The Potsdam Institute for Climate Impact Research (PIK) Atmospheric River Trajectories (PIKART) catalog records atmospheric rivers globally, from 1940 to 2023, at 0.5° spatial resolution and 6-hour temporal resolution. It was introduced in the following publication:

Vallejo‐Bernal, S. M., Braun, T., Marwan, N., & Kurths, J. (2025). PIKART: A comprehensive global catalog of atmospheric rivers. Journal of Geophysical Research: Atmospheres, 130(15), e2024JD041869. DOI: 10.1029/2024JD041869

PIKART's algorithm is coded in Python and Bash and compiled on Foote, the high-performance computer of the Potsdam Institute for Climate Impact Research in Germany.

This repository contains the scripts to compile version 1.0 of PIKART.
