New Swarm Ion Temperature Estimation (SITE) data product released
16 Jul 2021
A new dataset of Swarm Ion Temperature Estimation (SITE) is now available for the three Swarm spacecraft.
The primary data products consist of an ion temperature in the upper ionosphere along the orbits of three Swarm satellites. The 2 Hz data are derived using a physics-based data-driven model, which combines an ion heat equation in the ionosphere, Swarm EFI measurements and empirical models. The estimated ion temperature agrees well with independent measurements made by incoherent scatter radars and presents a reliable baseline ion temperature proxy for conditions applicable to the ion energy balance when local heating and cooling processes dominate. The dataset also contains 2 Hz corrected Swarm LP electron temperature and NRLMSISE-00 neutral temperature along the Swarm paths.
The dataset is available on the Swarm dissemination server at the following path:
The dataset covers the time interval from the start of the mission through to 13 November 2020.
