SCISAT-1, also known as the Atmospheric Chemistry Experiment, is a satellite mission for remote sensing of the Earth's atmosphere, launched on 12 August 2003. The primary instrument on the satellite is a 0.02 cm(-1) resolution Fourier-transform spectrometer operating in the mid-IR (750-4400 cm(-1)). We describe the approach developed for the retrieval of(More)
[1] Elevated levels of tropical tropospheric ozone (O3) and carbon monoxide (CO) and decreased water (H2O) vapor were observed by the Tropospheric Emission Spectrometer (TES) in the region of Indonesia and the eastern Indian Ocean during the coincident positive phases of the El Niño Southern Oscillation (ENSO) and Indian Ocean Dipole (IOD) in late 2006.(More)

Remote measurements of trace gas profiles from nadir-viewing instruments are often retrieved and/or reported on a fine grid containing more levels than the number of independent pieces of information in the measurement. Such profiles contain a priori information, which complicates interpretation. For scientific analyses of these data it is desirable to move(More)

From January to March 2005, the Atmospheric Chemistry Experiment high resolution Fourier transform spectrometer (ACE-FTS) on SCISAT-1 measured many of the changes occurring in the Arctic (50–80 N) lower stratosphere under very cold winter conditions. Here we focus on the partitioning between the inorganic chlorine reservoirs HCl and ClONO2 and their(More)
The effect of rate of perfusion, volume, pH of the perfusate, and partition coefficient of the drug on the rate of in situ nasal absorption in rats was examined. The studies showed that the rate constant for the nasal absorption of phenobarbital was independent of the rate of perfusion above a value of 2 mL/min. The nasal absorption of benzoic acid was(More)
[1] The Tropospheric Emission Spectrometer (TES) is unique in providing multi-year coincident tropospheric profiles of CO, O3 and H2O. TES data show large differences in these gases over Indonesia and the eastern Indian Ocean in October–December 2006 relative to 2005. In 2006, O3 was higher by 15–30 ppb (30–75%) while CO was higher by >80 ppb in October and(More)
Breathing motion severely degrades the quality of magnetic resonance images (MRI) of the thorax and upper abdomen and interferes with the acquisition of quantitative data. To minimize these motion effects, we built an MRI compatible ventilator for use in animal studies. Solid state circuitry is used for controlling ventilation parameters. The ventilator can(More)
