2.3.1 spase://CNES/NumericalData/CDPP-AMDA/Geotail/CPI/gtl-cpi-swa SWA Solar Wind Analyser 2019-05-05T12:34:56Z The Solar Wind Analyzer (SWA) of the Comprehensive Plasma Instrumentation (CPI) on Geotail is a quadrispherical plasma analyzer that measures three-dimensional fluxes of ions in the range 150-7,000 eV/Q. Version 6 data processing replaced version 5 processing for data after March 10, 2006, when the CPI team started using 64 energy steps per spectrum instead of the previously used 32 steps per spectrum. The change was made to ensure that even for very cold flows, the spectrum would have a sufficient number of significant points to derive moments. The change resulted in 96s spectra and 96s-resolution moments, vs. 48s previously. CPI/SWEA and LEP measurement are expected to be used in a complementary way. LEP is highly sensitive and is dedicated to measure tenuous plasma of the magnetosphere. However, when GEOTAIL is in the interplanetary, LEP generally scans only the high energy (> 5 KeV) part of the ion distribution. This automated mode allows to assure long term preservation of the LEP detectors. The LEP ion moments obtained in the inteerplanetary medium should be used only for qualitative purposes. The ion moments in the interplanetary medium are provided by the CPI/SWEA instrument designed for measuring the denser magnetosheath and solar wind plasma. In any publications, the use of the Geotail data should be acknowledged spase://SMWG/Person/Louis.A.Frank PrincipalInvestigator spase://SMWG/Person/William.R.Paterson GeneralContact spase://SMWG/Repository/CNES/CDPP-AMDA Online Open AMDA at CDPP http://amda.cdpp.eu NetCDF None Data provider DARTS at Institute of Space and Astronautical Science, JAXA in Japan CDAWeb ge_h0_cpi spase://CNES/Instrument/CDPP-AMDA/Geotail/CPI EnergeticParticles 1992-09-28T00:00:02Z 2019-06-26T23:59:28Z PT96S Earth.Magnetosheath Earth.Magnetosphere Earth.Magnetosphere.Magnetotail v_gse gtl_cpi_swa_v Ion bulk flow velocity (H+ only in solar wind) in GSE cartesian coordinates km/s Cartesian GSE TimeSeries 3 vx Component.I 1 gtl_cpi_swa_v(0) vy Component.J 2 gtl_cpi_swa_v(1) vz Component.K 3 gtl_cpi_swa_v(2) density gtl_cpi_swa_n Ion number density Assuming no helium (0.3 - several hundred) if the density is less than 0.3/cc the higher moments (VEL,TEMP) shall not be used because of the poor counting statistics. cm^-3 TimeSeries temperature gtl_cpi_swa_t Ion average kinetic temperature eV TimeSeries
