An assessment of the stray light in 25 years of Dobson total ozone data at Athens, Greece
Summary: We investigated the susceptibility of the Dobson spectrophotometer No. 118 to stray-light interference. The monochromatic-heterochromatic stray light derived by Basher’s model was used in order to evaluate the specific instrumental parameters which determine if this instrument suffers from this problem or not. The results obtained indicate that the Athens Dobson instrument appears to have an insignificant stray-light error.

Extended and refined multi sensor reanalysis of total ozone for the period 1970–2012
Summary: The ozone multi-sensor reanalysis (MSR2) is a multi-decadal ozone column analysis for the period 1970-2012 based on all available ozone column satellite datasets, surface Brewer-Dobson observations and a data assimilation technique with detailed error modelling. The latest total ozone retrievals of 15 different satellite instruments are used: BUV-Nimbus4, TOMS-Nimbus7, TOMS-EP, SBUV-7, -9, -11, -14, -16, -17, -18, -19, GOME, SCIAMACHY, OMI and GOME-2.

Consistent satellite XCO2 retrievals from SCIAMACHY and GOSAT using the BESD algorithm
Summary: Long-term data sets of global atmospheric carbon dioxide concentrations based on observations from different satellite instruments may suffer from inconsistencies originating from the use of different retrieval algorithms. This issue has been addressed by applying the Bremen Optimal Estimation DOAS retrieval algorithm to SCIAMACHY and TANSO-FTS observations. Detailed comparisons with TCCON and CarbonTracker show good consistency between the SCIAMACHY and TANSO-FTS data sets.

A switchable reagent ion high resolution time-of-flight chemical ionization mass spectrometer for real-time measurement of gas phase oxidized species: characterization from the 2013 southern oxidant and aerosol study
Summary: A novel configuration of the Aerodyne high resolution time-of-flight chemical ionization mass spectrometer (HR-TOF-CIMS) as a switchable reagent ion (SRI) HR-TOF-CIMS is presented and described along with data collected at the Southern Oxidant and Aerosol Study (SOAS) during the summer of 2013. Formic acid and other relevant species are presented, and they exhibit a strong diel cycle being rapidly produced during the day and dropping below the limit of detection at night.

MISR empirical stray light corrections in high-contrast scenes
Summary: We address mirroring, blurring, and background radiometric anomalies in the MISR standard Level 1 product empirically by comparing nadir-view near-infrared MISR with simultaneous MODIS images in high-contrast scenes. These anomalies affect aerosol optical depth and aerosol type results, especially over dark ocean scenes with broken cloud. We validate the corrections in all MISR channels by comparing multi-angle research retrievals with 1100 simultaneous surface sun photometer observations.

High-resolution continuous-flow analysis setup for water isotopic measurement from ice cores using laser spectroscopy
Summary: Here we present an experimental setup for water stable isotopes continuous flow measurements. It is the first continuous flow laser spectroscopy system that is using off-axis integrated cavity output spectroscopy (analyzer manufactured by LGR) in combination with an evaporation unit to continuously analyze sample from an ice core. The isotopic water analyzer setup used during the 2013 RICE ice core processing campaign achieved measurements with high precision and high temporal resolution.

Methane emission estimates using chamber and tracer release experiments for a municipal waste water treatment plant
Summary: This study presents two methods for estimating methane emissions from a waste water treatment plant (WWTP) along with results from a measurement campaign at a WWTP in Valence, France. We show that the tracer release method is suitable to quantify facility emissions, while the chamber measurements, provide insights into individual processes. We confirm that the open basins are not a major source of CH4 on the WWTP but that the pretreatment and sludge treatment are the main emitters.

Profiling wind and greenhouse gases by infrared-laser occultation: results from end-to-end simulations in windy air
Summary: This paper discusses simulation results of a newly developed line-of-sight wind retrieval algorithm expanding an existing simulation framework that includes the retrieval of thermodynamic variables and greenhouse gases in the upper troposphere/lower stratosphere region. The underlying mission concept further develops the radio occultation technique (i.e. satellite remote sensing technique scanning the atmosphere with high vertical resolution) employing microwave and infrared-laser signals.

An automatic collector to monitor insoluble atmospheric deposition: application for mineral dust deposition
Summary: An automatic collector (CARAGA) has been developed to monitor insoluble atmospheric deposition in remote areas with a large autonomy. It is used to sample total (dry and wet) deposition on Frioul Island in the western Mediterranean Basin over which Saharan dust can be transported and deposited. To quantify the mineral dust mass in deposition samples, a weighing and ignition protocol is used. Two years of continuous deposition measurements performed on a weekly sampling basis are presented.
