English Abstract

The countries of the Middle East, including Iraq, is expected to suffer from frequent dust storms.

In the last year, the dust storms were more than 14 times which led to the accumulation of about 100 million tons of dust, this due to the encroachment of the desert, the lack of agricultural areas, the low rainfall and lack of water in the Tigris and the Euphrates caused by the construction of large dams built in Turkey and Syria.

The present study is an attempt to overcome and quantities the problem of the large number of frequency of dust storms and the areas that generated and then identifying these areas in order to be held by the agricultural areas, as has been the adoption of many of the techniques and methods of processing image in remote sensing and geographic information systems and linking them together to identify those areas in Iraq or the neighbors, especially the northern and north-west wind of the fact that Iraq is in the northern and north - western most days of the year.

The use of satellite images that were obtained from the free sites and with resolution 250 meter is nearly sufficient to identify areas of the emergence of these storms to the fact that areas of these storms is too big and can cover Iraq and neighboring countries at one time.

Image processing that has been converted to include the coordinates of image maps, and then classify these images and the separation of components using the software programs that available free at the university.

Research has included the use of images from the satellite (MODIS) with quality (Aqua) and (Terra) with the assembly of the amount of dust, these storms, it was determining the values of size and density of the soil and the amount (> 10μm) and (ρ = 1.58 mg/m3) respectively , note that this soil has collected from the University of Baghdad during a sandstorm brief summary on 22/02/2010.

We calculated the total dust quantity on July 2010, because this month is the most higher month temperature in the year and it was about 50 thousand ton of dust in each dust storm.

to extract all the results and information that obtained from the operations account amounts that the soil is expected calculated annually for these storms and to determine the threshold line density of this dust in the air.

Finally, we must develop a system to monitor these storms, depending on the capacity of scientific instruments of modern used in the countries of the world and its establishment in Iraq, including (Aerosol Robotic Network (AERONET)) located in different regions from north to south, which can give high accuracy in the calculation of the thickness of the atmosphere and that taking data and daily throughout the year and perform calculations with the assistance of satellite images available for free .
