When in Rome: The GMAO Participates in the 5th International Conference on Reanalysis

One of major themes at the GMAO is “reanalysis”, a long-term, model-based analysis of multiple observational datasets using a fixed data assimilation system. exterior shot of venue This was the focus of the 5th International Conference on Reanalysis (ICR5) held in Rome, Italy between November 13 and 17, 2017.

28th CERES Science Team Meeting and GMAO

The 28th CERES Science Team Meeting was held at GSFC on September 26–28, 2017, and the GMAO had a strong presence at the meeting. CERES (Clouds and the Earth's Radiant Energy System) is an instrument that was first launched on the TERRA satellite in 1999 and currently flies on Aqua and Suomi-NPP. CERES measures both the solar-reflected and Earth-emitted radiation from the top of the atmosphere.

GMAO supports first ASPIRE launch

The GMAO provided customized forecast support for the launch of a suborbital rocket from NASA's Wallops Flight Facility in support of the Advanced Supersonic Parachute Inflation Research Experiment (ASPIRE) on October 4 at 6:45am EDT. The mission team used data from the GEOS-FP system to help determine the precise moment to trigger the deployment of the parachute, which is being tested for use in future missions to Mars, including the Mars 2020 Rover mission.

The Recipe for an Active Atlantic Hurricane Season

In order to have an active hurricane season in the Atlantic, three key components — sea surface temperature, wind structure, and atmospheric pressure — have to be just right.

The Great American Solar Eclipse as Seen by the GMAO

To experience the great eclipse of 2017, various members of the GMAO traveled to different locations around the USA: Florida, Nebraska, Tennessee, Wyoming, and South Carolina. Others chose to watch the event locally, either close to home or on campus at GSFC, where they enjoyed the events on the Goddard Mall.

Eclipse Across America: GEOS Cloud Predictions

GMAO's Bill Putman created plots made from the GEOS FP model runs to suggest the areas of the US with and without predicted significant cloudiness at 1800hrs UTC on 21 August 2017. These plots were updated twice each day.

3D Carbon Dioxide Visualization Appears in Prestigious Festival

A scientific visualization of 3D global carbon dioxide data is appearing at this week’s SIGGRAPH 2017 Computer Animation Festival in Los Angeles, California. From hundreds of submissions the visualization is among only 25 videos selected for the prestigious Electronic Theater. The first screening is tonight at the Los Angeles Convention Center.

GMAO at Goddard’s 2017 Science Jamboree

Once a year many of Goddard Space Flight Center’s different departments and missions come together to exhibit their latest research and discoveries. At the Global Modeling and Assimilation Office (GMAO) table, in the Earth Science wing, visitors got a sneak peek of an outreach product in development, the Data Cube, which provides six examples of MERRA-2 data products. Visitors were also able to view a 15-minute presentation featuring highlighted GMAO research.

MERRA-2: Data for You

In conjunction with the Global Modeling and Assimilation Office (GMAO), the American Meteorological Society has released a Special Collection of journal articles about NASA’s Modern-Era Retrospective Analysis for Research and Applications, Version 2 (MERRA-2). Coordinated by Mike Bosilovich in the GMAO, this Special Collection provides insight into the overall performance of MERRA-2, while addressing key research questions.

Gi-Kong Kim retires after a long and illustrious career at NASA and GMAO

Congratulations to Gi-Kong Kim on his retirement!

Clara Draper takes a position at NOAA's Earth System Research Laboratory

Congratulations to Clara Draper, who will be moving to NOAA's Earth System Research Laboratory in Boulder, CO. In her new position, Clara will be working with the Cooperative Institute for Research in Environmental Sciences (CIRES) to develop and test next-generation ensemble-based data assimilation capabilities for NOAA's global NWP system.

Summary of GMAO Field Campaign Support for 2016

GMAO supported nine different field campaigns in 2016, which implied an extremely busy year for the Operational Production. The geographical extent of these campaigns spanned the entire globe, from the North Pole to the South Pole, with numerous locations in between. The environments of scientific study were primarily the oceans and the atmosphere.

NASA's GMAO Makes A Strong Presence at AGU Fall 2016 Meeting

NASA's Global Modeling and Assimilation Office made a strong presence at this year's American Geophysical Union Fall Meeting held in San Francisco from December 12-16. GMAO scientists gave a total of 13 talks and 17 poster presentations on topics ranging from cutting-edge assimilations of CO2 satellite data to the performance of the GEOS Seasonal Forecasting System in predicting the 2015/2016 El Niño, and associated teleconnection patterns at high latitudes.

Some major upgrades are imminent for the GMAO's GEOS Forward-Processing (GEOS FP) system : we intend to put them into production on January 24, 2017.

Supercomputing Conference Hyper for GMAO’s Hyperwall Presentations!

Four members of the GMAO, Tom Clune, Bill Putman, Ben Auer, and Matt Thompson, attended SC16 supercomputing conference in Salt Lake City, Utah, 13-18 November 2016. Each gave a Hyperwall presentation at the NASA Booth, showcasing GMAO work.

AMSR Unified Rainfall Team begins to use GEOS FP-IT

The list of GEOS Forward Processing for Instrument Teams (FP-IT) data users keeps expanding. The Advanced Microwave Scanning Radiometer (AMSR) Unified Rainfall team is the latest to join the list. The team started to access the GEOS FP-IT data at GES DISC in October, 2016.

2016 Earth Expeditions: ORACLES

Southern Africa produces almost a third of the world’s vegetative burning, which sends smoke particles up into the atmosphere, where they eventually mix with stratocumulus clouds over the southeastern Atlantic Ocean. The Observations of Clouds above Aerosols and their Interactions (ORACLES) study is investigating how these particles impact the stratocumulus clouds, which play a key role in both regional and global surface temperatures and precipitation, in order to help improve current climate models.
