scaling tests on forcasted neutral density by new solar winds (newBz, etc) algorithem in WAM-IPE #73

Open ZhuxiaoLi66 opened 1 year ago

ZhuxiaoLi66 commented 1 year ago

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). Den_20150316_storm_para3_newBz_ori_msis2_GRACE_orbit_mean300_6lines
