v3.5.0

Minted inputs and output archived at are included with release assests.

What's Changed

• Minor documentation changes
• Several variables/parameters were renamed, FCH4 -> RF_CH4, alpha -> aero_scalar, & volscl -> vol_scalar
• Change RF vol implementation so it is not negative in the future period
• Expose soil and detritus RH fluxes as possible Hector outputs, RH_DETRITUS() & RH_SOIL()
• Add ALL_VARS() which helps users fetch all Hector output variables
• Update [CH4] lifetime parameters
• Allow for time varying historical N2O and CH4 natural emissions
• New default parameter values for ocean heat diffusivity, CO2 fertilization, and heterotrophic respiration temperature sensitivity from calibrating Hector to historical observations of gmst (Morice et al. 2021), [CO2] (Meinshausen et al. 2020), and ocean heat content (Kuhlbrodt et al. 2023)

Full Changelog: v3.2.0...v3.5.0

v3.2.0

• Correct aerosol forcing coefficients based on Zelinka et al. (2023)
• Enable permafrost module and recalibrate model's default parameterization

V3.1.1

Hector V3.1 added global mean surface temperature as an output available to Hector users, the Hector V3.1.1 release fixed documentation inconsistencies related to Hector version numbering.

oceanMIP

The version of Hector that was submitted runs to the SCM ocean heat-carbon nexus study.

v3.1.0

Add global mean surface temperature as a Hector output.

v3.0.1

Minor update to the citation file for the v3 release.

v3.0.0

This is the PR containing all of the developments post v2.5 release, it has been a large and lengthy process. Many developers have worked on this PR not limited to but including @bpbond, @leeyap, @skygering, @ashiklom, @dawnlwoodard, @pralitp. At least 73 peer-reviewed PRs were merged into this branch.

The major changes are noted in the News section of the online documentation and will be further documented in the Hector v3 manuscript that is currently in prep (final manuscript information to be added here after publication). Since the quality analysis was completed during each stage of development and for detailed questions, refer to the individual PR where the development was completed. The documentation included in this PR will provide some wholistic general information about Hector behavior changes and performance.

Hector version 2.3.0

• Constrain atmospheric CO2 concentration to be equal to the
  preindustrial concentration during the model spinup. The result of
  this is that the concentration at the beginning of the simulation
  will be equal to the value specified in the PREINDUSTRIAL_CO2
  parameter, which was not the case previously.

Hector version 2.2.2

• Fix bug that was causing requests for H2O forcing in the R interface
  to return N2O forcing instead (the model internals were
  unaffected).
• Fix bug that was causing API requests for halocarbon forcing to
  return absolute forcing values, rather than values relative to the
  base year (which is what is done for all other forcings).
• Add missing capability dependency in forcing component.
