Atmospheric CO_2 measurements with a 2 μm airborne laser absorption spectrometer employing coherent detection
Gary D. Spiers,Robert T. Menzies,Joseph C. Jacob,Lance E. Christensen,Mark W. Phillips,Yonghoon Choi,Edward V. Browell +6 more
TL;DR: Airborne measurements of CO(2) column abundance conducted during two 2009 campaigns using a 2.05 μm laser absorption spectrometer provide insight into the capabilities of the IPDA method for both airborne measurements and future global-scale CO( 2) measurements from low Earth orbit pertinent to the NASA Active Sensing of CO (2) Emissions over Nights, Days, and Seasons mission.
Journal ArticleDOI

TL;DR: In this article, high-resolution in situ CO_2 measurements were conducted aboard the NASA DC-8 aircraft during the ARCTAS/POLARCAT field campaign, a component of the wider 2007-2008 International Polar Year activities.
Journal ArticleDOI

Yonghoon Choi,Stephanie A. Vay,Krishna Prasad Vadrevu,Amber J. Soja,Jung-Hun Woo,S. R. Nolf,Glen W. Sachse,Glenn S. Diskin,Donald R. Blake,Nicola J. Blake,Hanwant B. Singh,Melody A. Avery,Alan Fried,Leonhard Pfister,Henry E. Fuelberg +14 more
TL;DR: For example, during the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT) campaign, high resolution in situ measurements of atmospheric CO2 were made from the NASA DC-8 aircraft during the Intercontinental Chemical Transport Experiment-North America (INTEX-NA) campaign.
Spatiotemporal Variability of Trace Gases in the San Joaquin Valley during DISCOVER-AQ.

Spatio-Temporal Variability of Atmospheric CO2 as Observed from In-Situ Measurements over North America during NASA Field Campaigns (2004-2008)
Yonghoon Choi,Stephanie A. Vay,Jung-Hun Woo,Ki-Chul Choi,Glenn S. Diskin,G. W. Sachse,Krishna Prasad Vadrevu,E. Czech +7 more
TL;DR: In this article, the spatio-temporal distributions of CO2 and CO column values derived from the campaign measurements were examined in conjunction with the emissions inventory and transport histories to aid in the interpretation of the CO2 observations.
