pantanal_climate

This repository contains code and documentation for downloading and processing temperature and relative humidity for the Pantanal region using ERA5-Land datasets accessed through the Climate Data Store (CDS). The extraction is performed using the KrigR R package, which enables spatial interpolation of ERA5-Land data at high resolution.

Contents

• pantanal_climate.Rmd: R Markdown file containing code to:
  • Authenticate with the CDS API
  • Define the spatial and temporal extent
  • Download and process temperature and dew point data from ERA5-Land
  • Calculate relative humidity
  • Output and organize cleaned data
• pantanal_climate.html: Rendered HTML document with code.
• Recommended folder structure under the data/ directory for reproducibility.

Prerequisites

1. CDS API Access

To download data from the CDS, you must:

• Register an account
• Accept the terms of use
• Follow the CDS API setup instructions

2. R Packages

Install the necessary R packages:

if(!require("devtools")) install.packages("devtools")
if(!require("KrigR")) devtools::install_github("https://github.com/ErikKusch/KrigR")

install.packages(c("tidyverse", "sf", "terra", "slider"))

Directory Structure

Ensure your working directory has the following layout:

pantanal_climate/
├── 01_get climate data.Rmd
├── 01_get climate data.html
├── pantanal_climate_data.Rproj
└── data/
    ├── raw/         # Raw data with locations and dates of collections
    ├── interim/     # Intermediate processed files from ERA5-Land
    └── processed/   # Final clean datasets

You can create the directory structure in R:

dir.create("data/raw", recursive = TRUE)
dir.create("data/interim", recursive = TRUE)
dir.create("data/processed", recursive = TRUE)

Usage

1. Clone this repository:

git clone https://github.com/pcarc1/pantanal_climate.git
cd pantanal_climate

2. Open RProject file (pantanal_climate_data.Rproj), then open pantanal_climate.Rmd in RStudio and run all code chunks.

3. Output files will be saved in the appropriate data/ subfolders.
