Quantifying snowfall from orographic cloud seeding. [PDF]

Proc Natl Acad Sci U S A, 2020
Significance Cloud seeding to increase winter snowpack in mountains has traditionally been evaluated using precipitation gauges and target/control statistics leading mostly to inconclusive results. Here, an approach employing radar and gauges is used to quantify snowfall by first isolating radar returns that are unambiguously the result of ...

Precipitation formation from orographic cloud seeding. [PDF]

Proc Natl Acad Sci U S A, 2018
Throughout the western United States and other semiarid mountainous regions across the globe, water supplies are fed primarily through the melting of snowpack. Growing populations place higher demands on water, while warmer winters and earlier springs reduce its supply. Water managers are tantalized by the prospect of cloud seeding as a way to increase

Response of Cloud and Precipitation Properties to Seeding at a Supercooled Cloud‐Top Layer

Earth and Space Science, 2022
To accurately identify ideal operating conditions for scientific cloud seeding and to collect evidence of the effects of seeding, a set of three flights, with figure‐8‐like paths, was designed for supercooled liquid water detection.

Microwave synthesized and laser activated hyaluronic/polyacrylate/basil seed cloud seeding glaciogenic/hygroscopic nanocomposite [PDF]

Scientific Reports
Cloud seeding is a technique used for weather modification, but the commonly used material, silver iodide, has environmental concerns. In response to this concern, we report a biocompatible hyaluronate/polyacrylate/basil seed nanocomposite was ...

Structured dataset of reported cloud seeding activities in the United States (2000–2025) using an LLM [PDF]

Scientific Data
Cloud seeding, a weather modification technique used to increase precipitation, has been practiced in the western United States since the 1940s. However, comprehensive datasets are not currently available to analyze these efforts. To address this gap, we

How frequent is natural cloud seeding from ice cloud layers ( < −35 °C) over Switzerland? [PDF]

Atmospheric Chemistry and Physics, 2021
Clouds and cloud feedbacks represent one of the largest uncertainties in climate projections. As the ice phase influences many key cloud properties and their lifetime, its formation needs to be better understood in order to improve climate and weather ...
