- Similar pattern is seen between the analysis increments for SWE in (1) the 2D-OI and (2) the SEKF.
- Note that large differences are seen in some regions due to inconsistency of snow density between the 2D-OI analysis and trajectory (lower limit of 100kg/m3 in the 2D-OI but 50kg/m3 in the model).
- When SWE from the 2D-OI is assimilated directly in the SEKF (3), such differences are not seen. (The trial branch: dako_CY48R1.1_SEKF_tmp)
- This is not an issue in the future when snow depth observations are assimilated directly in the SEKF
