Satellite Monitoring Of Ozone Layer Changes In The Atmosphere Of Iran
Abstract
Considering the vital importance of the ozone layer and the rising course of increasing its destructive factors in recent decades, the necessity of studying the ozone layer in order to know its state in the atmosphere of Iran has become more recent. In recent years, several techniques and techniques have been used to monitor this vital gas in the atmosphere of the planet. Meanwhile, the use of satellite data has become widespread because of the availability and availability of features such as spatial, temporal and spatial resolution. The study also uses ozone data collected by the AIRS based on the AQUA satellite, which provides an opportunity to study the process of Ozone changes in the atmosphere of all parts of the world, including Iran. The relevant data were extracted from the https://disc.gsfc.nasa.gov/datasets/AIRS3STM_006 website with the NetCDF format, with one-day and one-day temporal resolution and a 1° x 1° spatial resolution during the 15-year statistical period (2003 - 217) ArcGIS and Grads software was analyzed, visualized, analyzed. The results indicate that annual ozone has dropped in the atmosphere of Iran. Among the seasons, the highest and lowest ozone levels occurred in the spring and autumn seasons, and the highest and lowest monthly ozone levels were observed in March and October, respectively. In terms of location, moving from the south to the north, it is approximately uniformly increased by the amount of ozone, so that the maximum total ozone (TOC) in Pars Abad plain (318 Dobson) and its lowest value in an interconnected area Provinces of Hormozgan, Kerman and Fars, and part of Southeastern Iran (283 Dobson). The maximum ozone concentration (ozonosphere) is also evident at an altitude of 27-40 km.
