About the data

This page provides logarithmic regressions ("logarithmic regression" is shorthand for "linear regressions of logs of parameters") for density and temperature. It gives possibility to cross-normalize densities and temperatures using the results of the logarithmic regressions because densities and temperatures tend to be more log-normally distributed than linearly distributed.


Time span of data set:
THEMIS-B 2010-01-01 - 2019-04-30 THEMIS-C 2010-01-01 - 2019-04-30 Wind 2010-01-01 - 2019-07-29 ACE 2010-01-01 - 2018-10-04
