Dataset
Atmospheric tidal coefficients from an SD-WACCM-D simulation at two longitudinal slices: the equator and 69 degrees north (2005–2013)
Abstract
This dataset was extracted from two numerical simulations of the Earth's atmosphere calculated using the Specified Dynamics version of the Whole Atmosphere Community Climate Model (WACCM) with D-region ionic chemistry.
Included with both simulations are the fourier coefficients required to calculate the atmospheric tides at two longitudinal slices, one over the equator and one at 69 degrees north. The latter location covers a highly instrumented site, allowing for the inclusion of radar observations of atmospheric tides. The daily mean state of the atmosphere at these two locations is also included. In the first run, both the geomagnetic activity and F10.7 flux provided to the model represented daily means. In the second run, the data have a three-hour temporal resolution.
These data were produced by University of Leeds and British Antarctic Survey (BAS) scientists under Natural Environment Research Council (NERC) project MesoS2D (grant reference: NE/V018426/1).

| Data lineage: |
Data were generated using CESM version 2.1.3 using the Archer2 HPC system with time awarded to the MESOS2D project. The fourier coefficients required to calculate the atmospheric tides were accumulated over the course of a data for the diurnal, semidiurnal, and terdiurnal tides. Data were extracted for two longitudinal slices, one over the equator and one at 69 degrees north, the latter of which allows for the calculation of tides over Tromso, a highly instrumented site. These extracted data were supplied by the project team for archiving at CEDA. |
