|
In this review of the progress of deep learning (DL) for water resources applications, researchers found that DL can help address several major new and old challenges facing research in water sciences.
|
|
|
Researchers developed software for conducting fully Bayesian analysis for general classes of nonstationary Gaussian process models, which are an extremely popular tool in spatial and environmental statistics.
|
|
|
This study shows that the high-resolution version of E3SM is a valuable tool for tropical cyclone-related research as it represents characteristics relevant to predicting hurricane impacts.
|
|
|
|
Through a series of experiments, this study demonstrates that altering the geographic pattern of aerosol emissions leads to different radiative forcing. Most of this forcing arises through aerosol-cloud interactions.
|
|
|
Scientists used climate model simulations and observational data to reveal that since 1950, human-produced greenhouse gases and particulate pollution have influenced global changes in aridity.
|
|
|
Researchers created global maps of soil radiocarbon and carbon mean age and compared estimates with land models, which simulated younger soil and more rapid carbon turnover.

EVENTS & MEETINGS
Do you have a meeting or event to share? Let us know, and we’ll help spread the word. Visit the EESM website for more meetings of interest.
NOAA-DOE Workshop on Precipitation Processes and Predictability: This online community workshop, scheduled from November 30 to December 2, 2020, is jointly organized by the National Oceanic and Atmospheric Administration (NOAA) and DOE in partnership with the U.S. Global Change Research Program (USGCRP) and U.S. Climate Variability and Predictability (CLIVAR). The focus will be on sub-seasonal to multidecadal timescales.
2020 American Geophysical Union (AGU) Fall Meeting: AGU 2020 is scheduled online for December 1 to 17. Be sure to check the website often, as AGU is innovating new approaches to make over 1,000 hours of virtual content available.
2021 American Meteorological Society (AMS) Annual Meeting: The 101st AMS Annual Meeting is scheduled online for January 10 to 14, 2021.
Workshop on Improvement and Calibration of Clouds in Models: This meeting is scheduled for April 12 to 16, 2021 in Toulouse, France.
International Conference on Clouds and Precipitation 2020: This conference is postponed until 2021. The abstract submission system will reopen later this year, so abstracts from the 2020 conference can be revised or new abstracts can be submitted.
