20100405-07 storm validation against GOCE, GRACE and CHAMP satellite observation

[ZhuxiaoLi66]

The storm happened during Apr.5-7 in 2010 has been chosen to be verified against the satellites observation since we have got all GOCE, GRACE and CHAMP neutral number density data during its period. The neutral total number density from former version of WAM compared with the 3 Satellites data, the results is quite different from the other two storm (2013 and 2015 St. Pratrick). The further investigation is performing and the output from the current 'merge' version will applied for the comparison later.

Got it, thanks, Naomi!

After applied the factors to the satellite data, the number density of WAM at quite time in Apr5-7 of 2010 case are consistent to the satellite observation, while the recover from the storm seems much slower compared with the observation. since this doesn't happen for St. Pratrick storm of 2013 and 2015. we are checking the input parameters and other aspects of the run to narrow down the reason.

The following is Mariangel's original data and Adam's input before avgerage and delay.

Tim think one possibility is that this is related to the NO cooling in WAM. it seems TIEGCM driven by AMIE has the same issue with overestimation of density in the latter part of the event. From the following plot, we also can see the event did sustained over the date of Apr.6.
