ACE SWICS 2.0 Solar Wind Protons 12-min Data

ResourceID
spase://NASA/NumericalData/ACE/SWICS/L2/PT12M

Description

The SWICS 12-minute proton data contains densities, speeds, and thermal speeds
from the beginning of the mission up to the present day. The densities have
been cross-calibrated to the proton monitors ACE/SWEPAM and WIND/SWE, and
represent a continuous data set that can be used in conjunction with other
SWICS data, or as a stand-alone measurement. For details on the SWICS proton
data, see the release notes provided by the instrument team:
