GALE - Synthetic Dopplergram Series of Differential Rotation Synthetic Dopplergram data generated by the GALE code (Stejko et al. 2021; https://doi.org/10.3847/1538-4365/abd3fe)---a 3D Solar linearized acoustic code simulating the propagation of p-modes over user-specified background flows. ...

In order to analyze the detection of near-surface shear, we employ two 3D background profiles of differential rotation: the mean-field model M1 of Pipin et al. (2019; https://doi.org/10.3847/1538-4357/ab5952) and the non-linear convectively-driven model N5 of Matilsky et al. (2019; https://doi.org/10.3847/1538-4357/aaf647). The Gale code is actuated at a spectral resolution of lmax = 1000, for 8hr time-series at a cadence of 45s.

In the top-level directory, the following two files contain the direct output of acoustic surface oscillations from the code sampled at 100 km above the simulated solar surface:

   GALE_t8h_l1000_M1.fits    GALE_t8h_l1000_N5.fits

These two FITS files contain outputs in rectangular grids with a resolution of lmax = 1000, corresponding to 3000 mesh points in phi and 1500 mesh points in theta. The meshgrids are attached inside the FITS files on the 2nd and 3rd Image HDUs.

These outputs are subsequently remapped into helioprojective cartesian coordinates (aerial projection) into a 4096 x 4096 pixel image, simulating full-disk observations made by HMI/SDO, stored in the two following directories:

   HMI_M1    HMI_N5

These directories each contain 640 FITS files in the format of hmi.v_45s full-disk dopplergram data products from HMI, uncompressed, and with relevant keywords reflecting the new scale and viewing angle of the simulated images.
