Welcome to International Space Environment Service
The International Space Environment Service (ISES) is a permanent service of the Federations of Astronomical and Geophysical Data Analysis Services (FAGS) under the support of the International Union of Radio Science (URSI) in association with the International Astronomical Union (IAU) and the International Union of Geodesy and Geophysics (IUGG).
The data exchanged are highly varied in nature and in format, ranging from simple forecasts or coded information up to more complicated information such as images. An important strength of the data exchange system is that RWCs often have access to data from unique instrumentation available from the scientific community in its region.
The URSIgram codes were originally developed to facilitate the rapid exchange of information by telex. Nowadays, with the internet, compression of information for telex is no longer necessary. However, coded data are still useful as they are easier than text messages to ingest into automatic forecast programs.
Spaceweather.org is sponsored by ISES. It is a gateway to access the most updated space weather information, including HF radio frequency, Space weather in the solar system and much more.
