Title:  Chemical Data Assimilation and Analog-Based Uncertainty Quantification to Improve Short-term Air Quality Predictions Over the U.S.

Speaker:  Lucca Delle Monache

Abstract: One of the key tools used by decision makers across the U.S. to protect the public from adverse health effects caused by poor air quality (AQ) is the National Oceanic and Atmospheric Administration (NOAA) / National Centers for Environmental Prediction (NCEP) operational AQ forecasting system. To enhance this decision-making activity, this project funded by the National Aeronautics and Space Administration (NASA), aims to improve the accuracy of NOAA/NCEP short-term predictions of ground-level ozone and particulate matter less than 2.5 µm in diameter (PM2.5) and to provide reliable quantification of their uncertainty, by exploiting NASA Earth Science Data with chemical data assimilation and analog-based approaches. The three main project objectives are:

  • To improve the initialization of the NOAA/NCEP operational AQ system, which is based on the Community Multiscale AQ (CMAQ) model, through chemical data assimilation of satellite retrieval products with the Community Gridpoint Statistical Interpolation (GSI) system. GSI is being used to assimilate retrievals of aerosol optical depth from the NASA Aqua/Terra Moderate Resolution Imaging Spectroradiometer (MODIS).
  • To considerably improve the CMAQ deterministic predictions and reliably quantify their uncertainty with analog-based post-processing methods applied to the CMAQ deterministic predictions.
  • To extrapolate deterministic and probabilistic point-based predictions to a two-dimensional grid over the U.S. with a Barnes-type iterative scheme.

Results from the aforementioned objectives will be reported, with a focus on the analog-based techniques, quantifying the developed system performance with a range of metrics for both deterministic and probabilistic predictions of PM2.5 across several hundreds of stations over the U.S.

Outcomes of the Coastal Convective Interactions Experiment and new horizons with the Australian radar network

Abstract: This seminar will present two topics from the Australian observational meteorology research space.

(1) The densely populated coastal regions of eastern Australia contains diverse physical settings that add considerable uncertainty for convection nowcasting, which currently relies primarily upon the analysis of broad-scale meteorology (e.g., synoptic boundaries and air masses). The Coastal Convective Interactions Experiment (CCIE) was coordinated to address these challenges with a focus upon the South East Queensland region of Australia. Major outcomes are presented, including (i) analysis of thunderstorm hotspots drivers using an 18 year radar-derived climatology, and (ii) the critical near surface and boundary layer processes which favour the development of severe convective storms in marginal synoptic environments.

(2) Weather radar is a fundamental remote sensing tool, however, limitations in data access/standards and ongoing changes in technology presents considerable challenges (and opportunities) for the Australia community. Regarding accessibility, a proposed open-access solution for hosting the Australian operational radar archive using modern data standard is presented, drawing upon the success of the NEXRAD dataset. The database architecture, integration with the research community and applications for historical and real-time radar-based services are discussed. Alongside the 2017 arrival of operational dual-pol to the Australian Bureau of Meteorology radar network, the University of Queensland will be coordinating the calibration and verification of radar-based severe hail and wind detection algorithms. This will include both a multi-season field campaign in the South East Queensland region using mobile dual-pol radar, hail disdrometers and mobile wind towers, and a community science initiative to promote hail reporting. Outcomes will be applied to hazard nowcasting and to improving radar-derived hazard climatologies.

Bio: Joshua Soderholm a PhD Graduate from the University of Queensland, Australia and Australian Bureau of Meteorology. His dissertation explored the climatological and meteorological aspects of sea breeze interactions with warm-season thunderstorms in South East Queensland, Australia. As part of the PhD project, Joshua established the UQ-XPOL mobile radar was established and has seen several successful deployments across Australia for both convective and bushfire research. In addition, Joshua has also worked on radar applications for the energy distribution and insurance sectors and is a keen collaborator across operational, industry and amateur meteorology groups.

The Master Plan of the Shagaya Renewable Energy Park in Kuwait
Yousuf Al-Abdulla | Kuwait Institute for Scientific Research, Kuwait City, Kuwait

Kuwait is developing a large (2G) renewable energy facility, including solar and wind, called Shagaya. Kuwait is located on the north end of the Arabian Gulf and experiences the full range of weather conditions through-out the year. The Shagaya facility is located in the desert west of Kuwait city. Several Kuwaitis are visiting NCAR to learn more about renewable power forecasting for the Shagaya facility. This seminar will cover the current plans for renewable energy in Kuwait and highlight areas where they are looking for further collaboration. 

Yousef Al-Abdullah received a B.S. degree in electrical engineering from Arizona State University, Tempe, in 2007 and a M.S. degree in electrical and computer engineering from the Georgia Institute of Technology, Atlanta, in 2009, and in 2016 he earned his Ph.D. in electrical engineering from ASU. As part of his dissertation he investigated constraint relaxation and out-of-market correction practices in electric energy markets. Upon finishing his degree, he returned to the Kuwait Institute for Scientific Research and is part of the Renewable Energy Program within the Energy and Building Research Center.

Paleoclimate reanalysis workshop Oct. 2-3, Boulder, CO
The Last Millennium Reanalysis team invites your participation in its third workshop, to be held Oct 2-3 at the National Center for Atmospheric Research (Mesa Lab) in Boulder, CO. Paleoclimate data assimilation is emerging as a novel tool to understand low-frequency climate dynamics, blending multi-proxy paleoclimate observations with numerical simulations of Earth’s climate.  Previous workshops have investigated the use of proxy system modeling (2015) and modeling stable water isotopes in the climate system (2016). This workshop will share the project’s latest reconstructions and provide a forum to discuss relevant findings on the climate of the Common Era.  The event will focus on validating the approach against complementary datasets and investigations of low-frequency climate dynamics made possible by this framework. The meeting will be followed by a 1-day hackathon on October 4 to provide graduate students and early-career scientists with hands-on training to use the newly available data and code to perform experiments, manipulate the output, and analyze results..  Limited travel support is available for both events, with priority given to junior participants.  Registration and information are available at  Address questions to Loretta Quinn at UCAR (  Early registration for the meeting and the preferred meeting Hotel, the Best Western Plus Boulder Inn, is encouraged.
We look forward to seeing you in Boulder,
-The LMR team (David Anderson, Julien Emil-Geay, Greg Hakim, and Eric Steig)
