This dataverse provides

• a global database of water vapor atmospheric rivers (ARs) based on multiple reanalysis products;
• a global database of aerosol ARs based on the MERRA-2 reanalysis;
• the AR detection code; and
• codes for a suite of AR model evaluation metrics.

Water vapor AR detection is based on the tARget algorithm originally introduced in Guan and Waliser (2015, JGR; Version 1), refined in Guan et al. (2018, JHM; Version 2), and further enhanced in Guan and Waliser (2019, JGR; Version 3) with tracking capability.

Aerosol AR detection is largely based on the tARget algorithm originally introduced in Guan and Waliser (2015, JGR) for water vapor ARs, with a few modifications as described in Chakraborty et al. (2022, ACP).

For a list of studies using the AR data or the AR detection algorithm/code from this dataverse, see here.
