The August Complex Fire and others this fire season have been sending far-reaching plumes of wildfire smoke into the atmosphere that worsen air quality in California and beyond. Predicting where that smoke will travel and how bad the air will be downwind is a challenge, but Earth-observing satellites can help.

The year 2020 will be remembered for being a very trying year and western wildfires have just added to the year's woes.

Terra on the Earth Observatory: February

Ash Plume and Sea Ice Near Zhupanovsky – Since October, 2015 Zhupanovsky volcano in far eastern Russia has periodically been spewing ash into the atmosphere.  This MODIS image from February 13, 2016 shows an ash plume from Zhupanovsky volcano, which resulted in a code-red for air travel in the region.

Sea surface temperatures indicated that the warm "blob" has dissipated. NASA Earth Observatory image by Jesse Allen, using microwave and infrared multi-sensor SST data from Remote Sensing Systems.

The Demise of the Warm Blob – Ocean surface temperatures, showed a warm “blob” off the northern United State’s coast. This cell of warm ocean water in the Pacific Ocean no longer is present, having lasted from the winter of 2013 through December of 2015.

Waves Above and Below the Water – The Moderate Imaging Spectroradiometer on NASA’s Terra satellite acquired an image of wave patterns in the sky and in the water off the coast of Western Australia.

Snow in the Central U.S. – Snow from a blizzard blanketed parts of the Midwest. This image from Terra’s Moderate Imaging Spectroradiometer (MODIS) captured the snow that remained after the clouds cleared over Nebraska.

Open- and Closed-Celled Clouds over the Pacific – Terra’s Moderate Imaging Spectroradiometer (MODIS) captured in one image examples of two different types of convective clouds, open-celled and closed-celled.

February 5, 2016
Mount Erebus, Antarctica – Mount Erebus in Antarctica, thought to be the most southern volcano is still active. The Advanced Spaceborne Thermal Emissions and Reflection Radiometer (ASTER) on NASA’s Terra satellite captured images in visible and infrared, showing not just the volcano, but also the lava lake in its interior.

Drought in Southern Africa – Normalized Difference Vegetation Index (NDVI) data from Terra’s Moderate Imaging Spectroradiometer (MODIS) sensor are being used to track drought conditions in southern Africa, analyzing the effects of the current strong El Niño on vegetation.
