Results of "Storm Time Data Assimilation in the Thermosphere Ionosphere with TIDA" CHAMP, GRACE-A, and GRACE-B neutral density data assimilation into CTIPe for 2003 Halloween Storms

# README Results for the article "Storm Time Neutral Density Assimilation in the Thermosphere Ionosphere with TIDA". There are three storms presented here: 1. 2003 storm: October 26-30, 2003 2. 2004 storm: July 26-30, 2004 3. 2002 storm: September 27 - October 2, 2002. For each of these three storms, there are four runs. For each storm, we've done a run assimilating all satellites, and then three more assimilating each satellite individually and comparing against the others. Each directory name before underscore identifies the date the run was started. After the underscore identifies the date assimilated. This readme uses the notation that in curly brackets the satellites assimilated are given. - a stands for GRACE-A - b stands for GRACE-B - c stands for CHAMP The runs are summarized below: 1. 2003 storm: {a, b, c}: 2021-12-29T1259_... 3. 2003 storm: {a}:       2022-01-01T1654_... 4. 2003 storm: {b}:       2022-01-02T1423_... 2. 2003 storm: {c}:       2021-12-29T2342_... 5. 2004 storm: {a, b, c}: 2022-01-03T1614_... 6. 2004 storm: {a}:       2022-01-04T1027_... 7. 2004 storm: {b}:       2022-01-04T2144_... 8. 2004 storm: {c}:       2022-01-05T0502_... 9. 2002 storm: {a, b, c}: 2022-01-02T2025_... 10. 2002 storm: {a}:       2022-01-05T1056_... 11. 2002 storm: {b}:       2022-01-05T1854_... 12. 2002 storm: {c}:       2022-01-06T1017_... ## Example result directory 2021-12-29T1259_d2003-10-27 ├── density_champ_density.csv ├── density_grace-a_density.csv ├── density_grace-b_density.csv └── inputs     ├── reference_2003-10-27_input.txt         └── special_2003-10-27_input.txt                  1 directory, 5 files ## Zenodo doesn't support directories So, the file structure has been flattened in the following way: Before: ./aaa/bbb/ccc.png After: ./aaa-bbb-ccc.png https://unix.stackexchange.com/~/45659

Results of "Ensemble Kalman Filter for the Thermosphere Ionosphere", CHAMP neutral density assimilation into CTIPe for March 20, 2007

These data are the result of assimilating neutral density measurements from the CHAMP satellite on March 20, 2007 into the CTIPe model and and comparison of results with observations made by the GRACE satellite. Data assimilation is performed in three configurations: Configuration (i) is ds, state correction. Configuration (ii) is dfds, both input estimatation and state correction. Configuration (iii) is df, estimation of model inputs only. This data is associated with the following publication: <blockquote> Codrescu S., M.V. Codrescu, and M. Fedrizzi (2018), An Ensemble Kalman Filter for the Thermosphere-Ionosphere, Space Weather, 16, doi:<a href="http://dx.doi.org/10.1002/2017SW001752" title="Link to external resource: 10.1002/2017SW001752">10.1002/2017SW001752</a>. </blockquote>

CHAMP and Swarm solar activity- and height-scaled polar cap plasma density measurements

Solar activity- and height-adjusted plasma density measurements in the polar cap (i.e., above 80° latitude in Modified Apex110 coordinates) from the Swarm and CHAMP satellites. covering the entire CHAMP mission period (2002–2009) and the Swarm mission period from launch through February 2020. Plasma density measurements are scaled to a nominal solar activity level of <F10.7>27 = 80 sfu, and an altitude of 500 km, as described in Hatch et al.

Observations of low-latitude traveling ionospheric disturbances by a 630-nm airglow imager and the CHAMP satellite over Indonesia

We report the first comparison of ground and satellite measurements of low-latitude traveling ionospheric disturbances (TIDs). Three TID events were simultaneously observed by a 630-nm airglow imager and the CHAMP satellite on April 30, 2006 (event 1), September 28, 2006 (event 2), and April 12, 2004 (event 3) at Kototabang, Indonesia (geographic coordinates: 0.2$^\circ$S, 100.3$^\circ$E, geomagnetic latitude: 10.6$^\circ$S). In 630-nm airglow images of all three events, there are clear southward-moving structures. Events 1 and 2 are a single pulse with horizontal scales of $\sim$500--1000 km.  Event 3 shows five wave fronts with a horizontal scale size of 500--1000 km. All three TIDs are medium-scale TIDs. Horizontal wavelengths of both airglow intensity at an average emission altitude of 250 km and CHAMP neutral density variations measured at 400 km are estimated by fitting a sinusoidal function to the observed data. For events 1 and 3, estimated horizontal wavelengths are nearly equal, indicating both instruments are observing the same wave.   For event 1, the CHAMP electron density mapped along the geomagnetic field line onto the airglow altitude does not show wave structure similar to the airglow variation. For events 2 and 3, the relationship of electron density and airglow intensity is unclear. These results suggest that the cause of the observed TID is not caused by ionospheric plasma instability but by gravity waves in the thermosphere. According to these results, we conclude that the observed TIDs in all three cases are caused by gravity waves in the thermosphere.
