Changelog ========== v3.0.2 (Mar 14, 2026) --------------------- * Enhancement: GNU 11.3.1 compiler compatibility (Yuanjian Zhang, WUSTL). * Enhancement: Performance improvements to PNETCDF diagnostics. * Bugfix: Chemistry timestep setting (chemdt) was not being applied. * Bugfix: Fix landmask mapping. v3.0.1 (Aug 16, 2025) --------------------- * Bugfix: Fix missing MEGAN biogenic emissions when using fractional minute timesteps. * Bugfix: Fix leaf area index (LAI) data incorrectly passed to GEOS-Chem from coupler resulting in dry deposition issues. * Bugfix: Backport upstream HEMCO fix for MESSy vertical regridding for emissions. * Bugfix: Build dependency fixes. v3.0 r2 (Oct 27, 2024) --------------------- * Enhancement: Update specialty simulation couplers to use pnetCDF-based diagnostic output. * Bugfix: Update WRF-GC diagnostic support for multiple domains. * Bugfix: Build dependency fixes. v3.0 (April 22, 2024) --------------------- * 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 `_ it may not be necessary to use ParaNOx for high-resolution simulations with WRF-GC. * Bugfix: Initial condition input bug for nested domain(s). v2.0.2 (September 30, 2022) ---------------------------- * Bugfix: Initial condition input bug for nested domain(s).
