NOAA SPACE WEATHER SCALES TABLES

This page presents the three Space Weather Scales tables that NOAA uses to inform the "general public the current and future space weather conditions and their possible effects on people and systems."¹

The three tables describe:

1. Geomagnetic Storm Scales
2. Solar Radiation Storm Scales
3. Radio Blackout Storm Scales

NOAA Space Weather Scales Information

Storm scale tables appear in the following order: 1) Geomagnetic Storm Scales, 2) Solar Radiation Storm Scales, and 3) Radio Blackout Storm Scales. The scales in each table range from 1 - 5, with 1 being the least intense and 5 the most intense.

Geomagnetic Storm Scales range from G1 - G5; Solar Radiaiton Storm Scales range from S1 S5; Radio Blackout Storm Scales range from R1 - R5.

Simply read the description and effect for each range in order to get a sense for the environmental effects to expect with each storm scale.
