This dataset comprises numerical outputs from the thermosphere-ionosphere-electrodynamics general circulation model (TIE-GCM) simulations described in the article "Modeling of planetary wave influences on the pre-reversal enhancement of the equatorial F region vertical plasma drift" (Yamazaki & Diéval, 2021).

The TIE-GCM is a numerical model of the coupled thermosphere-ionosphere system (Richmond et al., 1992; Qian et al., 2014). In Yamazaki & Diéval (2021), the model was run under geomagnetically quiet (Kp=1) and high solar-flux (F10.7=200) conditions. The lower boundary of the model at ~97 km was specified with the the thermosphere-ionosphere-mesosphere electrodynamics general circulation model (TIME-GCM) (Roble & Ridley, 1994), which itself was constrained by the data from the Modern Era Retrospective-analysis for Research and Applications (MERRA) (Reinecker et al. 2011) for the year 2009. In this way, the TIE-GCM is able to reproduce effects of atmospheric forcing from the lower and middle atmosphere.

In addition to the simulation described above, which are referred to as "reference", Yamazaki & Diéval (2021) performed two other simulations with modified lower-boundary forcing. They are referred to as "no_PW" and "tides_only". See Yamazaki & Diéval (2021) for descriptions of different cases. The simulation results from these three cases are saved in separate files in a MATLAB format with a .mat extension. The model outputs from "reference", "no_PW", and "tides_only" cases can be found in "reference.mat", "no_PW.mat", and "tides_only.mat", respectively.

Each file contains the following variables:
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
doy [365 x 1 ] : day of year
longitude [1 x 144] : longitude (degrees)
PRE_Vz [365 x 144] : intensity of pre-reversal enhancement (m/s)
PRE_LT [365 x 144] : local time of pre-reversal enhancement (hours)
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

Descriptions of how PRE_Vz and PRE_LT are determined can be found in Yamazaki & Diéval (2021).
