E3SM v3.0.2. Second patch release of v3.0.

E3SM v3.0.2. Second patch release of v3.0. The main purpose of this release is to fix the forcing specifications of v3 single-forcing compsets. Core to the changes is to separate the transient aerosol and chemical precursors for different single forcing compsets. New virtually transient forcing files are introduced to satisfy the unified data stream control for surface and elevated emissions. Historical evolution of stratospheric ozone is moved from the all-else configuration to the GHG only configuration.

These compets will change answers: WCYCL20TR-GHG, WCYCL20TR-aer, WCYCL20TR-xGHG-xaer, WCYCL20TR-xaer. Except for those compsets, the simulated climate is identical for compsets released in v3.0.0 and released/updated in v3.0.1.

Other changes:

EAM: fix output of r_lch4 and r_lco_h reaction rates.

ELM: The precision of a few real variables is fixed during model initialization. New parameterizations are added for the burial of shrubs by snow; however, these parameterizations are not on by default.

EAMxx: Downstream merge from SCREAM repo.

MPAS-ocean: fix bug in data sub-glacial runoff. Add new SOwISC12to30E3r3 mesh.

MPAS-seaice: Update BGC history fields.

Land Ice: Add ERA5r025 configurations for new IGERA5ELM_MLI compsets

Wave model: Change location of WW3 compilation, update wave developer test suite.

Data models: Add support for new JRA forcing through year 2023.
