“…A positive effect on the surface precipitation amounts was shown by the double ratio methodology (Pokharel, Geerts, Jing, Friedrich, Ikeda, & Rasmussen, 2017). Although the impacts of cloud seeding on season‐long precipitation values have been estimated in many experiments (Gabriel, 1999; Manton et al., 2011; Rasmussen et al., 2018), there are two remaining issues in the verification of the impacts of seeding on ground precipitation. One is the matter of how to clearly identify the time and location of the seeded cloud in the natural cloud system; the other is the major challenge of accurately detecting increased surface precipitation (Flossmann et al., 2018).…”
