“…The study is focussed on the layer below 16 km altitude and thus only the ascent profiles allow studying this part of the atmosphere. SWIR-balloon is an extended version in the short-wave infrared domain of the IASI-balloon instrument (Té et al, 2002). This instrument is an infrared remote sensing instrument based on a Fourier Transform interferometer.…”

“…In particular we examine the situation on 7 August 2009, which was characterized by unusually large CO abundance in the lower stratosphere. These measurements from 7 August are compared to others performed during the campaign, on 24 August 2009 also by SPIRALE and on 14 August 2009 by the SWIR-balloon (Short Wave Infra Red Fourier transform spectrometer in nadir-looking) instrument (Té et al, 2002). In support of the in situ measurements we use IASI (Infrared Atmospheric Sounding Interferometer) CO satellite data ).…”

Abstract. The SPIRALE and SWIR balloon-borne instruments were launched in the Arctic polar region (near Kiruna, Sweden, 67.9 • N-21.1 • E) during summer on 7 and 24 August 2009 and on 14 August 2009, respectively. The SPI-RALE instrument performed in situ measurements of several trace gases including CO and O 3 at altitudes between 9 and 34 km, with very high vertical resolution (∼ 5 m). The SWIR-balloon instrument measured total and partial column of several species including CO. The CO stratospheric profile from SPIRALE for 7 August 2009 shows some specific structures with large concentrations in the low levels (potential temperatures between 320 and 380 K, i.e. 10-14 km height). These structures are not present in the CO vertical profile of SPIRALE for 24 August 2009, for which the volume mixing ratios are typical from polar latitudes (∼ 30 ppb). CO total columns retrieved from the IASI-MetOp satellite sounder for the three dates of flights are used to understand this CO variability. SPIRALE and SWIR CO partial columns between 9 and 34 km are compared, allowing us to confirm that the enhancement of CO is localised in the stratosphere. The measurements are also investigated in terms of CO:O 3 correlations and using several modelling approaches (trajectory calculations, potential vorticity fields, results of chemistry transport model) in order to characterize the origin of the air masses sampled. The emission sources are qualified in terms of source type (fires, urban pollution) using NH 3 and CO measurements from IASI-MetOp and fires detection from MODIS on board the TERRA/AQUA satellite. The results give strong evidence that the unusual abundance of CO on 7 August is due to surface pollution plumes from East Asia and North America transporting to the upper troposphere and then entering the lower stratosphere by isentropic advection. This study strengthens evidence that the composition of low polar stratosphere in summer may be affected by anthropogenic surface emissions through long-range transport.

“…Numerous flight-proven, validated research instruments exist including the High-resolution Interferometer Sounder (HIS) , the Scanning High-resolution Interferometer Sounder (S-HIS) (Tobin et al 2006), the Airborne Emission Sounder (AES) , the aircraft demonstrator for NASA's Tropospheric Emission Spectrometer (TES), the airborne demonstrators for the Japanese IMG and IASI (Té et al 2002), and the National Polar-Orbiting Operational Environmental Satellite System (NPOESS) Airborne Sounder Testbed-Interferometer (NAST-I) . These instruments were developed to measure accurate, spectrally resolved thermal IR radiances, primarily to deliver temperature and water-vapor profiles.…”

Executive SummaryCurrent GHG-mitigating regimes, whether internationally agreed or self-imposed, rely on the aggregation of self-reported data, with limited checks for consistency and accuracy, for monitoring. As nations commit to more stringent GHG emissions-mitigation actions and as economic rewards or penalties are attached to emission levels, self-reported data will require independent confirmation that they are accurate and reliable, if they are to provide the basis for critical choices and actions that may be required.Supporting emissions-mitigation efforts and agreements, as well as monitoring energy-and fossil-fuel intensive national and global activities would be best achieved by a process of 1. monitoring of emissions and emission-mitigation actions, based, in part, on, 2. (self-) reporting of pertinent bottom-up inventory data, 3. verification that reported data derive from and are consistent with agreed-upon processes and procedures, and 4. validation that reported emissions and emissions-mitigation action data are correct, based on independent measurements (top-down) derived from a suite of sensors in space, air, land, and, possibly, sea, used to deduce and attribute anthropogenic emissions.These data would be assessed and used to deduce and attribute measured GHG concentrations to anthropogenic emissions, attributed geographically and, to the extent possible, by economic sector. The validation element is needed to provide independent assurance that emissions are in accord with reported values, and should be considered as an important addition to the accepted MRV process, leading to a MRV&V process.This study and report focus on attributes of a greenhouse-gas information system (GHGIS) needed to support MRV&V needs. These needs set the function of such a system apart from scientific/research monitoring of GHGs and carbon-cycle systems, and include (not exclusively): the need for a GHGIS that is operational, as required for decision-support; the need for a system that meets specifications derived from imposed requirements; the need for rigorous calibration, verification, and validation (CV&V) standards, processes, and records for all measurement and modeling/data-inversion data; the need to develop and adopt an uncertainty-quantification (UQ) regimen for all measurement and modeling data; and the requirement that GHGIS products can be subjected to third-party questioning and scientific scrutiny.This report examines and assesses presently available capabilities that could contribute to a future GHGIS. These capabilities include sensors and measurement technologies; data analysis and data uncertainty quantification (UQ) practices and methods; and model-based data-inversion practices, methods, and their associated UQ. The report further examines the need for traceable calibration, verification, and validation processes and attached metadata; differences between present science-/research-oriented needs and those that would be required for an operational GHGIS; the development, operation, and maintenance ...

Abstract. Space-borne thermal infrared instruments working in the nadir geometry are providing spectroscopic measurements of species that impact on the chemical composition of the atmosphere and on the climate forcing: H 2 O, CO 2 , N 2 O, CH 4 , CFCs, O 3 , and CO. The atmospheric abundances obtained from the analysis of IMG/ADEOS measurements are discussed in order to demonstrate the potential scientific return to be expected from future missions using advanced infrared nadir sounders. Some strengths and limitations of passive infrared remote sensing from space are illustrated.
