OMNIWeb: New version of High Resolution OMNI Data

The Modified (Level-3) High Resolution OMNI (HRO) data (at 1-min and 5-min resolution) based on the definitive Wind plasma data. The main difference between the new data old data is the following: For creating this OMNI data set we used shifted Wind/SWE plasma definitive data rather than Wind/SWE shifted plasma KP-despiked data. A user can get more accurate plasma parameters and "Alpha/Proton Density Ratio" parameter: (that parameter is not available in the SWE KP data). However, the time coverage in the new OMNI data was decreased by 2-10% (depending on the year) and latest date of these new data sets usually behind of the OMNI based on SWE_KP data.
