Output Variables

PEcAn converts all model outputs to a single standard. This standard evolved out of MsTMIP project, which is itself based on NACP, LBA, and other model-intercomparison projects. This standard was expanded for the PalEON MIP and the needs of the PEcAn modeling community to support variables not in these standards.

Model developers: do not add variables to your PEcAn output without first adding them to the PEcAn standard table! Also, do not create new variables equivalent to existing variables but just with different names or units.

Model specific input files

List of inputs required by model, such as met, etc.

Model configuration files

MODEL is configured using 3 files which are placed in the run folder, as well as a symbolic link to the met file.

• file1 : template for this file is located at models/MODEL/inst/file1 and is not modified.
• file2 : template for this file is located at models/MODEL/inst/file2 and is not modified.
• file3 : template for this file is in models/MODEL/inst/file3 or it is specified in the <model> section as <template>. The values in this template are replaced by those computed in the earlier stages of PEcAN.

Installation notes

This section contains notes on how to compile the model. The notes for the VM might work on other machines or configurations as well.

## 32.2 SIPNET configuration

SIPNET is configured using 3 files which are placed in the run folder, as well as a symbolic link to the met file.

• sipnet.in : template for this file is located at models/sipnet/inst/sipnet.in and is not modified.
• sipnet.param-spatial : template for this file is located at models/sipnet/inst/template.param-spatial and is not modified.
• sipnet.param : template for this file is in models/sipnet/inst/template.param or it is specified in the <model> section as <default.param>. The values in this template are replaced by those computed in the earlier stages of PEcAN.

VM

The Downlad.GFDL function assimilates 3 hour frequency CMIP5 outputs generated by multiple GFDL models. GFDL developed several distinct modeling streams on the timescale of CMIP5 and AR5. These models include CM3, ESM2M and ESM2G with a spatial resolution of 2 degrees latitude by 2.5 degrees longitude. Each model has future outputs for the AR5 Representative Concentration Pathways ranging from 2006-2100.

### 32.3.2 CM3

GFDL’s CMIP5 experiments with CM3 included many of the integrations found in the long-term CMIP5 experimental design. The focus of this physical climate model is on the role of aerosols, aerosol-cloud interactions, and atmospheric chemistry in climate variability and climate change.

### 32.3.3 ESM2M & ESM2G

Two new models representing ocean physics with alternative numerical frameworks to explore the implications of some of the fundamental assumptions embedded in these models. Both ESM2M and ESM2G utilize a more advanced land model, LM3, than was available in ESM2.1 including a variety of enhancements (Milly et al., in prep). GFDL’s CMIP5 experiments with Earth System Models included many of the integrations found in the long-term CMIP5 experimental design. The ESMs, by design, close the carbon cycle and are used to study the impact of climate change on ecosystems, ecosystem changes on climate and human activities on ecosystems.
