Understanding the files.




File
Content
How to interpret it


Crop.zip
Crop yield data for different dataset (IBGE, Paraná - Deral - and GDHY).
There two types of files. The ones with data from the specific dataset, and the ones startint with "dataset_". The ones that start with "dataset_" contain crop yield data with all database considered in this study.


historic_era5.csv
Contains climate indices calculated for each municipality using ERA5-Land data.
Each column has the name of the index. For more information on how the index was calculated, please, check the publication or reach me: marcosbenso@gmail.com


historic.zip
Contains ERA5-Land data (precipitation, tasmin, tasmax) aggregated at municipal level. Each file is a municipality and the name of the file is the IBGE code for that municipality.
This is a folder with data separated for calculating climate indices.
