An agency, not a NASA programme
NOAA is an agency of the US Department of Commerce. It is not a NASA programme, although the two organisations collaborate on some missions and use space-based technologies and data.
From the Sun to Earth
NOAA’s Space Weather Prediction Center collects and distributes information on phenomena affecting the environment near Earth, including solar wind and geomagnetic activity. These products help assess potential effects on communications, satellites and technological networks.
Different kinds of information
A measurement, a forecast and an alert are different products. Each must be understood in relation to its source and the time it describes.
