2.3.1 spase://CNES/NumericalData/CDPP-AMDA/OMNI/omni-1min-all 1 min One min averaged 2015-10-15T14:34:00Z 1 min averaged, multi-source, near-Earth solar wind magnetic field, plasma and energetic proton flux data, plus AE, AU, AL, Kp, ap, and Dst geomagnetic indices, Polar Cap (Thule) index, F10.7 index, and Rz (sunspot number). The ram pressure is calculated using P=rho*Np*Vp², where rho=1.672622*(1+4*(1/(1-He++_ratio)-1)). We use rho=2 here, which corresponds to a ratio of He++ between 4% and 5%. We acknowledge the experiment teams that acquired, processed and provided the OMNI-included data, and J.H. King and N.E. Papitashvili of NASA/GSFC for creating the OMNI data set. spase://SMWG/Person/Joseph.H.King GeneralContact spase://SMWG/Person/Natalia.E.Papitashvili TechnicalContact OMNI documentation at OMNIWeb http://omniweb.sci.gsfc.nasa.gov/html/ow_data.html Extensive OMNI documentation pages spase://SMWG/Repository/CNES/CDPP-AMDA Online Open AMDA at CDPP http://amda.cdpp.eu NetCDF OMNIWeb Calibrated spase://CNES/Instrument/CDPP-AMDA/OMNI ThermalPlasma MagneticField EnergeticParticles ActivityIndex 1981-01-01T00:00:00Z 2020-10-30T23:55:00Z PT60S Heliosphere.NearEarth sw |b| omni1_imf_mag phys.magField nT TimeSeries 9999.9 Average Magnetic sw b_gse omni1_imf phys.magField nT TimeSeries 3 bx 1 omni1_imf(0) 9999.9 by 2 omni1_imf(1) 9999.9 bz 3 omni1_imf(2) 9999.9 Magnetic sw density omni1_sw_n phys.density;phys.atmol.ionStage cm-3 TimeSeries 999.99 Ion Electron Proton NumberDensity sw temperature omni1_sw_t phys.temperature;phys.atmol.ionStage K TimeSeries 9999999.
