Kumar Named a 2022 Arthur S. Fleming Award Recipient

Photo of Dr. Sujay KumarCongratulations to Dr. Sujay Kumar for his 2022 Arthur S. Fleming Award. Named in honor of Arthur S. Flemming, awardees are recognized for excellence in federal service. Dr. Kumar was recognized in the category of Applied Science and Engineering. Dr. Kumar researches Earth remote sensing measurement and modeling within NASA Goddard Space Flight Center’s Hydrological Sciences Lab. For the past 20 years, he has led the development of the Land Information System (LIS) modeling system, which is used worldwide in applications of water resources management, food security assessments, and flood and drought monitoring and prediction.

Liu Ground Water Paper is a 2022 Top 25 Earth, Environmental, and Planetary Sciences Article

Pang-Wei Liu’s (617/SSAI) publication is awarded as one of the Top 25 most downloaded papers for 2022 in Nature Communications in the category of Earth, Environmental, and Planetary Sciences. The paper is titled “Groundwater depletion in California’s Central Valley accelerates during megadrought.” Rajat Bindlish (617) and Matt Rodell (610) are co-authors. The paper uses GRACE and GRACE-FO data to estimate groundwater variations in Central Valley, California, during 2003-2021. The study quantified groundwater loss rates during the period and found that the groundwater depletion is accelerating.

Lab Members Attend UN Water Conference

Sujay Kumar (617) and Perry Oddo (617/SSAI) attended the UN water conference at the United Nations Headquarters in New York as part of the NASA team within the US Government delegation. This is the first major international conference on water held by the UN in 46 years with more than 10,000 people attending.

The Hydrological Sciences Laboratory examines the role of water in the Earth system. Laboratory researchers strive to better understand, quantify, and analyze the hydrological cycle and to measure hydrological processes in order to improve prediction of the response of global hydrology to anthropogenic and/or natural climate change.

Special emphasis is placed on land surface hydrological processes and their interactions with the atmosphere. Laboratory scientists develop remote-sensing and modeling techniques to investigate how the various components of the hydrological cycle interact over a broad range of spatial and temporal scales.
