- Updates to forward model

Add NEI2008 Emissions

Implemented NEI2008 Emissions Inventory

See benchmark results gcadj_std_v35 tests 003 and 023

--Yanko 15:28, 24 July 2013 (EDT)

EDGAR v4.2 emissions for CH4 simulation

Kevin Wecht has prepared EDGAR v4.2 emissions of methane for 2004-2008. See forward wiki.

--Yanko 15:15, 11 April 2014 (EDT)

Update anthropogenic scale factors through 2010

Annual anthropogenic scale factors will be extended to 2010 for U.S.A. and Canada. See forward wiki.

--Yanko 15:15, 11 April 2014 (EDT)

Update GFED3 emissions to 2011

Updated the GFED3 database to include data for 2011. See forward wiki.

--Yanko 15:15, 11 April 2014 (EDT)

Update TOMS overhead O3 columns to 2010

Jenny Fisher has updated to TOMS overhead O3 columns to account for years through December 2010. See forward wiki.

--Yanko 15:15, 11 April 2014 (EDT)

Added support for HTAP emissions inventory

A new module was developed in order to add support for HTAP emissions inventory. This update alongside some other small changes made possible the participation on the HTAP experiment . You can find more information about HTAP here.

--Yanko 16:03, 10 July 2014 (EDT)

Updated aerosols optical properties

Aerosols optical properties were updated to match the forward model v9-02q in which the user can specify the wavelenght (default 550nm). This updates also improves the representation of OC growth with RH and also made some correction to sulfate optics See forward wiki.

--Yanko 16:03, 10 July 2014 (EDT)

- Bug fixes in forward model

Fixed a bug in Henry's constant

Small error in the definition of the Henry's constant, which is used in the wet deposition routine. See forward wiki.

--Yanko 15:28, 24 July 2013 (EDT)

Prevent negative emissions over Canada

Found a nasty bug in CAC emissions. We should set the emissions to 0 when 2002 exceeds 2005 by more than a factor of three. See forward wiki.

--Yanko 15:28, 24 July 2013 (EDT)

Bug fix in grid_mod.F90

The sine of the last latitude edge (i.e. the north pole) is not calculated, which can cause problems for the regridding. See forward wiki.

--Yanko 14:38, 30 October 2013 (EDT)

Bug in ship CO emissions

EMEP ship emissions inventory was previously overwriting all ship CO emissions globally. See forward wiki.

--Yanko 19:02, 30 October 2013 (EDT)

Bugs in ship emissions and non-local PBL mixing

Ship NOx emissions with the ICOADS-AMVER inventory were 3.3 times too low, due to a NO2 vs. N molecular weight error. Emissions should be 5.0Tg(N)/yr. As a result, O3 and HNO3 concentrations were underestimated, especially over the N. Atlantic and N. Pacific. See forward wiki.

--Yanko 19:02, 30 October 2013 (EDT)

Eliminate several more array temporaries

In many areas of GEOS-Chem, we pass arrays as arguments from one routine to another. But if this is not done properly, it can cause GEOS-Chem to use an excessive amount of memory and take longer to run, especially at very fine resolutions. See forward wiki.

--Yanko 14:38, 30 October 2013 (EDT)

Bug fix for 3-hourly GFED3 emissions

Running with 3-hourly emissions from the first day of a month seems to work fine, but trying to start on any other day appears to cause a problem. See forward wiki.

--Yanko 17:11, 27 January 2014 (EST)

Emfossil Bug Fix

Fixed a bug on emfossil.f that made the model crash when ND49 diagnostic was turned on and NEI2005 emissions were used. If you want to see the changes on the code please find them here

--Yanko 16:03, 10 July 2014 (EDT)


- Updates to adjoint model

Add support for new deposition based cost functions

Added support for new deposition based cost functions.

See benchmark results gcadj_std_v35 tests 012 and 023

--Yanko 15:28, 24 July 2013 (EDT)

Implemented new ship emissions scheme

Implemented new ship emissions scheme matching forward model paranox module. Changes to the adjoint include, but are not limited to writing the adjoint of paranox and updating setemis_adj module.


See benchmark results gcadj_std_v35a tests

--Yanko 14:38, 30 October 2013 (EDT)

- Bug fixes in adjoint model

Small bug fix in wetscav_adj_mod.f

Fixed a small bug related to the ALPHA2 variable on WETDEP_ADJ subroutine in wetscav_adj_mod.f

--Yanko 15:28, 24 July 2013 (EDT)

GFED2 8 Day Bug Fix

GFED2 data was not read correctly in the backward calculation if the simulation include the first day of the year ( January 1st ). Because the last day of GFED2 data in December is Dec 27th, and the first day of January is 1st, so the gap is not 8 day.

--Yanko 15:25, 24 January 2014 (EST)

Deposition Diagnostics Bug Fix

Fix wetdep diagnostics 37, 38 and drydep 44, which previously did not include all species.

--Yanko 15:25, 24 January 2014 (EST)

Loose ANISO convergence

The convergence criteria for ANISO have been relaxed to allow for quicker calculations.

--Yanko 15:25, 24 January 2014 (EST)

Off Diagonal Covariance Bug Fix

Off diagonal covariance fix.

--Yanko 15:25, 24 January 2014 (EST)

LBFGS allocation Fix

LBFGS allocation fix, and also update to more recent implementation of the algorithm (v3.0).
