CHAMP and Swarm satellite magnetic data are combined to establish the lithospheric magnetic field over the Tibetan Plateau at satellite altitude by using zonal revised spherical cap harmonic analysis (R-SCHA). These data are integrated with geological structures data to analyze the relationship between magnetic anomaly signals and large-scale geological tectonic over the Tibetan Plateau and to ...

The Chandra Multi-wavelength Project (ChaMP): a serendipitous survey with Chandra archival data. Abstract. The launch of the Chandra X-ray Observatory in July 1999 opened a new era in X-ray astronomy. Its unprecedented, < 0.5 " spatial resolution and low background are providing views of the X-ray sky 10-100 times fainter than previously possible. We have initiated a serendipitous survey (ChaMP...

The High Accuracy Satellite Drag Model (HASDM) is the operational thermospheric density model used by US Space Force Combined Operations Center. By using real-time data assimilation, HASDM can provide estimates with increased accuracy over other empirical models. With historical being released publicly for first time, we analyze to compare dominant modes of variability in upper atmosphere as mo...
