SET HASDM Density Database

SET has extracted two solar cycles of thermosphere density data to create the SET HASDM density database. Because of its accuracy, time resolution, global scale, and information content the SET HASDM database densities are suitable for use as a new space weather benchmark for atmospheric expansion against which space weather events are measured. The SET HASDM density database now resides in a SQL database with open community access for scientific studies.

Database Portal

The information in the SQL-based SET HASDM Density Database is available from January 1, 2000 through December 31, 2019. Data records exist every 3 hours during solar cycles 23 and 24. The database has a grid size of 10° latitude × 15° longitude with 25 km altitude steps between 175–825 km.

HASDM ML

The statistical metrics in the SET HASDM Density Database are characterized by the META-HASDM project between West Virginia University and SET. It uses machine learning (ML) to quantify the database uses many modes of a neural network. Called HASDM ML, it characterizes the global density environment for rapid operational use, for quantification of uncertainty, and for improving ballistic coefficients for all LEO objects.
