We inform the Swarm user community that a new dataset, generated in the frame of Swarm-TIRO (Topside Ionosphere Radio Observations from multiple LEO-missions) project has now been made available.
The Swarm-TIRO project provides two groups of products for several satellite missions: Total Electron Content (TEC) and electron density (NE).
The topside TEC product is derived from the dual-frequency Global Positioning System (GPS) observations and provided for the CHAMP, GRACE and GRACE-FO missions.
The electron density product is derived from the dual-frequency measurements obtained from the inter-satellite K-Band ranging (KBR) system between the two GRACE and GRACE-FO satellites, respectively.
The dataset is available on the Swarm dissemination server at the following paths:
