The Windy Fire is also affecting several communities where many structures and infrastructure are threatened. Use the back and forward arrows in the lower left corner of the embedded map to see when the fires began to be visible in the satellite imagery.
The KNP Complex and Windy Fires are in the lower right with smoke from these fires covering the Central Valley. The KNP Complex Fire is impacting the Sequoia and Kings Canyon National Parks as well as residences and infrastructure in the region.

Overlaid on the image are the Aqua/MODIS Fires and Thermal Anomalies layer which is shown as orange dots, these represent the center of a 1km pixel containing one or more fires. These images are called true-color or natural color because this combination of wavelengths is similar to what the human eye would see. This image is a true-color Red-Green-Blue (RGB) composite where Red is Band 1, Green is Band 4, and Blue is Band 3. This image was acquired by Moderate Resolution Imaging Spectroradometer ( MODIS), aboard the Aqua satellite. If we look at the Pacific timezone where the band calls home, another 4% of those last summer evenings come on September 21st, but that's still not where the date in the song comes from.True-color corrected reflectance image of the KNP Complex and Windy Fires in California. You have to go back to the late 15th century to find a September equinox on the 21st. 24 in 19, because leap year was skipped in 1900 (every 4 years except years evenly divisible by 100, but not 400, complexity necessary to better align to that 365.24219 tropical year). 2 - HD satellite images produced twice daily from Suomi-NPP, and MODIS Aqua and Terra.
Looking back in the eastern timezone since the switch to the Gregorian calendar in October 1582, the September equinox happens on Sept. Two functions that zoom.earth uses that I'd like to see Windy also add are: 1 - True colour global satellite imagery from the same sources that zoom.earth uses (NOAA GOES, JMA Himawari-8 & EUMETSAT Meteosat) that are updated every 10mins. This moment in time happens about 6 hours later each year, except on leap years when that forward progress is erased and the equinox occurs 18 hours earlier. The variation comes from misalignment between the length of the calendar year and tropical year, or the time it takes for the Earth to complete a trip around the Sun.Īutumn begins tomorrow with the September equinox when the Sun is directly over the equator at 3:20 p.m.
The first astronomical day of Autumn falls (pun intended) nearly equality between Sept.
