scaling tests on forcasted neutral density by new solar winds (newBz, etc) algorithem in WAM-IPE

[ZhuxiaoLi66]

The new solar-wind deriving algorithm from Kp in WAM-IPE has been verified to improve the neutral density forecast largely against the old algorithm, especially during storm time. While it is still lower than the WAM-IPE results with the observational solar winds input. we plan to do more investigation on the simulation results and do the comparison to check the possibility and rationality to scale the forecasted neutral density by the new algorithm.

The following plot is the neutral density comparisons along GRACE orbits within several settings & versions of WAM-IPE for 2015 St. Patrick storm case, which indicates the validation of the new algorithm (newBz).

The followings are the 3hrly 2D neutral density maps during the 20150316-0319 storm time from the newBz run and obs-input
run.

The followings are the 3hrly 2D neutral density maps during the 20150316-0319 storm time from the newBz run and obs-input
run, the corresponding mean and standard deviation values of the maps are shown on the right top of each map.
