Overview

About

Maintained by Ranjit Kumar PaulCRAN page ↗

Computes rainfall anomaly indices and a standardised temperature anomaly from monthly or annual precipitation and temperature data supplied by the user. The rainfall indices are the Rainfall Anomaly Index (RAI; Van Rooy, 1965), the Modified Rainfall Anomaly Index (MRAI) and the Standardized Rainfall Anomaly Index (SRAI) of Ekpetere (2025) doi:10.1016/j.jenvman.2025.124160, the Simplified Standardized Precipitation Index (SSPI) of Raziei (2021) doi:10.1016/j.jhydrol.2021.126761, and the Standardized Precipitation Index (SPI; McKee et al., 1993). The temperature anomaly is a z-score computed within each calendar month. All indices are computed group-wise, so the user can stratify by any combination of spatial units (state, district, grid cell) and calendar month, and each value can be classified into a descriptive severity class.

Install

R (CRAN)Fedora (COPR)openSUSE (OBS)

install.packages("ClimateAnomaly", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-ClimateAnomaly

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-ClimateAnomaly

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
