Software

  • DEHANTTIDEINEL.F - Subroutine to compute tidal corrections of station displacements caused by lunar and solar gravitational attraction.[1] (Updated 23 October 2007, 19 February 2009, 10 April 2009, 26 March 2012, 10 June 2013, 19 June 2015.)
    • All subroutines needed for compilation are provided on our FTP site.
  • HARDISP.F - Program to compute ocean tidal loading from a table of amplitudes and phases of the 11 main tides.[2] (Updated 19 February 2009, 10 April 2009, 26 March 2012, 19 June 2015.)
    • All subroutines needed for compilation are provided on our FTP site.
  • ARG2.F - Subroutine to compute the angular argument which depends on time for 11 tidal argument calculations.[3]
    • This routine replaces the previous 2003 Conventions routine, ARG.F. Main changes are the use of double precision for all variables and of the four-digit year as an input argument.

Additional Information

  • annual.pole - Table of yearly mean of pole coordinates from 1976.0 to 2010.0, used to generate the IERS (2010) mean pole model in Section 7.1.4.[4]
  • The subroutine, IERS_CMP_2015.F, was developed to estimate the Conventional Mean Pole, and is available in the Updated Chapter 7. This software is not a part of the official 2010 distribution.
  • opoleloadcoefcmcor.txt.gz - Table of coefficients for the ocean pole tide loading model (gzipped).[5]
  • opoleloadcmcor.test - Test run for the ocean pole tide model.[5]
