Daniel Rosenfeld is an Israeli atmospheric scientist and academic. He is a Professor Emeritus at The Hebrew University as well as an Adjunct Professor at Texas A&M University, Nanjing University, and Wuhan University.[1]

Rosenfeld's research has explored how aerosols influence cloud processes and precipitation, demonstrating that while particulate air pollution suppresses rainfall from shallow clouds, it intensifies deep convection, increasing lightning, hail, tornado severity, and hurricane expansion and weakening, whereas large sea salt aerosols mitigate these effects. His scholarly contributions include more than 300 publications in journals including Science, Nature, PNAS, Earth-Science Reviews, and Geophysical Research Letters.[2]

Rosenfeld served as a Lead Author of the chapter 'Water Cycle Changes' in the 6th IPCC Assessment Report[3][1] and co-chaired the Aerosol-Cloud-Precipitation Climate (ACPC) international initiative.[4] He has received the Friendship Award, E.M.T Award, Kaufman Award,[5] and Verner Suomi Medal.[6]

Education

[edit]

Rosenfeld completed his academic training at The Hebrew University, earning a B.Sc. in Geology in 1977, followed by an M.Sc. in 1980 and a Ph.D. in 1986 in Atmospheric Sciences.[7]

Career

[edit]

Rosenfeld began his career as a Teaching Assistant at The Hebrew University between 1977 and 1986 and subsequently assumed the position of Postdoctoral Research Fellow at NASA/GSFC, a role he retained until 1988. At The Hebrew University, Rosenfeld held multiple appointments, including as a Lecturer from 1988 to 1991, a Senior Lecturer from 1991 to 1998, an Associate Professor from 1998 to 2001, and a Professor from 2001 to 2020. He has served as an Adjunct Professor at Texas A&M University since 2014, at Nanjing University since 2018,[8] and at Wuhan University since 2020. He has been a Professor Emeritus at The Hebrew University since 2020.[1]

Research

[edit]

Rosenfeld's research interests have focused on weather modification and climate change, with a specific emphasis on the impact of aerosols and particulate pollution on clouds, precipitation, and Earth's energy budget. In 2000, he revealed that urban and industrial air pollution significantly suppressed rain and snow by reducing cloud particle size, inhibiting droplet coalescence, and preventing ice precipitation formation, leading to widespread changes in regional precipitation patterns.[9] Later, in collaboration with Ramanathan, Crutzen, and Kiehl, he demonstrated that human-made aerosols weakened the hydrological cycle by altering solar radiation, atmospheric temperature, and precipitation patterns, ultimately affecting freshwater availability and environmental sustainability.[10] In a study on Amazon forest fires, he found that smoke reduced cloud droplet size, delayed precipitation, intensified storms, and transported pollutants into the upper troposphere, disrupting atmospheric circulation, the water cycle, and climate systems.[11]

Among his other works, Rosenfeld revealed that aerosols influence precipitation by either suppressing or enhancing rainfall, as their dual role—dictated by radiative and cloud condensation nuclei (CCN) effects—modulates cloud development, longevity, and the precipitation.[12] He further documented that human activities have led to an increase in CCN and Ice Nuclei (IN), altering cloud microphysics, influencing precipitation processes, and affecting the atmospheric water cycle, weather patterns, and climate dynamics.[13] Moreover, along with Gehui Wang and others, he established that persistent sulfate formation exacerbated severe haze by promoting nitrate and organic matter accumulation; however, stringent NH₃ and NO₂ controls effectively disrupted this process, offering a viable strategy for mitigating air pollution in heavily polluted regions.[14]
