mom_load_love_numbers module reference¶
Load Love Numbers for degree range [0, 1440].
Detailed Description¶
This module serves the sole purpose of storing load Love number. The Love numbers are used for the spherical harmonic self-attraction and loading (SAL) calculation in MOM_self_attr_load module. This separate module ensures readability of the SAL module.
Variable Love_Data stores the Love numbers up to degree 1440. From left to right: degree, h, l, and k. Data in this module is imported from SAL calculation in Model for Prediction Across Scales (MPAS)-Ocean developed by Los Alamos National Laboratory and University of Michigan [Barton et al. (2022) and Brus et al. (2022)]. The load Love numbers are from Wang et al. (2012), which are in the center of mass of total Earth system reference frame (CM). When used, Love numbers with degree<2 should be converted to center of mass solid Earth reference frame (CF) [Blewitt (2003)], as in subroutine calc_love_scaling in MOM_tidal_forcing module.
