Users of G-WADI linked PERSIANN precipitation data and information downloaded almost 19 terabytes of data in 2018. This continued a five-year trend of annual doubling of data downloaded that began in 2013.
The data products and systems were designed by, and are served by, the University of California, Irvine's Center for Hydrometeorology and Remote Sensing. The majority of the data downloaded was from the real-time precipitation product PERSIANN-CCS. The “climate data record" product, PERSIANN-CDR and the original PERSIANN product constituted most of the rest of the data downloads. In additio... Read More

In October 2018, after over a decade of effort, a Drought Atlas for Latin America and Caribbean was released by UNESCO-IHP and the Water Center for Arid and Semi-Arid Zones in Latin America and the Caribbean (CAZALAC). The Atlas uses Regional Frequency Analysis (RFA), based on a statistical method called L-moments, to assist drought planners and decision-makers in both public and private sectors.
During an African regional workshop on “Climate Change Risk, Vulnerability Assessment and Early Warning for Africa”, held on 13-16 June 2017 at the AGRHYMET Centre in Niamey, Niger, the need had been... Read More
