dust particles have dangerous impacts on human health, the environment, and the economy. recently dust storms, originating from arabian countries, have increased remarkably, affecting western and central parts of iran.hysplit model and the mean monthly maps of aai (absorbing aerosol index), surface skin temperature, and top soil layer moisture from omi (ozone measurement instrument) have been u...

Some preliminary results about the verification and validation of SCIAMACHY’s Absorbing Aerosol Index (AAI) are presented. The operational AAI level 2 product of SCIAMACHY is compared to our own AAI algorithm, developed at KNMI. The operational product shows general agreement with the KNMI algorithm but both suffer from large errors in reflectancees, resulting in a large off-set. Also, the negl...

The link between the African Monsoon systems and aerosol loading in Africa is studied using multi-year satellite observations of UV-absorbing aerosols and rain gauge measurements. The main aerosol types occurring over Africa are desert dust and biomass burning aerosols, which are UV-absorbing. The abundance of these aerosols over Africa is characterised in this paper using residues and Absorbin...

We study the quality of the SCIAMACHY Absorbing Aerosol Index (AAI) product developed at our institutes. The AAI in general is determined from the reflectance at two wavelengths in the UV, and is highly sensitive to errors in the absolute radiometric calibration. We apply a degradation correction to the level-1 reflectance and test the temporal behaviour of the resulting AAI data. This we do by...

[1] Multiyear daily surface aerosol aluminum (Al) concentration and sunphotometer measurements at Erdemli (Turkey) sampling station were used to assess the performance of Absorbing Aerosol Index (AAI) and Aerosol Optical Thickness (AOT) retrieved from the daily Total Ozone Mapping Spectrometer (TOMS) over the northeastern Mediterranean. A total of 98 moderate-to-high intensity dust events with ...

The validity of the Absorbing Aerosol Index (AAI) product from the SCanning Imaging Absorption SpectroMeter for Atmospheric CartograpHY (SCIAMACHY) is discussed. The operational SCIAMACHY AAI product suffers from calibration errors in the reflectance as measured by SCIAMACHY and neglect of polarisation effects in the AAI computational algorithm. Therefore, the AAI product was recalculated, comp...

The East Asian dust storms occur in western and northern China, southern Mongolia every year, particularly spring. In this study, we use satellite aerosol products to demonstrate the spatial temporal variation optical depth (AOD) from MODIS, absorbing index (AAI) TOMS OMI, over main storm source regions (MDSR), investigate their relationship vegetation coverage (NDVI), soil properties (surface ...

[1] We investigate rapid around-the-world transport of a smoke aerosol plume released by intense forest fires in southeastern Australia in December 2006. During the first half of December 2006, southeastern Australia suffered from severe drought and exceptionally high temperatures. On 14 December 2006, a passing cold front in combination with the intense heat from the fires causing pyro-convect...
