دراسة الارتباط بين توزيع بيانات القمر الصناعي توماس و رصدات ظاهرة الأتربة على المحطات السطحية

Abstract EN

From the link study between the TOMS satellite aerosol data and the dust data of meteorological surface's stations located at north of the Kingdom of Saudi Arabia, it was found that the following cases, very violent, violent and class "02", which are classified according to satellite data, are more categories where there were all kinds of phenomena of dust monitored by the ground stations, and there are more classifications, which include abundant changes in the dew point temperature and atmospheric pressure.

While the following cases, very weak, weak and class "00" are categories where there are at least one type of dust phenomena associated with a little change in the dew point temperature and atmospheric pressure.

The study pointed to that, the northern of Saudi Arabia is affected, in general, with less severe types of the dust phenomenon and that the time ratio of severe types affecting is about 28% of study period with no more than one station monitor the phenomenon.

This study found that there is good agreement between the dust classifications based on the TOMS satellite data and the distribution of the dust phenomena monitoring the meteorological surface stations, so if any of the phenomena somewhere in north of Saudi Arabia Categorized as a violent or widespread based on TOMS data we expect, in this time, with a lot of confidence that the surface stations located near the place of classification will monitor more violent types of phenomena.
