Satellite and Modelled Aerosol

Here we present a qualitative comparison of MODIS NRT data (total AOD) and model output (AODEM -  Mineral Dust Optical Depth and CHIMERE - Crustal fraction of PM10 at ground level) generated in the framework of the I-AMICA Project.

Please note that due to issues with the provision of MODIS NRT data, some maps can be not updated.

  • MODIS NRT data-products are taken by The local equatorial crossing time is approximately 10:30 a.m. for Terra and approximately 1:30 p.m. for Aqua satellite;
  • MODIS/Terra Near Real Time (NRT) Aerosol 5-Min L2 Swath 10km (Collection 005) and MODIS/Aqua Near Real Time (NRT) Aerosol 5-Min L2 Swath 10km (Collection 005) are remapped over EUR54 domain day by day;
  • WRF run is performed by using operational NOMADS files;
  • CHIMERE run is carried out over European domain (EUR54, the mather domain of other two nested domains, ITA18 and IAM6). The inventory emission is taken by EMEP dataset (i.e., the meteorology by WRF (as reported at previous point)
  • AODEM run is performed by using CHIMERE outputs;
  • AODEM and CHIMERE output are plotted only for pixels over which MODIS data were available
