2026-07-30 The energetic particle event related to the stream interaction region on 1 Feburary 2008 doi:10.57760/sciencedb.44714 en The dataset1 comprises solar wind plasma, magnetic field, and 0.32–1.81 MeV proton flux measurements from three spacecraft—STEREO-A, STEREO-B, and WIND—during late January to early February 2008. The three satellites are positioned near the ecliptic plane at different heliocentric longitudes, enabling multi‑point in‑situ observations. STEREO-B covers the period from 29 January to 3 February 2008, providing 1‑minute plasma and magnetic field data (daily files named 2008xxxx_1min_STB.txt) and 10‑minute proton intensity data (SIT_10min_STB.txt). WIND spans 31 January to 5 February, supplying 1‑minute plasma (plasma_1min.txt) and magnetic field (magnetic_field_1min.txt) data, along with hourly proton intensity (STEP_1hr.txt). STEREO‑A covers 1 to 6 February, with 1‑minute plasma and magnetic field data (daily files 2008xxxx_1min_STA.txt) and 10‑minute proton intensity (SIT_10min_STA.txt). In addition, the dataset2 includes simulation results of energetic proton evolution at the corresponding locations of the three spacecraft, named STA.dat, STB.dat, and WIND.dat, all with 1‑hour temporal resolution and covering the same time intervals as the observations, facilitating direct comparisons with measured proton fluxes.
