Welcome to the CAPS/ES4D Gateway

Due to the dramatic increase in demand for our visual demonstration of space weather affects on the ionosphere, these free ES4D images (and the associated CAPS website) - which are intended for educational purposes - represent the ionosphere approximately 3 hours prior to the current time. Also note the images will require a manual refresh for updated images.

Please visit our secure on-line store for purchasing the real-time and forecast capability (which includes a large number of other capabilities for operations) at a $14.95 US monthly or $119 yearly rate. For additional information, please contact us at spacenvironment@spacenvironment.net.

Visit the guide to installing and running the real-time Earth Space 4-D global 4-D ionosphere using Google Earth, which includes the required kml files. This is a dramatic visualization tool showing Earth's ionosphere, and includes the Total Electron Content, Maximum Usable Frequency, foF2, and HF Radio communication conditions.

Visit the Communication Alert and Prediction System Web Site This is a highly utilitarian web and PDA application that provides current data and figures for Solar and Geomagnetic Conditions, the Global Communication Status, the Global MUF/foF2 status, and global scintillation.
