Fan and Meng Develop New Machine Learning Snowfall Detection Algorithm
October 18, 2021
ESSIC/CISESS scientists Huan Meng and Yongzhen Fan have recently developed a new machine learning snowfall detection (SD) algorithm, based on eXtreme Gradient Boosting (XGB). The algorithm was developed for the Advanced Technology Microwave Sounder (ATMS) onboard NPP and NOAA-20 as well as the MHS/AMSU-A onboard Metop-A, Metop-B, Metop-C and NOAA-19.

Using Seasonal Terrestrial Water Storage Forecasts to Predict African Vegetation Activity
October 1, 2021
ESSIC scientists Kimberly Slinski, Christa Peters-Lidard, and Abheera Hazra are co-authors on a new study that discusses terrestrial water storage (TWS), a metric that provides important information on terrestrial hydroclimate and may have value for seasonal forecasting because of its strong persistence.
Improving Flood and Drought Management in Agricultural River Basins
October 1, 2021
ESSIC Post-doctoral Associate Natthachet Tangdamrongsub is a co-author on a new study in Water Policy that aims at the solutions to mitigate flood and drought damage to agriculture. For this international paper, Tangdamrongsub worked alongside researchers from the Rajamangala University of Technology Thanyaburi in Thailand and the IHE Delft Institute for Water Education in the Netherlands.
UV Surface Reflectance from OMPS Nadir Mapper (NM) Radiance—Simulation and Assimilation
October 1, 2021
ESSIC/CISESS scientists Christopher Grassotti and Xingming Liang are co-authors in a recently published study that documents the first ultraviolet radiance assimilation for atmospheric ozone in the troposphere and stratosphere. The paper, titled “Experimental OMPS Radiance Assimilation through One-Dimensional Variational Analysis for Total Column Ozone in the Atmosphere”, was published in Remote Sensing and includes co-authors from the NOAA/NESDIS Center for Satellite Applications and Research.
Remote Sensing of Evapotranspiration for Global Drought Monitoring
October 1, 2021
ESSIC/CISESS scientists Li Fang, Jifu Yin, Mitchell Schull, and Jicheng Liu collaborated on a chapter in Global Drought and Flood: Observation, Modeling, and Prediction titled “Remote Sensing of Evapotranspiration for Global Drought Monitoring”.
Coral Reef Watch Enhances Four-Month Coral Bleaching Outlook and Develops New Methodology for Prototype Coral Reef Resilience Product
October 1, 2021
This month, NOAA Coral Reef Watch (CRW) completed two product development milestones, to implement an improved Four-Month Coral Bleaching Heat Stress Outlook and develop the methodology for a new, prototype Coral Reef Resilience product.
UMD, ESSIC Researchers Find Evidence of New CFC Production
September 7, 2021
In 1986, chlorofluorocarbons (CFCs), chemical compounds known to break down ozone in the atmosphere, were banned by the Montreal Protocol. This led to an immediate rapid decline in emissions. However, recent studies have shown that CFC-11 emissions have increased, suggesting a contribution from eastern Asia.
Performance of NOAA Satellite-based Precipitation Products During Tropical Storm Fred
September 7, 2021
On August 18, 2021, the western part of North Carolina suffered a catastrophic flash flood caused by Tropical Storm Fred. As part of a NOAA/STAR precipitation validation project, CISESS science team Malar Arulraj, Veljko Petković, Ralph Ferraro, and Huan Meng evaluated the performance of different satellite-based precipitation products during this event using Multi-Radar/Multi-Sensor (MRMS) observations.
