July 24-28, 2020 – Smoke From Siberia Reaches Alaska
Most of Alaska is now covered by smoke from the #SiberianFires as it wraps around a low-pressure system. The #SNPP #VIIRS RGB+hotspot image from earlier today is on the left with the #OMPS aerosol index overlaid on the right. Most of the smoke lies over the system’s clouds.
The #SiberianFires produced a couple of pyroCbs yesterday, and some of the heavy smoke has now moved across to western Alaska. The situation earlier today as seen by #SNPP #VIIRS RGB+hotspot on the left, and with the #OMPS aerosol index overlaid on the right.
The #SiberianFires continue to pump out heavy smoke that covers a huge area and that is now moving out into the Pacific towards Alaska. The #SNPP #OMPS aerosol index overlaid on the #VIIRS RGB+hotspot imagery for the 24th-26th July.
