Several observations are made daily, centered around local noon. Each value reported is a weighted average of all measurements for that day. The weighting arises from effects that include solar rotation, limb darkening, and weakening of the sensitive absorption line within active regions.Scientific Research1948UnknownUnknownIn workdailyNASA/Global Change Master Directory (GCMD) Earth Science KeywordsEarth Science > Solid Earth > Geomagnetism > Magnetic FieldEarth Science > Sun-Earth Interactions > Ionosphere/Magnetosphere Dynamics > Magnetic Fields/Magnetic CurrentsRestriction Code: otherRestrictions; 20111117Solar Data ManagerDOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commercemailing and physical NOAA/NESDIS/NGDC E/GC2 325 Broadway BoulderCO80305303.497.6133 or 303.497.6323solar.ngdc@noaa.govContent Standard for Digital Geospatial Metadata: Extensions for Remote Sensing MetadataFGDC-STD-012-2002
