URSIgram Codes

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.

The URSIgram codes are in the process of being revised. Any comments or suggestions for the codes should be sent to Graham Stewart, ISES Secretary for Space Weather.
