This repository contains data files needed to run the gcamfaostat (v1.0.1) package. All the data are publicly available from FAOSTAT and they are downloaded from FAOSTAT in October 2024. This repo serves as an archive of the source data as FAOSTAT continues updating the data. Note that the zip files provide a snapshot of FAOSTAT data since the historical data may also be revised by FAO.

These data should be placed in inst/extdata/FAOSTAT in the R package gcamfaostat v1.0.1. They are used in the package to generate data used in the aglu/FAO folder in gcamdata for GCAM. The package structure ensures the processing is transparent, traceable, and reproducible. gcamfaostat v1.0.1 generates data for GCAM v7.3+.

We have now included more data from FAOSTAT (beyond gcamfaostat needs) and changed the archive version by date. E.g., version 2024.10.16 is downloaded around that date.

Note that gcamfaostat v1.0.0 used a version of FAOSTAT data downloaded in Fall 2022, which produced data in GCAM v7.0.

The GCAM model (GCAMv5.3 NDC) and input files used to conduct Iyer & Ou, et al. 2022 (Ratcheting of climate pledges needed to limit peak global warming )

1. The model needs to be compiled using third-party libraries (see https://jgcri.github.io/gcam-doc/gcam-build.html). Source code has been included in the GCAMv5.3_NDC/csv
2. Default GCAM input files have been included in GCAMv5.3_NDC/input/gcamdata/xml
3. Additional input files for NDC scenarios have been included in GCAMv5.3_NDC/input/NDC_Ratchet_policy
4. A sample configuration_NDC_sample.xml has been included in GCAMv5.3_NDC/exe with detailed setup instruction
