Introduction

The input data for REMIND is prepared by a set of pre-processing routines that take the data from original sources (e.g. IEA, GTAP, PWT...), execute additional calculations and convert it to the required REMIND parameter format.

The input files are setup in the config file config/default.cfg. The regional resolution of the run is set in the by

cfg$regionmapping

(default setting: regionmapping <- "config/regionmappingH12.csv"). Based on the regional resolution and the input data revision

cfg$revision

the name of the needed input data is constructed. It is checked whether those input data are already available. If not they are automatically downloaded from /p/projects/rd3mod/inputdata/output/ and distributed.

The prepared input data is a compressed tar archive file ".tgz", which can be opened with software such as 7-Zip, or in terminal by tar and untar commands.

Lokal Input Data

If you like to get the input data on your local machine you need to copy your ssh key (/home/[your_cluster_user_name]/.ssh/id_dsa) to your computer and adjust your local .Rprofile by adding the following line:

options(remind_repos=list("scp://cluster.pik-potsdam.de/p/projects/rd3mod/inputdata/output"=list(username="[your_cluster_user_name]",ssh_private_keyfile="[path_to_your_local_copy_of_your_key]")))

If your key is password-protected you have to remove this by using an empty passphrase:

ssh-keygen -p
-> path to id_dsa
-> empty passphrase

It is recommended to first copy the existing key (e.g. id_dsa into id_dsa-local) and remove the passphrase of this copy and copy it to your machine.

If you plan to run REMIND not with the default regional resolution you have to take care that REMIND starts from a gdx with the correct regional resolution. Either you can use one from an older run with the corresponding regional resolution or you can construct a new gdx with the correct regional resolution from a gdx in a different regional resolution by using the function gdx_rename from the package (gdx) (e.g. gdx_rename("input.gdx",set_name="all_regi",c(REF="RUS",CAZ="ROW",...,MEA="MEA",USA="USA"))).

Adding New Input Data

The input data for REMIND are generated by using the R-libraries moinput and madrat (https://github.com/pik-piam/madrat). While moinput contains all calculations tailored to REMIND-input-data, the package madrat provides the general wrapper functions and helpful tools. For further information read the vignettes part of the R-packages.
