Swarm mission delivers Level 1b (L1b) and Level 2 (L2) data products. These L1b and L2 products include Swarm magnetic field models, ionospheric and thermospheric products, precise orbit solutions including supporting information, etc. The Swarm Product Data Handbook provides  a detailed description and intended to support the use of the L1b and L2 for further processing and/or application. 

Data access

In accordance with ESA Earth Observation (EO) Data Policy, all Swarm L1b and L2 data products are freely available by FTP to ESA-EO registered users. More information on the data access and registration procedure is available on the EO web page:
