Add GFED3 Emissions

Implemented GFDE3 Emissions

See benchmark results gcadj_std_v34 tests 005 and 006

--Yanko 19:06, 14 November 2012 (EST)

Checkpoint files creation updated

Now *chk* files are not created at X=0. Checkpoint files are not created at X=2, 3 if performing a finite diference test.

--Yanko 19:06, 14 November 2012 (EST)

Population_mod Updated

population_mod.f updated.

--Yanko 19:06, 14 November 2012 (EST)

Update to Nested Domains

Improved nested simulations. STRAT_CHEM update for regrid GMI files to nested domain.

See Benchmarks results gcadj_std_v34b

--Yanko 15:53, 25 January 2013 (EST)

Added support for ICOADS ship emissions

Added support for ICOADS ship emissions.

- Bug fixes in adjoint model

Fix GFED2 Emissions

Fixed an error when using GFED2 8Daily and 3Hr emissions, the error occurred when running backwards because the emissions were called twice.

See Benchmarks results gcadj_std_v34 tests 003 and 004

--Yanko 19:06, 14 November 2012 (EST)

M Undefined

M Undefined on line 1199 of tagged_co_adj_mod.f, this only affects tagged_co emissions inversions.

--Yanko 19:06, 14 November 2012 (EST)

Error compiling on ifort 12

Fixed an error that made imposible to compile sciabr_co_obs_mod.f on ifort 12. The error was caused by an openmp pragma. This error is entirely a problem of the compiler and not the code itself, this should me resolved on version 13 of the compiler. Meanwhile we just commented the pragma to avoid problems.

--Yanko 19:06, 14 November 2012 (EST)

Set observation errors to 1% in pseudo-obs test

Setting the observation errors to 1% instead of 100% in the pseudo-obs test.

See Benchmarks results gcadj_std_v34a

--Yanko 14:08, 18 December 2012 (EST)

Fixed Makefile Bug

Fixed a Makefile bug preventing 'make help' from running at checkout, also added example of IFORT_OPT flag on run script.
