FTS Open Path Measurements Around Munich (EW3C.1)
Presenter: Jia Chen, Technische Universität Munchen

We present a novel way of monitoring urban carbon emissions using measurements obtained by MUCCnet. The fully autonomous sensor network consists of 5 solar-tracking FTIR spectrometer systems and measures the column-averaged GHG concentrations in Munich.

Total Carbon Column Observing Network (TCCON) (EW3C.2)
Presenter: Debra Wunch, University of Toronto

The TCCON is a global network of ground-based remote sensing observatories that measure atmospheric absorption spectra to retrieve atmospheric trace gas abundances of greenhouse gases. The TCCON supports satellite validation and carbon cycle science research.

Compact QCL Absorption Spectrometer for Balloon-borne Water Vapor Measurements in the Upper Atmosphere (EW3C.3)
Presenter: Manuel Graf, Empa

We present a lightweight mid-IR spectrometer for accurate measurements of the H2O concentration in the upper troposphere and lower stratosphere (UTLS) aboard meteorological balloons.

Remote Detection of Chemical Plumes Using Swept-Wavelength External Cavity Quantum Cascade Lasers (EW3C.4)
Presenter: Mark Phillips, University of Arizona

External cavity quantum cascade lasers with wavelength sweep rates above turbulence time scales enable fast and sensitive standoff detection of multiple chemicals in outdoor plume releases and high-explosive detonations.

28 km Open Path Dual-Comb Spectroscopy (EW3C.5)
Presenter: Kevin Cossel, National Institute of Standards and Technology

Dual-comb laser absorption spectroscopy is demonstrated over a 28 km open path over an urban environment. Path averaged concentrations of CO2, H2O and CH4 are retrieved despite significant turbulence induced link loss.
