checking down the density drop issue in operational runs #84

Open ZhuxiaoLi66 opened 1 year ago

In operational runs, it has been found that the global mean neutral density drops dramatically after the 'current' time.

The free WAM runs with the observed solar wind drivers .vs. with the derived drivers from kp & f107 have been investigated to confirm that whether or not it is related to the input drivers.

The following plots shows the global mean neutral density at 400km with obs solar drivers .vs. with derived solar drivers from kp & f107. which corresponding the case before .vs. after the 'current' time in operational runs. den_obs_derive_kp_kpa_f107_202311 den_obs_derive_kp_kpa_f107_swvel_202311 den_obs_derive_kp_kpa_f107_swbz_202311

We also checked temperature at about 400km (PL140), its change pattern is consistent with the ones of neutral density. Temp_pres_400km_gm_Nov_2018 DEN_400km_global_mean_Nov_2018
