Solar Wind Shifted to the Earth Merged Wind hourly SWE definitive Plasma and 3DP plasma parameters ( non normalized to SWE)

This Hourly "Near-Earth" Solar Wind plasma merged data set was created at GSFC/SPDF for comparison of two plasma Instuments sitting on Wind spacecraft.
This Interface may be usefull for calculating derived parameters (that initually were included in OMNI2 ) taking into account 3DP parameters of Protons and Alpha particles where there are no these SWE parameters .
For this Interface we added plot option that provides more easier way to compare one type of parameters ( e.g. Speed, or Density, or.., etc) from different sources with each others ( up to four plotting at one panel), see below.

More information about SWE_definitive and plasma 3DP user may find at
