+ +Grid structure used in the MPAS/DART interface +The MPAS/DART interface is +built on MPAS's unstructured centroidal Voronoi mesh, +and does not regrid to latitude-longitude grids. In MPAS, the finite-volume +approach based on a C-grid staggering retains prognostic equations for mass +at the center of finite-volume cells and for the normal component of velocity +(u) at the faces (or edges in 2D) of the cells. +The normal component of velocity (u) at cell edges is then used to +reconstruct zonal and meridional winds at cell centers (V) + using radial basis functions (RBFs). +To avoid the singularity issue on the poles, the cartesian coordinate is employed. + +The forward operators on the unstructured grid mesh are constructed as follows. +The dual of the Voronoi mesh, or the triangular mesh (shown as dashed lines in the +figure), is used to search the closest cell center to an arbitrary (or observation) +point, then find three cell centers of the triangle enclosing the desired point. +Mass fields are then horizontally interpolated from the cell centers to the observation +location using a barycentric (e.g., area-weighted) interpolation. +
+ +While the observed wind quantities are zonal and meridional winds, the normal +component of velocity (u) is the only prognostic wind variable in MPAS, +we thus implement a couple of different ways of assimilating wind observations. +The options determine which wind variables are used in the forward operator to +compute expected observation values; how the horizontal interpolation is computed +in that forward operator; and how the assimilation increments are applied to update +the wind quantities in the state vector of the analysis. + +Preliminary results based on real data assimilation experiments indicate that +performance is better when the zonal and meridional winds are used as input to the +forward operator that uses Barycentric interpolation and the prognostic u +wind is incrementally updated. However, there remain scientific questions about +how best to handle the wind fields under different situations. For the details +on the wind data strategy, refer to the +documentation in DART. + +For any questions or future collaboration, please contact either +Soyoung Ha (syha@ucar.edu) or the DART team (dart@ucar.edu) + + ----- @@ -191,7 +276,7 @@ Alexis Zubrow, azubrow@unc.edu - + ----- @@ -233,7 +318,7 @@ Alexis Zubrow, azubrow@unc.edu - + -----
