1) Ocean tidal model FES2014b. It defines height of 34 tidal constituents 
   at the uniform grid with resolution 0.0625 x 0.0625 degrees.

   Solution FES2014, a new tidal model - Validation results and 
   perspectives for improvements, presentation to ESA Living Planet 
   Conference, Prague 2016.

   In addition, 10 sidelobes of the main tidal constituents
   MF+, MTM+, Q1-, O1-, K1-, K1+, J1+, N2-, M2-, K2+ were added.
   Their frequencies differ from the frequencies of the main tides by
   -+ 1.06D-8 rad/sec. The complex amplitudes of water height of sidelobe
   (H') and the main tide (H) are related to the complex amplitudes of 
   their tide generating potentials A and A' via the admittance 
   relationship:

   H'c + i H's     A'c + A's
   ----------- = -----------
   Hc  + i Hs      Ac  + i As

   Here Hc denotes the cosine term in harmonic constituent and Hs 
   denotes the sine term of the harmonic constituent.

   In total, 44 tidal constituents are considered.

   The original FES2014b model was extrapolated inland up to 6 cells.
   Extrapolation was performed by convolution with the exponential
   kernel. The inland extrapolation was done to avoid Gibbs phenomena
   when windowed land-sea mask is applied before spherical harmonics
   transform.


2) The Love numbers have been computed using REAR software,
   Melini  D.,  Gegout  P.,  Spada  G,  King  M.  (2014), "REAR -- 
   a regional  Elastic  Rebound  calculator. User manual for version 1.0", 
   available on-line at  http://hpc.rm.ingv.it/rear.
   Earth reference model STW105 (Kustowski et al., 2007), which is an update 
   of PREM (Dziewonski and Anderson, 1981) was used. The elastic rheology 
   of the Earth derives from the waves speed and the density, with the top 
   three kilometers of oceanic water replaced by underneath rock materials.  
   The model defines the Earth (hydrostatic) equilibrium, the pressure and  
   the gravity inside the Earth; numerical computations allow to take 
   compressibility into account. The Love numbers are computed in the 
   coordinate system with the centrum at the center of mass of the total 
   Earth: solid Earth, ocean, and the atmosphere. Therefore, loading 
   displacements computed with using such Love numbers are the displacements 
   with respect to the center of mass of the total Earth that includes 
   the ocean.
