Application of biochar as a soil amendment could be significant approach for carbon sequestration to possibly control climate change energy and environmental sustainability. However, more studies are needed in number research areas, including the development clean materials free any harmful substances, before this implemented at global scale. In study, water-extractable substances were tested their potential effects on growth aquatic photosynthetic microorganisms both blue–green alga...
Abstract. This paper presents an analysis of observations methane and its two major isotopologues, CH3D 13CH4, from the Atmospheric Chemistry Experiment (ACE) satellite between 2004 2013. Additionally, atmospheric chemistry is modeled using Whole Community Climate Model (WACCM). ACE retrievals extend 6 km for all isotopologues to 75 12CH4, 35 CH3D, 50 13CH4. While total concentrations retrieved agree well with model, values δD–CH4 δ13C–CH4 show a bias toward higher δ compared model...
Abstract The distributions of the four most abundant isotopologues and isotopomers (N 2 O, 15 NNO, N NO, NN 18 O) nitrous oxide have been measured in Earth's stratosphere by infrared remote sensing with Atmospheric Chemistry Experiment (ACE) Fourier transform spectrometer. These satellite observations provided a near‐global picture O isotopic fractionation. relative abundances heavier species increase altitude latitude as air becomes older. heavy are enriched 20–30% upper even more over...
ACE (also known as SCISAT) is making a comprehensive set of simultaneous measurements numerous trace gases, thin clouds, aerosols and temperature by solar occultation from satellite in low earth orbit.A high inclination orbit gives coverage tropical, mid-latitudes polar regions.The primary instrument high-resolution (0.02 cm -1 ) infrared Fourier Transform Spectrometer (FTS) operating the 750-4400 region, which provides vertical distribution meteorological variables pressure.Aerosols clouds...

The 3 µm region of ethane, propane and propene contains a number vibrational modes dominated by various C-H stretches.Transmission spectra for these hydrocarbons have been obtained at high resolution (0.005 cm -1 ) elevated temperatures (up to 773 K).The integrated absorption cross sections over the isolated are calibrated those from Pacific Northwest National Laboratory (PNNL) in order obtain an effective pressure sample.With Jovian Infrared Auroral Mapper (JIRAM on Juno) due arrive Jupiter...
Atmospheric isotopologues are useful tracers of dynamics and chemistry can be used to constrain budgets gases in the atmosphere.The Chemistry Experiment (ACE) routinely measures vertical profiles over 35 molecules 20 via solar occultation from a satellite low Earth orbit.The primary instrument is an infrared Fourier transform spectrometer with spectral range 750 -4400 cm -1 resolution 0.02 .ACE began taking measurements 2004 still active today.This talk focuses on isotopic CH 4 , CO, CO 2 N...
