Space Weather Nowcast and Forecast Products (Daily, Weekly)

Welcome to the General Data Services - Forecast and nowcast service service


Data lies at the heart of ESA's Space Weather activities. Many of the user requirements and components to be delivered as part of the SWE segment make reference to requirements on the availability of and access to nowcasting and forecasting data. This includes real-time and near-real-time delivery of measurement and modelling data.

The General Forecast service provides access to the nowcasting and forecasting data included in the ESA SWE service network.

This service is implemented through a combination of products, tools and alerts which can be found in the sections below with expert support provided by the teams constituting the SWE Network. Should you require further guidance in the use of this service, or have specific questions about any aspects of the service presented here, don’t hesitate to contact the SSCC Helpdesk.
