The NGDC Solar and Terrestrial Physics (STP) division provides scientific data stewardship of solar-terrestrial datasets in compliance with NOAA Administrative Order (NAO) 212-15, "Management of Environmental and Geospatial Data and Information", dated 04 Nov 10. Scientific Data Stewardship includes the Archive, Access, and Assessment (AAA) of operational and related solar and space environmental datasets. Data access provided by the NOAA Solar and Terrestrial Physics Division. Numerous solar observatories have contributed to this collection - please refer to the Lineage section of this metadata record. underDevelopment William Denig DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce (303) 497-6323 (303) 497-6513 NOAA/NESDIS/NGDC E/GC2 325, Broadway Boulder Colorado 80305-3337 U.S.A. solar.ngdc@noaa.gov 9:00 - 5:00 Mountain pointOfContact annually ftp://ftp.ngdc.noaa.gov/STP/space-weather/solar-data/solar-features/solar-flares/sids/documentation/browse_sid-event.jpg Diagram showing effect of a sudden ionospheric disturbance (SID) on the usable frequency window which is the unshaded region between the lowest usable frequency (LUF) and the maximum usable frequency (MUF). Normally, both the MUF and LUF increase when the sun rises, thereby keeping a band between them open for HF communications. But during a strong SID, the LUF will increase to a frequency higher than the MUF, thus closing the usable frequency window, an event called a short wave fadeout. Note the rapid onset of the SID that is typical of these disturbances.
