Airborne and ground-based observations of a weekend effect in ozone, precursors, and oxidation products in the California South Coast Air Basin

Journal Article

Airborne and ground-based measurements during the CalNex (California Research at the Nexus of Air Quality and Climate Change) field study in May/June 2010 show a weekend effect in ozone in the South Coast Air Basin (SoCAB) consistent with previous...

Gravitational separation of Ar/N-2 and age of air in the lowermost stratosphere in airborne observations and a chemical transport model

Journal Article

Accurate simulation of atmospheric circulation, particularly in the lower stratosphere, is challenging due to unresolved wave–mean flow interactions and limited high-resolution observations for validation. Gravity-induced pressure gradients lead to a...

Toward constraining regional-scale fluxes of CO2 with atmospheric observations over a continent: 1. Observed spatial variability from airborne platforms

Journal Article

[1] We analyze the spatial variability of CO₂ measurements from aircraft platforms, including extensive observations acquired over North America during the CO₂ Budget and Rectification Airborne (COBRA) study in 2000. The COBRA data set is unique in its...

Measuring fluxes of trace gases at regional scales by Lagrangian observations: application to the CO2 Budget and Rectification Airborne (COBRA) study

Journal Article

[1] We present a general framework for designing and analyzing Lagrangian-type aircraft observations in order to measure surface fluxes of trace gases on regional scales. Lagrangian experiments minimize uncertainties due to advection by measuring...

Methane airborne measurements and comparison to global models during BARCA

Journal Article

Tropical regions, especially the Amazon region, account for large emissions of methane (CH₄). Here, we present CH₄ observations from two airborne campaigns conducted within the BARCA (Balanço Atmosférico Regional de Carbono na Amazônia) project in the...

Airborne observations of methane emissions from rice cultivation in the Sacramento Valley of California

Journal Article

Airborne measurements of methane (CH4) and carbon dioxide (CO2) were taken over the rice growing region of California's Sacramento Valley in the late spring of 2010 and 2011. From these and ancillary measurements, we show that CH4 mixing ratios were...

Nitrous oxide (N2O) emissions from California based on 2010 CalNex airborne measurements

Journal Article

Nitrous oxide (N₂O) is an important gas for climate and for stratospheric chemistry, with a lifetime exceeding 100 years. Global concentrations have increased steadily since the 18th century, apparently due to human-associated emissions, principally from...
