A thorough examination of Land Use and Land Cover (LULC) changes is advantageous for environmental assessment and land management. The principal catalyst of this phenomena is human activity, particularly population expansion and the demand for increased urbanization. In this paper, Landsat imagery acquired from 2014 to 2022 was utilized to detect and classify alterations in land cover in Kirkuk City area. The Landsat images of the research region were analyzed employing two supervised classification techniques: the Maximum Likelihood Classification (MLC) algorithm and the Neural Network (NN) classification. Six specific signature classifications were chosen for categorization: water, bare land, soil, farm land, urban, and vegetation. The overall accuracy assessments of the MLC exceeded that of NN. The research findings revealed the substantial increase in agriculture and urban areas in Kirkuk city during the past few years. On the other hand, bare land and soil-covered regions has been reduced. These changes in land use are attributed to economic and population growth. The results of this study can significantly aid future urban planners in promoting sustainable urban development and protecting rural areas from random urbanization.

Acid rain is linked to the process of urbanization and industrialization and harms buildings. This study aims to evaluate acid rain in Kirkuk city using GIS-based spatial analysis, mathematical statistical modeling, and laboratory tests and examine the harmful effects on the city buildings and human health. Precipitation ranges were determined based on Theisen’s polygon techniques. The methodology is based on two types of laboratory measurements of specific rainfall samples within the city for the period of January 2021 to March 2022. Geographical Information Systems GISs were used to verify the spatial distribution and quantity of precipitation data in the study area. Remote sensing RS was also used for mapping rainfall rates during the study period. According to spatial distribution maps, the acidity level of rain was classified as (least acidic) ranging between (5.5 and 5.6). Specifically in the southern and south-eastern parts of the study area. Besides, spatial distributions have been presented with high accuracy with 95% and 83% accuracy ratings in 2021 and 2022, respectively. Thus, we attempt to offer some useful guidelines for conserving buildings so that they are preserved for a long time. RS and GIS techniques are best suited for estimating and modeling rainfall data characteristics.

Even though there are expert monitoring and assessment stations in large cities, air quality monitoring and measurement have a high cost and face significant issues. Data on air pollution can be acquired from remote sensing satellites for large areas and at a reasonable expense to compensate for monitoring stations on the ground. This research presented a method for retrieving PM10 from Moderate Resolution Imaging Spectroradiometer (MODIS) satellite Aerosol Optical Thickness (AOT) records. The study depends on a previously established equation to retrieve PM10 over Malaysia in September 2014. In Contrast Reduction Technique, we used Aerosol Robotic Network AERONET AOT to define the reference. The conversion factors, representing the relationship between AOT and PM10 satellite columns, were determined using a mathematical approach. The size and type of aerosol, relative humidity, and boundary layer height vary globally and seasonally, thus the AOT–PM10 relationship fluctuates spatially and temporally. The conversion factor was then applied to the MODIS image to predict the surface level of PM10 concentrations in micrograms via cubic meter (μg/m3). Moreover, the achieved correlation coefficient R2 of calculated PM10 based on ground truth data was equal to 0.92. Based on the results obtained from the thematic maps, PM10 levels are significantly higher in specific cities such as Kuala Lumpur and Johor. Where PM10 ranged from (26.5 to 72) µg/m3, while AOT values were between (0.12 and 0.83). It raises concerns about the environmental health threats and their relationship to air quality in these regions as a research topic. © 2023 National Authority of Remote Sensing & Space Science

According to World Health Organization (WHO) estimates and based on a world population review, Iraq ranks tenth among the most air-polluted countries in the world. In this study, the authors tried to evaluate the outdoor air of Kirkuk City north of Iraq. The authors relied on two types of data: field measurements and remotely sensed data. Fifteen air quality points were determined in the study region representing the monthly average measurements implemented for the one-year dataset. Geographic information systems (GIS) based geo-statistic and geo-processing techniques have been applied to collected data. Spatial distribution data related to Air Quality Index (AQI), and Particulate Matter (PM10 and PM2.5) were obtained by mapping collected records. Remotely sensed data of PM2.5 were analyzed and compared with the collected data. Health impacts were assessed per each air pollutant determined in the study. Spatial distribution maps revealed the hazardous air type in the study area. Overall AQI ranged between 300 and 472 µg/m3 referring to unhealthy, very unhealthy, and hazardous classes of pollution. Also, PM10 ranged between 300 and 570 µg/m3 indicating the same class of air pollution from unhealthy to hazardous. While PM2.5 ranged between 40 and 60 µg/m3 which represents unhealthy air for sensitive persons and unhealthy air. The remotely sensed data revealed different air types for the study period ranging from 14.5 to 52.5 µg/m3 represented in moderate and unhealthy air for sensitive persons. Significant correlations were obtained where the mean local R2 (coefficient of determination) was obtained as 0.83. The assessed data were within high air pollution that requires immediate intervention for controlling causes and eliminating their effects

The main objective of this paper is to calculate the perturbations of tide effect on LEO's satellites (GEO11, GEO12, GEO13, NOAA2 and NOAA3). In order to achieve this goal, the changes in the orbital elements which include the semi major axis (a) eccentricity (e) inclination (i), right ascension of ascending nodes (Ω), and fifth element argument of perigee (ω) must be employed. In the absence of perturbations, these element remain constant. The results show that the effect of tidal perturbation on the orbital elements depends on the inclination of the satellite orbit. The variation in the ratio (Δi/i) decreases with increasing the inclination of satellite, while it increases with increasing the time. © 2020 University of Baghdad-College of Science.

The uniform expansion in the population of Kirkuk governorate increases the interest in constructing new hospitals. Their development must suit many factors such as contamination, distance to health centers, financial constraints, social inconvenience and, temporal restrictions. Thus, this work is used an analytic hierarchy process (AHP)-based Geographical information system (GIS) to choose and determine the suitable site for new hospitals construction and their services. It is performed throughout two stages, the first one is to determine the availability land for constructing a new hospital based on many factors such as: distances from landfill, existing hospitals, main roads, railways, water bodies as well as erasing the residential area. These factors are represented the constraint area. The second stage is to select land suitability via the suitability process is achieved based on various factor decision weights. The proposed method provided a useful reference for hospital managers and researchers to construct a normalize d selecting to locate a new hospital facility. the AHP has presented their ability to select the suitability map of the site selection of hospitals with high accuracy. © 2019 IEEE.

The dynamic evolution of sun-synchronous orbits at a time interval of 20 years is considered. The numerical motion simulation has been carried out using the Celestial Mechanics software package developed at the Institute of Astronomy of the University of Bern. The dependence of the dynamic evolution on the initial value of the ascending node longitude is examined for two families of sun-synchronous orbits with altitudes of 751 and 1191 km. Variations of the semimajor axis and orbit inclination are obtained depending on the initial value of the ascending node longitude. Recommendations on the selection of orbits, in which spent sun-synchronous satellites can be moved, are formulated. Minimal changes of elements over a time interval of 20 years have been observed for orbits in which at the initial time the angle between the orbit ascending node and the direction of the Sun measured along the equator have been close to 90° or 270°. In this case, the semimajor axis of the orbit is not experiencing secular perturbations arising from the satellite’s passage through the Earth’s shadow
