The versions of the radiation pressure models were used as follows:

----------------------------
CHAMP_2022.zip
GRACE_2022.zip
GRACE-FO_2022.zip
----------------------------

These models were used by Siemes et al. (2023) New thermosphere neutral mass density and crosswind datasets from CHAMP, GRACE, and GRACE-FO. J. Space Weather Space Clim. 13, 16. https://doi.org/10.1051/swsc/2023014
The density data files
- CH_DNS_ACC_*_v02.zip
- GA_DNS_ACC_*_v02.zip
- GB_DNS_ACC_*_v02.zip
- GC_DNS_ACC_*_v02.zip
were generated with this model.


----------------------------
GRACE-FO_2023.zip
----------------------------

This model was used by Hładczuk et al. (2024) GRACE-FO radiation pressure modelling for accurate density and crosswind retrieval. Advances in Space Research, 73(5):2355-2373. https://doi.org/10.1016/j.asr.2023.12.059.
It represents improved knowledge over the previous radiation pressure model GRACE-FO_2022.zip. The density data files GC_DNS_ACC_*_v02b.zip were generated with this model.

GRACE-FO_2024.zip
----------------------------

In 2024, we recalibrated the entire accelerometer dataset. The calibration was improved by updating gravity field models and data collected during high solar activity. The recalibration lead to a slightly different (few percent) scale factor. The change in the scale factor necessitated an update of the radiation pressure model. This model has been generated with the approach by Hładczuk et al. (2024) with the recalibrated accelerometer dataset as input. The density data files GC_DNS_ACC_*_v02c.zip were generated with this model.
