- Updates to forward model

Add GFED3 Emissions

Implemented GFDE3 Emissions

See benchmark results gcadj_std_v34 tests 005 and 006

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

Added support for ICOADS ship emissions

Added support for ICOADS ship emissions.

See Benchmarks results gcadj_std_v34c test 003

--Yanko 13:49, 5 February 2013 (EST)

Add support for RETRO emissions

Added support for RETRO emissions.

See Benchmarks results gcadj_std_v34e test 001

--Yanko 14:14, 14 March 2013 (EDT)

- Bug fixes in forward model

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)

Washout fix for non-aerosol species

The Wet deposition algorithm was underestimating washout of non-aerosol species. See forward wiki.

--Yanko 16:00, 4 March 2013 (EST)

Bug fixes for biofuel emissions

Fix for double-counting of residential biofuel when using RETRO and fix in biofuel emissions using Streets inventory. See forward wiki.

--Yanko 19:43, 13 March 2013 (EDT)

Fix bug in EDGAR ship emissions code

GEOS-Chem default configuration uses the ICOADS ship emissions instead of the EDGAR ship emissions. However, we still pass EDGAR_CO_SHIP to routine COMPUTE_EDGAR_CO even if it is not allocated. See forward wiki.

See Benchmarks results gcadj_std_v34e test 003 to 008

--Yanko 19:43, 13 March 2013 (EDT)

Bug fix for ship NOx emissions

Ship NOx emissions are supposed to be emitted as (1 mol HNO3 + 10 mol O3) per mol NOx in the inventory. The code previously used molar masses incorrectly so that the ratios were actually 0.73 mol HNO3 and 9.5 mol O3. Thus, this bug fix will slightly increase O3 and HNO3 over the oceans. See forward wiki.

--Yanko 19:43, 13 March 2013 (EDT)

Nested Transport Fix

Applied a bug fix that affects transport for nested simulations with GEOS-5 met fields. See forward wiki.

--Yanko 18:59, 4 April 2013 (EDT)

- Updates to adjoint model

Building Process Updated

Building process updated to match forward model. Find more information about changes on the run script on the User's Guide Section 2.4 Page 27

--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)

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)

Added support for off-diagonal covariance

- Now possibility to define correlations (off-diagonal terms) in the background (prior) covariance error matrix. User can define the latitude and longitude correlation length in input.gcadj. See Singh et al. (2011): Construction of non-diagonal background error covariance matrices for global chemical data assimilation, Geosci. Model Dev. ,4, 299-316 for more information.

See Benchmarks results gcadj_std_v34f test 003 to 005

--Yanko 17:38, 4 April 2013 (EDT)

- Bug fixes in adjoint model

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.
