This dataset contains post-processed monthly output from WACCM (version 4) simulations: historical simulation of 1957–2005 with medium energy electrons (compset B55TRWCN, B55TRWCN.zip) sensitivity study: 50-years experiments designed with different geomagnetic and solar conditions (compset FW, FW.zip) The postprocessing involved (1) zonal averaging, (2) Transformed Eulerian mean (TEM) budget calculation in log-pressure coordindates from model output (h0 files). Contact Monika Szelag (monika.szelag@fmi.fi) Raw data The raw, ungridded monthly data (2TB, h0 files) are currently available on FMI storage system, under path /ibrix/arch/waccm, and can be requested through the contact person.
