Central Africa is still on fire a month after the October 30 image of the fire was posted. Most likely these fires are agricultural in nature.

Just like the Woolsey Fire's scar which was highlighted on the NASA Fire page on November 16, the Camp Fire scar is visible from space in this image taken by the Terra satellite on November 26, 2018.

In the wake of a fire, a burn scar appears which takes a long time to heal. This scar is from the Woolsey fire which has taken its toll around Thousand Oaks, California.

MOPITT Helping Shape the Future of Air Quality Monitoring

Measurements of Pollution in the Troposphere (MOPITT) on NASA’s Terra satellite is being used to prove a concept in which new geostationary satellites could improve how agencies monitor and forecast air quality. Chemistry-climate model output would be combined from satellite data from a fleet of geostationary satellites.

“We think the new perspective made possible by geostationary sensors would provide data that is useful for everyday air quality forecasting, as well as for early warnings about extreme events, like the effects of wildfires,” said Helen Worden, NCAR scientist and member of the research team, according to the UCAR website.

MOPITT provides one to two measurements over a given location per day. The geostationary fleet would allow multiple measurements of certain locations per day, making it possible to track emissions over rush hour versus lower traffic times in some urban areas.

The statistical technique used to test the geostationary fleet as a proof of concept was first developed to analyze data from MOPITT, which pioneered the measurement of carbon monoxide from space.
