ACE Radiation Data

ACE Data Table.

ACE radiation data are plotted around periods when science runs were interrupted. Plots start exactly 2 days before the interruption started. The top panel shows differential fluxes of electrons 38-53 and 175-315 (particles/cm2-s-ster-MeV), the middle panel shows differential fluxes of protons 47-65, 112-187, and 310-580 (particles/cm2-s-ster-MeV), and the bottom panel shows anisotropy ratio. The original data are prepared by the U.S. Dept. of Commerce, NOAA, Space Environment Center.
