the two by taking into account ...
WebCorrespondingly, the background fields (without data assimilation) were generated from a 24-h forecast initialized by the NCEP FNL analysis data, 12 h prior to the time of analysis. Then, we took the 24-h integration as the control run (referred to as CTRL) to prepare the basic states for assimilation and to assess the results.
