The advanced Ozone Mapping and Profiler Suite (OMPS) tracks the health of the ozone layer and measures the concentration of ozone in the Earth's atmosphere. OMPS consists of three spectrometers: a downward-looking nadir mapper, nadir profiler and limb profiler. The entire OMPS suite, OMPS-Nadir (OMPS-N) and OMPS-Limb (OMPS-L), currently fly on board the Suomi NPP spacecraft.

The August Complex fire formed under very hot and dry conditions in northern California on August 17th, 2020. Reportedly, 37 individual fires initiated by lightning strikes merged to create this conflagration, which claimed the life of one firefighter on August 31st, 2020 according to the U.S. Forest Service. Researchers from the MISR Active Aerosol Plume-Height (AAP) Project, based out of NASA Goddard Space Flight Center and the University of Maryland, along with colleagues from JPL and the NASA Langley Research Center used data from multiple Earth observing satellites to map the properties...

Damage Proxy Map of the LNU Lightning Complex fires showing likely damaged areas in red and yellow.
As record-setting fires continue to ravage the western United States, with large fire complexes currently burning in California, Oregon, Washington State, and Colorado, coordinators and scientists from the NASA Earth Applied Sciences Disasters Program are hard at work developing maps, imagery and analysis to aid local agencies and response teams in understanding the impacts from the fires and the potential risks to people, infrastructure, and the environment. In late August the...

OMPS shows smoke plumes from the California fires
Climate and fire scientists have long anticipated that fires in the U.S. West would grow larger, more intense, and more dangerous. But even the most experienced among them have been at a loss for words in describing the scope and intensity of the fires burning in West Coast states in September 2020. Lightning initially triggered many of the fires, but it was ...

OMPS S02 Measurements from Raikoke
On June 22, 2019, the Raikoke volcano on Kuril Island erupted, spewing large volumes of ash and volcanic gases into the atmosphere. Volcanic ash (VA) and gasses pose a major threat to aviation, while gasses including sulfur dioxide (SO2) also impact climate and stratospheric ozone. Large concentrations of SO2 in the volcanic plumes pose a short-term hazard to aviation by impacting cabin air quality and also have possible long-term effects on aircraft. Traditionally, SO2 serves as a proxy for ash, which is the primary hazard to aircraft engines, frame and avionics. This map of the northern...

Researchers from the NASA Earth Applied Sciences Disasters Program are using data from multiple satellites to study the formation of fire-induced clouds from the Australian bushfires, known as pyrocumulus clouds, and their potential impacts to Earth’s atmosphere and climate.  Data from the NASA-NOAA OMPS (above) and ESA TROPOMI instruments (below) show aerosols and carbon monoxide from the Australia fires spreading across the Tasman Sea.

NASA scientists using data from its NOAA/NASA Suomi NPP satellite, has traced the movement of the smoke coming off the Australian fires across the globe showing that it has circumnavigated the Earth. In an image created from data gathered by the Ozone Mapping and Profiler Suite (OMPS) Nadir Mapper on Suomi NPP, a black circle shows the smoke which had been traced from its origins coming back to the eastern region of Australia after having traveled around the world. Suomi NPP carries carry five science instruments and is the first satellite mission to address the challenge of acquiring a wide...

Satellite data from the OMPS-NM instrument is used to create an ultraviolet aerosol index to track the aerosols and smoke. Credits: NASA/Colin Seftor A fleet of NASA satellites working together has been analyzing the aerosols and smoke from the massive fires burning in Australia. The fires in Australia are not just causing devastation locally. The unprecedented conditions that include searing heat combined with historic dryness, have led to the formation of an unusually large number...

SNPP/OMPS SO2 map for Sierra Negra
SNPP/OMPS SO2 map for Sierra Negra on June 27, 2018. Based on the coincident IR observations the plume altitude increases moving away from the volcano. AIRS is not detecting any SO2 between the volcano and ~100ºW. If one assumes all the SO2 between the volcano and 100ºW is lower tropospheric and the rest is in the upper troposphere, the total SO2 mass is ~280 kilotons (~0.3 Tg) with ~0.1 Tg in the UTLS.

VIIRS image of the Fuego eruption from June 3, 2018
Fuego in Guatemala is one of Central America’s most active volcanoes. For years, the towering Volcán de Fuego has puffed continuously, punctuated by occasional episodes of explosive activity, big ash plumes, lava flows, and avalanche-like debris slides known as pyroclastic flows. Just before noon on June 3, 2018, the volcano produced an explosive eruption that sent ash billowing thousands of meters into the air. A deadly mixture of ash, rock fragments, and hot gases...

OMPS SO2 map for the Kilauea eruption from May 22nd, 2018.
May 22nd 2018: OMPS SO2 map for the Kilauea eruption from May 22nd, 2018. The Ozone Mapping Profiling Suite (OMPS) Hyperspectral UV instrument onboard the Suomi NPP (SNPP) satellite observed large extent of the volcanic SO2 clouds emitted from Kilauea eruptions  on May 21-22 on Hawai'i Big island. The estimated SO2 emission rate is still elevated, at ~10-30,000 tons/day (2-6 times the long-term average flux for Kilauea) The SNPP orbit was not...
