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.

Drought Stressing California’s Plantscape

Persistent dry weather has grown more worrisome in the American West, with nearly two thirds of the region experiencing some level of drought. By most measures, the state of California is suffering through the worst of it. The effects of the dry spell are visible in the mountains, where snow pack is lacking, and now in the vegetation cover on the landscape. Nearly all of California was in a state of extreme drought at the end of January 2014. The past three months (November to January), six months (since August) and twelve months were all the driest periods in California since record-keeping started in 1885. From February 1, 2013, through January 31, 2014, a statewide average of 6.97 inches (177.04 millimeters) of rain fell; the norm is 22.51 inches (571.75 millimeters). The map above shows the impact of drought on California’s farms, forests, and wild lands. Based on data from the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites, the map contrasts plant health from January 17 to February 1, 2014, against average conditions for the same period over the past decade.
