ADAS Analyses Applied to VTMX
v1 km
horizontal resolution incorporating all available observations collected
during IOPs
vAnalysis =
Background + Correction
v = RUC-2 + S weight x (observation – background)
vBiases:
vSurface observations on slopes/peaks affecting free atmosphere
above valleys. Developed “terrain weighting factor”
vAnalyses too
smooth in horizontal and vertical. Reduced horizontal and vertical
radii of influence
vSurface
observations from adjacent valleys affecting analysis. Developing “anisotropy
weighting factor”
vMass/wind fields not constrained to be dynamically consistent. Developing variational
constraint on wind field
