Single-Blind Detection, Localization, and Quantification of Methane Emissions Using Continuous Path-Integrated Column Measurements

Autor: Nathan Blume, Timothy Pernini, Jeremy Dobler, T. Zaccheo, Doug McGregor, Clay Bell

The GreenLITE™ emission monitoring system detected, located, and quantified methane (CH4) emissions from a series of single-blind controlled releases with no prior knowledge of timing, locations, or release rates. System performance was evaluated a

A new exponentially decaying error correlation model for assimilating OCO-2 column-average CO2 data using a length scale computed from airborne lidar measurements

Autor: David F. Baker, Emily Bell, Kenneth J. Davis, Joel F. Campbell, Bing Lin, Jeremy Dobler

Publikováno v: Geoscientific Model Development. 15:649-668

To check the accuracy of column-average dry air CO2 mole fractions (XCO2) retrieved from Orbiting Carbon Observatory (OCO-2) data, a similar quantity has been measured from the Multi-functional Fiber Laser Lidar (MFLL) aboard aircraft flying undernea

Evaluation of the WRF-UCM mesoscale model and ECMWF global operational forecasts over the Paris region in the prospect of tracer atmospheric transport modeling

Autor: Jinghui Lian, Lin Wu, François-Marie Bréon, Grégoire Broquet, Robert Vautard, T. Scott Zaccheo, Jeremy Dobler, Philippe Ciais

Publikováno v: Elementa: Science of the Anthropocene, Vol 6, Iss 1 (2018)

The quantification of CO2 emissions from cities using atmospheric measurements requires accurate knowledge of the atmospheric transport. Complex urban terrains significantly modify surface roughness, augment surface energy budgets, and create heat is

A New Laser Based Approach for Measuring Atmospheric Greenhouse Gases

Autor: Jeremy Dobler, Michael Braun, Nathan Blume, T. Scott Zaccheo

Publikováno v: Remote Sensing, Vol 5, Iss 12, Pp 6284-6304 (2013)

In 2012, we developed a proof-of-concept system for a new open-path laser absorption spectrometer concept for measuring atmospheric CO2. The measurement approach utilizes high-reliability all-fiber-based, continuous-wave laser technology, along with

Estimating Oil Sands Emissions using Horizontal Path-Integrated Column Measurements

Autor: T. Scott Zaccheo, Nathan Blume, Jeremy Dobler, Timothy G. Pernini

Publikováno v: Atmospheric Measurement Techniques, Vol 15, Pp 225-240 (2022)

Improved technologies and approaches to reliably measure and quantify fugitive greenhouse gas emissions from oil sands operations are needed to accurately assess emissions and develop mitigation strategies that minimize the cost impact of future prod
