ttimm is a Fortran program that computes predicted tide time-series.

ttimm reads so-called BLQ-files, results from e.g. the Automatic Loading Provider, and produces equal-spaced time series.

For GNU and Intel compilers 1):  Download   ttimm-v1.14-gnu+intel.tar.bz2

For ABSOFT Fortran 77, Download ttimm-v1.14-absoft.tar.bz2

N.B. Update with ttimm-v1.14u.tar.bz2  to comply with the Feb.5, 2018, update of loading service BLQ scaling concerning gravity.
Notify us if the update appears incompatible with Intel or GNU.
Suggestion: compile the subroutines one-by-one and report the problem cases. Mail to hgs kanelbulle
No warranty concerning Tilt until tests have been passed; no promises as to a date.

Issue v1.14 from 2015-08-13:

Changes w.r.t. Version 1.12:
Version 1.13 can compute Tilt.
No major revision.
Code revisions and bug extinguishing for which the kind help of Hartmut Wziontek, BKG, is gratefully acknowledged.
Code can be compiled with GNU gfortran, Intel Fortran, and Absoft Fortran 77 (V.11.5)

Update patch v1.14u 20018-04-07:
 - unpack and replace the previous subroutines. You need to manually move ttimm.f to replace the main program, sorry.
oltide.f has been revised in order to accept the nm/s^2 scaling of gravity introduced Feb. 5, 2018.

Changes w,.r.t. Version 1.13:
New namelist parameter  q_inject_leaps
If .true., injects UTC leap seconds into the output tsf-file

How to compile under Absoft Fortran 77 is explained in the Read-me file. You can use it to cut and paste at a command line or to code your own make-file.
