Item Extreme and intense precipitation(World Climate Research Programme, 2021) Roca, Rémy; Masunaga, Hirohiko; Alexander, LisaThe availability of numerous gridded precipitation products and the importance of the question of extreme precipitation have led to a number of new findings. Over land, this intercomparison generally emphasizes that global space-based precipitation products show the potential for climate-scale analyses of extremes to serve as a complementary source to in situ gridded data, while reanalysis should be used with caution. Over the ocean, the spread among the products of extreme intensity is larger than over land. The global characteristics of the representation of precipitation extremes are found at the regional scale as well. Yet, the magnitude and the behavior among the products show significant regional disparities that are more and more carefully documented in the literature. With these caveats, the new generation of satellite products are successfully used for process-oriented studies and climate models evaluation.Item The Joint IPWG/GEWEX Precipitation Assessment(World Climate Research Programme, 2021) Roca, Rémy; Haddad, Ziad S.; Akimoto, Fumie F.; Alexander, Lisa; Behrangi, Ali; Huffman, George; Kato, Seiji; Kidd, Chris; Kirstetter, Pierre-Emmanuel; Kubota, Takuji; Kummerow, Chris; L’Ecuyer, Tristan; Levizzani, Vincenzo; Maggioni, Viviana; Massari, Christian; Masunaga, Hirohiko; Schröder, Marc; Tapiador, Francisco J.; Turk, Francis J.; Utsumi, NobuyukiThis report reviews the current state of precipitation products, and includes assessments of sub-daily global satellite precipitation products, discussions of various climate applications of precipitation products, and deliberations on emerging directions and the future of precipitation products.
