Yuanwei Qin (University of Oklahoma), will discuss, “Dynamics, Driving Factors, and Consequences of Forests, Industrial Plantations, and Woody Plant Encroachment.” This session will highlight recent activities that map and characterize the spatial-temporal dynamics of natural forests, industrial plantations and WPE, including the consequences (e.g., carbon and water cycles) of observed spatial-temporal dynamics of natural forests, industrial plantations, and WPE. Qin’s discussion is scheduled for 8 a.m.- 12:20 p.m., Monday, Dec. 10 in the Poster Hall.

Berrien Moore III (University of Oklahoma), Principal Investigator will present an update on the NASA Earth Venture-2 Mission, GeoCarb which would provide measurements of atmospheric carbon dioxide (CO2), methane (CH4), and carbon monoxide (CO) from geostationary orbit. The GeoCarb mission would deliver daily maps of column integrated mixing ratios of CO2, CH4, and CO over the observed landmasses at a spatial resolution of roughly 5 x 16 km, which will establish the scientific basis for CO2 and CH4 flux determination at ecosystem/weather relevant time and space scale. Dr. Moore’s presentation is scheduled for 1:40 p.m.- 6 p.m., Tuesday, Dec. 11 in the Poster Hall.
WEDNESDAY, DEC. 12, 2018
Chang Qing (University of Oklahoma), will present a study titled, “Characterizing spring phenology of snow-covered forests by vegetation indices, primary productivity and solar-induced chlorophyll fluorescence,” which found that estimation of SOS dates in snow-covered forests need to take into account the effects of snow and temperature on leaf emergence (green-up) and photosynthesis, in addition to vegetation greenness. This presentation is scheduled for 8 a.m. – 12:20 p.m, Wednesday, Dec. 12. in the Poster Hall.
Xiaocui Wu (University of Oklahoma), will discuss spatiotemporal consistency of four gross primary production products and solar-induced fluorescence in response to climate extremes across CONUS in 2012; reporting the impacts of spring warming and summer drought in 2012 on GPP across the contiguous US (CONUS). This study demonstrates the importance of assessing the impacts of different types and timing of climate extremes on GPP, and the need to improve light use efficiency models by incorporating C3 and C4 plant functional types. This discussion is scheduled for 8 a.m. – 12:20 p.m, Wednesday, Dec. 12. in the Poster Hall.
Xiangming Xiao (University of Oklahoma), SIF and Applications Lead joins other leaders in Solar-Induced Fluorescence (SIF) research to host a half-day, technical workshop, “Applications and User Development on Solar-Induced Chlorophyll Fluorescence (SIF) Data Products from Spaceborne Platforms.” The goal of the workshop is to help the community learn about SIF data, highlight tools and resources, and to provide an opportunity to foster growth in the community. The workshop is scheduled for 8 a.m. – 12:20 p.m., Wednesday, Dec. 12 in the Grand Hyatt Hotel - Declaration AB.
Sean Crowell (University of Oklahoma), Deputy PI and Project Scientist will host a flash talk, a 7-minute overview, on the GeoCarb mission. Dr. Crowell’s talk is scheduled for 2:40 p.m., Wednesday, Dec. 12 at the conference Hyperwall.
THURSDAY, DEC. 13, 2018
Xiao-Ming Hu (University of Oklahoma), will present a study titled, “CO2 Dynamical Downscaling in 2016 over the contiguous United States using WRF-VPRM, a weather-biosphere-online-coupled model.” In this study, calibrated VPRM parameters using eddy covariance tower data over North America from Hilton et al [2013] are implemented into WRF-VPRM. WRF-VPRM modeling results indicate biogenic fluxes dominate anthropogenic sources to modulate XCO2 over most area of CONUS except a few metropolitan areas such as Los Angeles in growing season from May to September. This presentation is scheduled for 1:40 p.m. – 6 p.m., Thursday, Dec. 13 in the Poster Hall.
Sean Crowell (University of Oklahoma), will present a talk on "Sensitivity of OCO-2 and In Situ Inversions to Transport, Prior Mean, and Prior Uncertainty: Results from the OCO-2 Model Inter-comparison Project and Beyond." During his presentation, Dr. Crowell will discuss the OCO-2 MIP flux results for the ensemble as a whole, and then proceed to examine the sensitivity of the posterior fluxes with a subset of the modeling approaches that utilize PCTM and TM5 with a suite of prior mean fluxes and prior uncertainties. This presentation is scheduled for 2 p.m. - 4:25 p.m. in room 151B.
FRIDAY, DEC. 14, 2018
Gregory McGarragh (Colorado State University), will discuss the modifications made to the OCO-2/3 heritage retrieval algorithm for application to GeoCARB, additional challenges that must be addressed, and the sensitivity of the retrievals to various sources of uncertainty. He will present results from synthetic scans over the Western Hemisphere that will shed light on retrieved gas concentration errors expected by GeoCarb in both space and in time. McGarrah’s discussion is scheduled for 8 a.m.-12:20 p.m., Friday, Dec. 14 in the Poster Hall.
Helene Peiro (University of Oklahoma), will present on the topic of forest fires throughout the Western Hemisphere. In her talk titled, “10 Years of CO Flux Inversion with Assimilation of MOPITT and IASI Observations - Focus on Forest Fires over Southern and Northern America,” Dr. Peiro will establish her study’s goal to setup a framework of CO emissions from MOPITT and IASI data for the 2008-2016 period with a focus on BB from boreal forests in Canada and tropical forests in Southern America. Dr. Peiro’s presentation is scheduled for 8 a.m.-12:20 p.m., Friday, Dec. 14 in the Poster Hall.
Qingyu Wang (University of Oklahoma), will present a talk titled, “Seasonal Variations in XCO2 Gradient Across Cold Fronts as seen from OCO-2 and WRF-VPRM,” where she will analyze the behavior in column average dry air mole fraction (XCO2) in the vicinity of cold fronts to determine the visibility of these features from space. Using data from the Orbiting Carbon Observatory-2 (OCO-2) for 83 cold frontal cases over the United Sates and neighboring oceans from 2015 to 2017, her study examines difference anomalies across the fronts to establish that the gradient anomalies are significant relative to instrument noise. Ms. Wang’s presentation is scheduled 8 a.m.-12:20 p.m., Friday, Dec. 14 in the Poster Hall.
