3.0.0

This is version 3.0 of WRF-GC, released April 22, 2024.

Please do not download this release as a .zip or .tar.gz file directly. Refer at all times to the instructions in the WRF-GC documentation.

• Feature: Supports GEOS-Chem 14.1.1, KPP 3.0.0, and HEMCO 3.6.2.
• Feature: Supports WRF version 4.4.
• Feature: Infrastructure for specialty simulations. Now can install couplers for fullchem, ch4, and co2 using the install_registry command.
• Feature: Add support for History diagnostics and HEMCO diagnostics ("WRF-GC 3.0 Diagnostics") using pNETCDF.
• Technical Update: Compiles GEOS-Chem 13+ without using CMake by maintaining the legacy GNU infrastructure.
• Technical Update: Auto-patching of wrf_io.F90 to support more than 3,000 variables in wrfbdy.
• Technical Update: No longer inputs initial/boundary conditions for non-advected species through i0{12} switch in registry.chem.
• Enhancement: Recompile no longer wipes configuration files by automatically calling make install_configs. Configuration files are installed once using make install_registry or others for specialty simulations.
• Enhancement: New coupler species generation infrastructure shared with CESM2-GC.
• Enhancement: Support for QV2M met field for online blowing snow emissions.
• Bugfix: Fix stack corruption issue in chemics_init coordinates.
• Bugfix: More robust support for get_last_gas due to WRFv4 upstream updates.
• Bugfix: Month-boundary HEMCO emissions missing timesteps.
• Bugfix: ParaNOx stability issue via upstream GEOS-Chem 14.0.1 fix. Note that according to Colombi et al., 2023 ACP <https://acp.copernicus.org/articles/23/4031/2023/>_ it may not be necessary to use ParaNOx for high-resolution simulations with WRF-GC.
• Bugfix: Initial condition input bug for nested domain(s).
