Comparison between Local Ensemble Transform Kalman Filter and PSAS in the NASA finite volume GCM–perfect model experiments
Local Ensemble Transform Kalman Filter PSAS NASA finite volume GCM–perfect model
2009/11/2
This paper compares the performance of the Local Ensemble Transform Kalman Filter (LETKF) with the Physical-Space Statistical Analysis System (PSAS) under a perfect model scenario. PSAS is a 3D-Var as...
