Daily Snapshots of Suomi NPP True Color Imagery overlain with Fire Detection points (in red), from 25 August – 5 September 2017 (Click to animate)<\/p><\/div>\n

GOES-16 data posted on this page are preliminary, non-operational and are undergoing testing<\/strong><\/p>\n

Dry weather over the Pacific Northwest (and over Idaho and Montana) has created an ideal environment lately for wildfires, and much of the region is shrouded in smoke from those fires as shown in the Suomi NPP True Color Imagery, above, from this site<\/a>. \u00a0Note the red points that are Suomi-NPP-detected fires; they persist from day to day, and some grow in size during the course of the animation. GOES-16 Animations of True Color (in this case, the CIMSS Natural True Color product that is created using Bands 1, 2 and 3 (0.47 \u00b5m, 0.64 \u00b5m and 0.86 \u00b5m, respectively)), below, (also available here<\/a>; a similar product from CIRA is available here<\/a>), show the pall of smoke as well. Air Quality Alerts from the National Weather Service were widespread on 6 September<\/a>.<\/p>\n

GOES-16 has multiple channels and products that can view both the Smoke and the Fires that produce the smoke. In addition to the visible imagery, Fire Products, below, can characterize the Temperature, Power (in megawatts) and area (in square meters) of the fire detected by GOES-16.\u00a0 On this day, clouds over the fires in Oregon mean that satellite detection is challenged, even though the by-product, smoke, is apparent.\u00a0 Fires over Idaho are readily apparent however.\u00a0 These fires were also detected by the 3.9 \u00b5m Shortwave Infrared channel<\/a> on GOES-16, the traditional fire-detection channel (used in concert with 10.3 \u00b5m, the clean window channel).\u00a0 Imagery at 1.6 \u00b5m and 2.2 \u00b5m imagery can also be used to highlight hot fires;\u00a0 that will be the subject of a future blog post.<\/p>\n

The mp4 animation, below, shows CIMSS Natural True Color over the Full Disk on 5 September 2017.\u00a0 The Full Disk View allows a better visualization of how the smoke is moving (and underscores how widespread it is) — and it shows Hurricane Irma as well.<\/p>\n
