And so the story continues. Word from Washington today was that lightning storms were expected to raise new fires in the drought savaged northwest states. The MODIS AQUA red-green-blue (RGB) imagery shows that fires are still raging in Oregon, Washington and Idaho. The smoke over Idaho was so intense that the Aerosol Optical Depth retrievals were missing in the middle of the plume (identified as cloud). EPA's AIRNOW website has identified large areas as Unhealthy.
The smoke spread all the way south to Texas and Louisiana (AOD image left). The HMS system has identified large areas of the country as smoke covered (lower, right).
AIRNOWTech has gone over to Version 2 and I'm still learning how to use it. On the left is the overlay of fires in red, HMS smoke in grey, EPA sites as triangles or colored dots where there is data, wind barbs.... A bit of a graphic salad though so it will take some time to get this right. On the right image, smoke from the fires in Oregon, Washington and Idaho as wrapped up in the Vancouver basin and now will impact the highly populated areas of Seattle and Vancouver.
