Abstract A very devastating and long duration wildfire episode occurred in Greece near Athens during 20-25 July 2018. We have investigated particulate matter PM10 and PM2.5; and selected greenhouse gases such as CO2, NO2, SO2, and CH4 which are known to be generated due to the burning of coal, vegetation, and gasoline. There are significant changes in carbon dioxide, methane and carbon monoxide based on the simulations with the chemical transport model. Further, we have checked the ionospheric perturbations during 20-25 July 2018, using the global positioning system (GPS) derived total electron content (TEC) maps over Greece. We have used detrended TEC data to observe the fluctuation in the ionospheric total electron during the presented event. We found that strong ionospheric perturbations have appeared during these events in coincident location to the lower atmospheric anomalies observed in the troposphere and stratosphere. A possible mechanism of the generation of the Atmospheric Gravity Waves (AGW) and Earth’s surface-atmosphere-ionosphere coupling has been discussed. Detrended atmospheric gases/particulate matter density and detrended GPS TEC shows similar variation trend, however, ionospheric changes show significant time delay. This indicates the energy from forest fire region penetrates into ionosphere through the lower atmosphere and gradually triggers fluctuations in the density of the atmospheric elements as well as ionospheric TEC.

由于岩石层-大气-电离层耦合，希腊上空的森林火灾引发了电离层扰动

摘要 2018 年 7 月 20 日至 25 日期间，希腊雅典附近发生了一场破坏性非常大且持续时间长的野火事件。我们调查了颗粒物 PM10 和 PM2.5；以及特定的温室气体，例如 CO2、NO2、SO2 和 CH4，这些气体是已知因燃煤、植被和汽油而产生的。基于化学传输模型的模拟，二氧化碳、甲烷和一氧化碳发生了显着变化。此外，我们使用全球定位系统 (GPS) 得出的希腊总电子含量 (TEC) 地图检查了 2018 年 7 月 20 日至 25 日期间的电离层扰动。我们使用去趋势的 TEC 数据来观察当前事件期间电离层总电子的波动。我们发现在这些事件中，强烈的电离层扰动出现在与对流层和平流层中观测到的较低大气异常重合的位置。已经讨论了产生大气引力波 (AGW) 和地球表面-大气-电离层耦合的可能机制。去趋势的大气气体/颗粒物密度和去趋势的 GPS TEC 显示出类似的变化趋势，但是，电离层变化显示出显着的时间延迟。这表明森林火灾区的能量通过低层大气渗透到电离层，逐渐引发大气元素密度和电离层TEC的波动。已经讨论了产生大气引力波 (AGW) 和地球表面-大气-电离层耦合的可能机制。去趋势的大气气体/颗粒物密度和去趋势的 GPS TEC 显示出类似的变化趋势，但是，电离层变化显示出显着的时间延迟。这表明森林火灾区的能量通过低层大气渗透到电离层，逐渐引发大气元素密度和电离层TEC的波动。已经讨论了产生大气引力波 (AGW) 和地球表面-大气-电离层耦合的可能机制。去趋势的大气气体/颗粒物密度和去趋势的 GPS TEC 显示出类似的变化趋势，但是，电离层变化显示出显着的时间延迟。这表明森林火灾区的能量通过低层大气渗透到电离层，逐渐引发大气元素密度和电离层TEC的波动。
