There are a few differences between old and new high resolution OMNI data sets:\\n\\n* 1) In the newly modified Level-3 OMNI data files, we used the Wind SWE plasma definitive data rather than the Wind SWE plasma KP-despiked data. Using the definitive data give us possibility to include the Alpha/Proton Density Ratio and to use more accurate plasma parameters. However, the time coverage in the new OMNI data was decreased by from 2% to 10%. See the data description at https://spdf.gsfc.nasa.gov/pub/data/omni/high_res_omni/modified/. For detail comparison 1 min SWE definitive and cross-normalized SWE Key Parameter data sets, see https://omniweb.gsfc.nasa.gov/ftpbrowser/wind_pla_def_kp_norm.html.\\n* 2) To keep the number of words and the record lengths the same as in the old OMNI high resolution data set, we replaced the PCN Index (word #45) in the ASCII records with the new Alpha/Proton Density Ratio parameter.\\n* 3) The latest date for these new data is usually behind of the OMNI based on SWE_KP data.\\n\\nModifications:\\n\\n* 1) Conversion to ISTP/IACG CDFs via SKTEditor, February 2000\\n* 2) Time tags in CDAWeb version were modified to use the CDAWeb convention of having mid-average time tags rather than OMNI original convention of start-of-average time tags, March 2005", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://omniweb.gsfc.nasa.gov/html/HROdocum.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://omniweb.gsfc.nasa.gov/html/hro_news.html", "format": "HTML", "mediaType": "text/html"}, {"@type": "dcat:Distribution", "downloadURL": "https://omniweb.gsfc.nasa.gov/ow_min.html", "format": "HTML", "mediaType": "text/html"}], "identifier": "https://doi.org/10.48322/hkaw-ff03", "keyword": ["activityindex", "electricfield", "energeticparticles", "ephemeris", "magneticfield", "thermalplasma"], "landingPage": "https://doi.org/10.48322/hkaw-ff03", "license": "https://www.usa.gov/government-works", "modified": "2026-06-08", "programCode": ["026:000"], "publisher": {"@type": "org:Organization", "name": "NASA Space Physics Data Facility (SPDF) Data Services"}, "theme": ["Heliophysics"], "title": "OMNI, Combined Solar Wind Plasma Moments and Interplanetary Magnetic Field (IMF) Time-Shifted to the Nose of the Earth's Bow Shock, plus Geomagnetic Indices, 5 min Data"}
