Russian Smoke Moves Across Alaska

Smoke from the intense fires burning in Russia have moved across Alaska over the past few days:

BAM

This is not unusual. For some past events, Smoke from Asia has moved all the way across to the eastern US.

PyroCb(s) Over Russia

The smoke from the fires in Russia intensified; here's the VIIRS RGB and OMPS AI over VIIRS RGB imagery from yesterday:

BAM

Just after the the S-NPP satellite passed over the area, a PyroCb (or maybe more than one) occurred. Here are images from earlier today.

BAM

Note that I changed the scale from 0-7.5 (indicating dense smoke) on the 19th to 0-10 on the 20th; the largest AI value was actually close to 12. AI values this high indicate a PyroCb event, as they mean that the smoke has been lofted high into the atmosphere.

Smoke from the Soberanes Fire (as Well as Others) in the US

NOAA's National Environmental Satellite, Data, and Information Service (NESDIS) has a Hazard Mapping System Fire and Smoke Product group that works out of their Office of Satellite and Product Operations (yeah, NOAA sure has a lot of departments divisions, and offices):

http://www.ospo.noaa.gov/Products/land/hms.html

This group puts out a daily "Smoke Text Product" describing the conditions over the US. As one would expect, it matches up nicely with the OMPS AI. So here's the VIIRS RGB / OMPS AI over VIIRS RGB image from yesterday:

And, below, here is the text product for yesterday:

DESCRIPTIVE TEXT NARRATIVE FOR SMOKE/DUST OBSERVED IN SATELLITE IMAGERY THROUGH 0300Z September 19, 2016

Smoke: California/Nevada: Moderately dense to thick smoke from the Soberanes Fire in Monterey County of west central California fanned out both to the southwest and offshore and inland to the east and northeast. Farther to the east, the batch of moderately dense to thick smoke from the Owens Fire in Mono County of the Sierra Nevada range exhibited similar behavior with smoke spreading out in multiple directions. A large mass of thinner density smoke from both of these fires stretched from west central Nevada to well off the coast of central and southern California. Farther to the north, a wildfire in southern Modoc County of northeastern California was producing a relatively narrow but moderately dense to locally thick smoke plume which spread to the east across northern Nevada.

Arizona/New Mexico: A sizable area of thin density smoke attributed to fires in both northern and central Arizona as well as a couple of fires in northwestern and north central New Mexico, was visible over much of northern and central Arizona and northwestern and north central New Mexico. Moderately dense to locally thick smoke was analyzed closer to the cluster of fires in central Arizona.

Utah/Colorado: A number of fires and visible smoke plumes were seen scattered across Utah as well as western and southwestern Colorado with the most significant plume emanating from a fire in eastern Beaver County of south central Utah. This moderately dense to thick plume moved to the east and northeast during the afternoon.

THIS TEXT PRODUCT IS PRIMARILY INTENDED TO DESCRIBE SIGNIFICANT AREAS OF SMOKE ASSOCIATED WITH ACTIVE FIRES AND SMOKE WHICH HAS BECOME DETACHED FROM THE FIRES AND DRIFTED SOME DISTANCE AWAY FROM THE SOURCE FIRE. TYPICALLY OVER THE COURSE OF ONE OR MORE DAYS. AREAS OF BLOWING DUST ARE ALSO DESCRIBED. USERS ARE ENCOURAGED TO VIEW A GRAPHIC DEPICTION OF THESE AND OTHER PLUMES WHICH ARE LESS EXTENSIVE AND STILL ATTACHED TO THE SOURCE FIRE IN VARIOUS GRAPHIC FORMATS ON OUR WEB SITE:

Russian Fires Flare Up

Fires in Russia (just to the northwest of Lake Baikal) have flared up again. Both VIIRS and OMPS are seeing dense smoke:
