Version 6 Level-4 SMAP Soil Moisture and Carbon Data Products Released

The Soil Moisture Active Passive (SMAP) project released Version 6 of the Level-4 Soil Moisture and Carbon data products. The key change in the new version is the improved precipitation forcing, which is now primarily based on IMERG products. The data are generated at the NASA Global Modeling and Assimilation Office (610.1) and available from the NASA National Snow and Ice Data Center.

Vice President Harris Visits NASA's Goddard Space Flight Center

Accompanied by Senator Chris Van Hollen and NASA Administrator Bill Nelson, Vice President Kamala Harris visited NASA's Goddard Space Flight Center. At her visit, Vice President Harris heard presentations describing how the nation's space program studies climate change and provides crucial information to understand our planet's changes and their impacts on our lives. Lesley Ott (610.1) presented an overview of NASA climate change research and a hyperwall presentation highlighting the impacts of climate change as observed from space and the role of Earth system models in helping communities prepare. Ott was joined by Pam Melroy from NASA Headquarters, who introduced NASA's Earth Science Division, and Christian Braneon (611) from the Goddard Institute for Space Studies. Braneon provided examples of communities using satellite data in their environmental decision making. The event concluded with NASA Administrator Nelson and Goddard biospheric scientist Lola Fatoyinbo (618) presenting the first light Landsat-9 image.

GMAO Analyzes Record North American Heat Dome

An extreme heatwave dominated the circulation over the North-Western section of North America in late June and early July 2021. This extreme meteorological event was covered extensively by the media on account of its links to climate change and its drastic impact on mortality, especially in western Canada. A complete picture of this event is being built using the GEOS models and satellite observations, spanning the dynamical processes that caused the event, and its subsequent impacts on air quality, fires, and surface moisture and energy budgets.

Rolf Reichle (610.1) was recognized as one of AGU’s Outstanding Reviewers of 2020 by the Chief Editor of Reviews of Geophysics.

Andrews Discusses Greenland Ice Sheet Melt in The Washington Post

Lauren Andrews (610.1) was quoted in The Washington Post's Capital Weather Gang feature about last week's Greenland ice sheet melt.

Dr. Randal Koster Named Recipient of 2021 William Nordberg Memorial Award for Earth Science

Photo of RandyWe are thrilled to announce the selection of Dr. Randy Koster as the 2021 William Nordberg Memorial Award for Earth Science winner.

Dr. Koster is being recognized for research that has provided unique insights in the field of hydrology, combining modeling efforts with space-based observations, putting GSFC at the forefront of Earth science.

Dr. Koster has worked at NASA GSFC since September of 1987, first as a member of the Hydrological Sciences Branch, and currently as a member of the Global Modeling and Assimilation Office (GMAO). His early work focused on the analysis of global water isotope geochemistry. Most of his tenure at GSFC, though, has been dedicated to two research thrusts: (i) the development of improved treatments of land surface physics for Earth system models, and (ii) the analysis of interactions between the land and atmosphere, using these models. He has examined many questions regarding land-atmosphere feedback, including: Can knowledge of soil moisture conditions at the beginning of a seasonal weather forecast improve the forecast? Can we find evidence in the observational record that variability in land surface states has an effect on rainfall, air temperature, and other atmospheric variables? He has coordinated multi-institutional analyses of land-atmosphere feedback for two components of the World Climate Research Programme. He serves on the Soil Moisture Active Passive (SMAP) Science Team, focusing on making sure that SMAP satellite-based soil moisture data is useful for climate studies and other applications.

With the advent of the GMAO in 2003, Dr. Koster was given the responsibility of coordinating the land surface modeling activities at GSFC into a single land surface modeling system. This ever-evolving system is used extensively by the GMAO and is available for use by the NASA community.

Randy will be presented with the William Nordberg Memorial Award during a future Scientific Colloquium that will be scheduled once we are all back on Center.

GMAO Releases MERRA-2 Climate Statistics Supplementary Dataset

The GMAO is pleased to announce the public release of the MERRA-2 Climate Statistics supplementary dataset.
