Report on the design and specifications of the TID algorithms and products

TechTIDE project, funded by the European Commission Horizon 2020 research and innovation program [AD-1], will establish a pre-operational system to demonstrate reliability of a set of TID (Travelling Ionospheric Disturbances) detection methodologies to issue warnings of the occurrence of TIDs over the region extended from Europe to South Africa. TechTIDE warning system will estimate the parameters that specify the TID characteristics and the inferred perturbation, with all additional geophysical information to the users to help them assess the risks and to develop mitigation techniques, tailored to their application. This document is TechTIDE D2.1 “Report on the design and specifications of the TID algorithms and products” and it is an output of TechTIDE Task 2.1 (Specifications for the TID algorithms and the resulting products) of the WP2 (TID identification methodologies) which has the final goal to release the basic algorithms for the TID identification and the value-added products for implementation in the TechTIDE warning system. The document presents the design of adjusted and upgraded TID detection codes, the design of the value-added products, and the validation plan. The design of the adjustments and the upgrades of the different methods are based on the initial requirements gathered among potential users affected by TIDs [RD-1]. Some requirements were brought in from ESA Space Situational Awareness Space Weather (SSA SWE) [RD-2] users' requirements. This way, TID algorithms and product outputs will try to adapt to assess ESA SSA SWE Service Network prerequisites.
