The magnetometer has four automatically switchable ranges from ±1024 to ±65536nT (full scale) and resolution commensurate with a 16-bit A/D converter in each range (0.031 to 2nT). The rate of sampling is 32 vectors per second. The characteristics of high sensitivity and high time resolution enable us to observe small-scale field-aligned currents embedded in large-scale field-aligned currents. Intense small-scale field-aligned currents are frequently observed in region 1,region 2 and cusp currents and also in the polar cap region. These currents usually consist of pairs of upward and downward field-aligned currents., 資料番号: SA0166927000}, pages = {99--112}, title = {あけぼの衛星による沿磁力線電流の観測}, volume = {25}, year = {1990} }
