OMI/OMPS

Overview

Ozone Monitoring Instrument (OMI) is a contribution of the Netherlands's Agency for Aerospace Programs (NIVR) in collaboration with the Finnish Meteorological Institute (FMI) to the EOS Aura mission. It will continue the TOMS record for total ozone and other atmospheric parameters related to ozone chemistry and climate. OMI measurements will be highly synergistic with the other instruments on the EOS Aura platform.

OMPS is the new operational version of the OMI sensor on SUOMI NPP and JPSS.

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...

Data from the the Ozone Mapping Profiler Suite (OMPS) sensor on the Suomi NPP satellite, acquired April 30 - May 5, 2018
Data from the the Ozone Mapping Profiler Suite (OMPS) sensor on the Suomi NPP satellite, acquired April 30 - May 5, 2018 Kilauea has been erupting continuously since 1983, but in late April and early May 2018 the volcanic eruption took a dangerous new turn. During the last week of April, the lava lake at Halema‘uma‘u Overlook crater ...

Mt. Fuego eruption
  It is one of Central America’s most active volcanos. Volcán de Fuego puffs continuously without notice by nearby communities, punctuated by episodes with explosive activity, huge ash plumes, and lava flows. The Guatemalan volcano is at it again, beginning its latest bout of unruly behavior on January 31, 2018. On the next day, the Operational Land Imager (OLI) on Landsat 8...

SO2 emission map
Acquried November 29, 2017 Figure 1 shows volcanic sulfur dioxide (VSO2) plume emitted from the eruption of Mt. Agung (Bali, Indonesia) and first captured by Aura/OMI and SNPP/OMPS UV spectrometers afternoon overpasses on November 26 2017, just hours after the beginning of the explosive magmatic phase of the eruption. The data show total SO2 column amounts in Dobson Units (1 DU = 2.69 1016 molecules SO2 per cm2). Background SO2 concentrations in this location are undetectable from space,...
