For the first time, sulfur dioxide concentration was monitored between 2005 and 2016 over Iran which is among the countries with a high SO2 emission rate in the world. To that end, SO2 column concentration at Planetary Boundary Layer (PBL) from Ozone Monitoring Instrument (OMI) was analyzed. OMI is a sensor onboard the Aura satellite which can measure daily SO2 concentration on the global scale...

Several validation studies have shown a notable overestimation of the clear sky ultraviolet (UV) irradiance at the Earth’s surface derived from satellite sensors such as the Total Ozone Mapping Spectrometer (TOMS) and the Ozone Monitoring Instrument (OMI) with respect to groundbased UV data at many locations. Most of this positive bias is attributed to boundary layer aerosol absorption that is ...

Recent work shows a tendency to use programming languages specific to the social aspects of multi-agent systems, for example in programming norms that agents ought to follow. In this paper, we introduce a simple and elegant normative programming language called NPL and show its operational semantics. We then define a particular class of NPL programs that are suitable for programming Organisatio...

Retrievals of tropospheric nitrogen dioxide (NO2) from the Ozone Monitoring Instrument (OMI) are subject to errors in the treatments of aerosols, surface reflectance anisotropy, and vertical profile of NO2. Here we quantify the influences over China via an improved retrieval process. We explicitly account for aerosol optical effects (simulated by nested GEOS-Chem at 0.667 long. × 0.5 lat. and c...

The Ozone Monitoring Instrument (OMI) onboard NASA’s Aura satellite has been providing global observations of the ozone layer and key atmospheric pollutant gases, such as nitrogen dioxide (NO2) and sulfur dioxide (SO2), since October 2004. The data products from the same instrument provide consistent spatial and temporal coverage and permit the study of anthropogenic and natural emissions on lo...

This study aimed to quantify the microdamage cortical bone of different thickness and maximum insertion torque during orthodontic miniscrew implant (OMI) placement with without a pilot hole. Forty-five porcine specimens were prepared thicknesses 1.5, 2 2.5 mm. Ten per had hole drilled prior an OMI, remaining 15 OMI inserted. Sequential staining was used identify damage caused by preparation sur...

A novel heterozygous non-synonymous mutation and a novel polymorphism in OMI/HTRA2 locus have been associated with Parkinson's disease (PD) in a German population. In an attempt to replicate these results in an independent population, we analyzed the entire coding region of OMI/HTRA2 in a series of 644 North American PD cases with both young- and late-onset disease and in 828 North American neu...

A novel Hilbert-twin (H-twin) method is introduced as an alternative method for the computation of the resonant frequency for exponentially damped free decays embedded in noise. We also present the comparison among the following methods used to compute the dynamic elastic modulus in solids: the parametric OMI (Optimization in Multiple Intervals), the Yoshida-Magalas (YM) interpolated discrete F...
