Swarm Rate Of change of TEC (ROT) - Product description and access

The Rate Of change of TEC (ROT) is used to monitor small scale variability. TEC is the integrated electron density between the Swarm and a given GPS satellite. It is known that large fluctuations in electron content through which the GPS ray is passing can seriously affect GNSS and create radio wave scintillations that degrade significantly solutions for positioning and navigation. With the demand of enhanced accuracy of GNSS alerts on its reliability increase more and more in importance.

SUA ROT is provided as data product with a 1Hz cadence. ROT is derived from the Swarm mission operational product TECx_TMS_2F (Swarm L2 TEC product description) as the first time derivative of the Total Electron Content (TEC) observations. The data are provided in daily files in ASCII format. The product names are ROTxTMSSWE, with x = A, B, C for the 3 satellites respectively.
