    3333The EnKF implemented in PDAF follows the original EnKF by Evensen (1994) including the correction for perturbed observations (Burgers et al. 1998). The EnKF implemented in PDAF is reviewed by Nerger et al (2005) and described in more detail by Nerger (2004). (See the [PublicationsandPresentations page on publications and presentations] for publications and presenations involving and about PDAF)

    35 There is no localized variant of the EnKF in PDAF. In our studies (Nerger et al. 2005, Neger et al. 2007), the EnKF showed deficiencies compared to the SEIK filter performed. Due to this, we focused more on the SEIK filter and the ETKF after these comparison studies. For real applications, we generally recommend using SEIK or ETKF, or their local variants LSEIK or LETKF.
