Adapts the Regional Frequency Analysis to Air Temperature R package NSTempRFA version 0.2.0 Adapts the index-flood technique to extreme air temperature data. The package uses the additive approach proposed in Martins et al. (2022) <doi:10.1590/1678-4499.20220061> and adapt it to climate change conditions through the use of nonstationary parametric distributions.
