This dataset comprises numerical outputs from the whole atmospheric model GAIA (=Ground-to-topside model of Atmosphere and Ionosphere for Aeronomy) and associated simulations presented in the article "Whole atmosphere model simulations of ultra-fast Kelvin wave effects in the ionosphere and thermosphere" (Yamazaki et al., 2020).GAIA is a numerical model of the Earth’s whole atmosphere (e.g., Jin et al., 2011; Miyoshi et al., 2011). The model consists of mathematical equations appropriate for various physical and chemical processes in the troposphere, stratosphere, mesosphere, and thermosphere. The neutral atmosphere model (Miyoshi & Fujiwara, 2003) is coupled with an ionospheric model (Shinagawa, 2011) and electrodynamics model (Jin et al., 2008). The lower layers of the model below 30 km are constrained by meteorological reanalysis products by the Japan Meteorological Agency (Onogi et al., 2007; Kobayashi, et al., 2015).The model was run for the following three time intervals:1. 15 August 2010 - 15 October 20102. 01 August 2011 - 30 September 20113. 01 December 2012 - 31 January 2013The simulation outputs can be found in GAIA/2010, GAIA/2011, and GAIA/2013, respectively. In each directory, the model data are stored in a MATLAB format (.mat).List of model outputs:GZ: "Geopotential height" in [m] as a function of LONGITUDE [˚], LATITUDE [˚], PRESSURE, and TIMEGU: "Zonal wind" in [m/s] as a function of LONGITUDE, LATITUDE, PRESSURE, and TIME (positive eastward)GV: "Meridional wind" in [m/s] as a function of LONGITUDE, LATITUDE, PRESSURE, and TIME (positive northward)GT: "Temperature" in [K] as a function of LONGITUDE, LATITUDE, PRESSURE, and TIMEEEF: "Equatorial zonal electric field" in [V/m] as a function of LONGITUDE and TIME.TEC: "Total electron content" in [TECU] as a function of LONGITUDE, LATITUDE, and TIMEPRESSURE is given at: 10^2, 10^1, 10^0, 10^(-1), 10^(-2), 10^(-3), 10^(-4), 10^(-5), 10^(-6), 10^(-7), 10^(-8) [hPa]For the time period #1, additional controlled simulations "LARGE_WAVES" and "NO_UFKW" were run. See Yamazaki et al. (2020) for details of these runs. The simulation outputs can be found in LARGE_WAVES/2011 and NO_UFKW/2011, respectively.
This dataset comprises numerical outputs from the whole atmospheric model GAIA (=Ground-to-topside model of Atmosphere and Ionosphere for Aeronomy) and associated simulations (EXP1, EXP2, and EXP3) presented in the article "Excitation mechanism of ionospheric 6-day oscillation during the 2019 September sudden stratospheric warming event" (Miyoshi and Yamazaki, 2020).
Briefly, GAIA is a numerical model of the Earth’s whole atmosphere (e.g., Jin et al., 2011; Miyoshi et al., 2011, 2012). The model consists of mathematical equations that represent various physical and chemical processes in the troposphere, stratosphere, mesosphere, and thermosphere. The neutral atmosphere model (Miyoshi & Fujiwara, 2003) is coupled with an ionospheric model (Shinagawa, 2011) and electrodynamics model (Jin et al., 2008). The lower layers of the model below 40 km are constrained by meteorological reanalysis products by the Japan Meteorological Agency (Kobayashi, et al., 2015).
The model was run for the period 1 September-10 October 2019, when there was a sudden stratospheric warming in the Antarctic region (Yamazaki et al., 2020). The GAIA simulation outputs can be found in the directory 'gaia', while the numerical outputs from the controlled simulations EXP1, EXP2, and EXP3 can be found in the directories 'exp1', 'exp2', and 'exp3', respectively. The model data for the temperature, zonal wind, meridional wind, and geopotential heigh are stored separately for each day in the NetCDF format. 'gt', 'gu', 'gv', and 'gz' in file name indicate the temperature, zonal wind, meridional wind, and geopotential heigh, respectively. For instance, the file 'gv20190915gcm.nc' contains the meridional wind data for 15 September 2019. The model data for the eastward current intensity, eastward electric field, and total electron content can be found as text files, namely, 'East_current_gaia.data', 'East_efield_gaia.data', and 'tec_gaia.data'.
