SCISAT‐1, also known as the Atmospheric Chemistry Experiment (ACE), is a Canadian satellite mission for remote sensing of Earth's atmosphere. It was launched into low Earth circular orbit (altitude 650 km, inclination 74°) on 12 Aug. 2003. The primary ACE instrument high spectral resolution (0.02 cm −1 ) Fourier Transform Spectrometer (FTS) operating from 2.2 to 13.3 μm (750–4400 ). features dual spectrophotometer MAESTRO with wavelength coverage 285–1030 nm and 1–2 nm. A pair filtered CMOS...

This paper presents extensive {bias determination} analyses of ozone observations from the Atmospheric Chemistry Experiment (ACE) satellite instruments: ACE Fourier Transform Spectrometer (ACE-FTS) and Measurement Aerosol Extinction in Stratosphere Troposphere Retrieved by Occultation (ACE-MAESTRO) instrument. Here we compare latest data products ACE-FTS ACE-MAESTRO with coincident nearly 20 satellite-borne, airborne, balloon-borne ground-based instruments, analysing volume mixing...
Abstract. Vertical profiles of NO2 and NO have been obtained from solar occultation measurements by the Atmospheric Chemistry Experiment (ACE), using an infrared Fourier Transform Spectrometer (ACE-FTS) (for NO2) ultraviolet-visible-near-infrared spectrometer, MAESTRO (Measurement Aerosol Extinction in Stratosphere Troposphere Retrieved Occultation). In this paper, quality ACE-FTS version 2.2 1.2 data are assessed other (HALOE, SAGE II, III, POAM SCIAMACHY), stellar (GOMOS), limb (MIPAS,...
This paper presents long-term intercomparisons (2003–2017) between ozone and NO2 measured by the Optical Spectrograph Infra-Red Imager System (OSIRIS) Atmospheric Chemistry Experiment (ACE) satellite instruments, ground-based instruments at Polar Environment Research Laboratory (PEARL), near Eureka, Nunavut, Canada (80∘N, 86∘W). The include four zenith-sky differential optical absorption spectroscopy (DOAS) two Fourier transform infrared (FTIR) spectrometers, a Brewer spectrophotometer....
Abstract. The Atmospheric Chemistry Experiment (ACE) mission was launched in August 2003 to sound the atmosphere by solar occultation. Water vapour (H2O), one of most important molecules for climate and atmospheric chemistry, is key species provided two principal instruments, infrared Fourier Transform Spectrometer (ACE-FTS) MAESTRO UV-Visible spectrometer (ACE-MAESTRO). first instrument performs measurements on several lines 1362–2137 cm−1 range, from which vertically resolved H2O...
We show that the dayside MOPITT retrievals in lower troposphere can provide useful information on surface sources of atmospheric CO over Indian subcontinent. find at 850 hPa localized enhancements subcontinent, which correlate with similar seen tropospheric NO 2 columns from SCIAMACHY instrument. In particular, high concentrations Indo‐Gangetic basin and some prominent cities are captured lower‐tropospheric spring. averaging kernels (normalized to take into account absorber amounts layers)...
We have examined the influence of synoptic processes on distribution atmospheric CO as observed by Measurements Pollution in Troposphere (MOPITT) satellite instrument. In MOPITT data, large horizontal gradients CO, coherent at scale, been observed. The concentration varies rapidly much 50–100% across distances ∼100 km, forming distinct boundaries distribution. These can last one to several days and span 600–1000 km. On average, such events were daily images once every 3–4 over North America...
Near‐infrared (NIR) atmospheric extinction profile observations from the Atmospheric Chemistry Experiment (ACE) Imager and Measurements of Aerosol Extinction in Stratosphere Troposphere Retrieved by Occultation (MAESTRO) are presented, illustrating impact Kasatochi volcanic eruption August 2008 on aerosol loading upper troposphere lower stratosphere subsequent months. In September 2008, profiles NIR show a significant increase relative to each previous four Septembers (2004–2007). The...
Abstract. The first three Canadian Arctic ACE validation campaigns were held during polar sunrise at Eureka, Nunavut, Canada (80° N, 86° W) from 2004 to 2006 in support of the (Atmospheric Chemistry Experiment) satellite mission. Three or four zenith-sky viewing UV-visible spectrometers have taken part each campaigns. differential slant column densities and vertical ozone NO2 these instruments been compared following methods Working Group NDACC (Network for Detection Atmospheric Composition...
Hot smoke tests were carried out in the site of four atriums heights over 32 m a big shopping complex. The objective was to evaluate performance mechanical exhaust systems installed. This is required while inspecting fire service installations as specified local codes. Testing procedures followed those Australian Standard with slight modifications. A 2 MW methanol pool agreed tests. It set up six trays test chamber for reducing radiation effect adjacent combustibles. main testing criterion...
Abstract. This paper presents extensive validation analyses of ozone observations from the Atmospheric Chemistry Experiment (ACE) satellite instruments: ACE Fourier Transform Spectrometer (ACE-FTS) and Measurement Aerosol Extinction in Stratosphere Troposphere Retrieved by Occultation (ACE-MAESTRO) instrument. The instruments operate mid-infrared ultraviolet-visible-near-infrared spectral regions using solar occultation technique. In order to continue long-standing record measurements space,...

Abstract. In the fall of 2006, Measurements Of Pollution The Troposphere (MOPITT) instrument on Terra satellite observed an extremely high Carbon monoxide (CO) concentration over Indonesia. This extreme event was caused by huge fire activity during 2006 El Nino event. From our comparison with other CO pollution events Indonesia similar and moderate events, we conclude that activity, which large-scale in this region, probably amplified increase frequency and/or intensity lightning a feedback...
