The Ozone Mapping and Profiler Suite (OMPS) and the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-NASA Suomi NPP satellite captured this extremely think blanket of smoke along the West Coast on 9 September 2020. OMPS measured smoke clouds over the western U.S. with higher aerosol index values than anything Colin Seftor, an atmospheric scientist at NASA’s Goddard Space Flight Center, says he has ever seen with the instrument.

California’s wildfire smoke plumes are unlike anything previously seen – California fire carbon emissions in 2020 exceed previous record by nearly 2 times

By Matthew Cappucci 12 September 2020 (The Washington Post) – More than 3.1 million acres have burned in California this year, part of a record fire season that still has four months to go. A suffocating cloud of smoke has veiled the West Coast for days, extending more than a thousand miles above the Pacific. And the […]

Air temperatures across the United States on 6 September 2020, when much of the Southwest roasted in a dramatic heatwave. The map was derived from the Goddard Earth Observing System (GEOS) model and represents temperatures at 2 meters (about 6.5 feet) above the ground. The darkest red areas are where the model shows temperatures surpassing 113°F (45°C). Graphic: Joshua Stevens / NASA Earth Observatory

California heatwaves are becoming more frequent and lasting longer – “This has serious consequences for the fire season in Southern California”

By Kasha Patel 11 September 2020 (NASA) – In early September 2020, an intense heatwave broke temperature records in several locations in Southern California. The dry, hot conditions helped fuel new and existing fires, which have consumed tens of thousands of acres of land. According to recently published research, these extremes fit a long-term trend toward longer and more […]

On 9 September 2020, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite captured this natural-color image of thick smoke streaming from a line of intense fires in Oregon and California. Many communities in the region are facing extremely poor and sometimes hazardous air quality. Data: NASA EOSDIS/LANCE and GIBS/Worldview. Photo: Lauren Dauphin / NASA

Autumn could deliver the worst of California’s 2020 fire season – A scorching Labor Day weekend brought an all-time record heat and unprecedented fire spread, but fire risks climb in the fall

By Bob Henson 8 September 2020 (Yale Climate Connections) – Temperatures reached ghastly levels in southern California and wildfire carved a path close to two of the state’s iconic national parks as a historic heat dome gripped the western United States during the traditional end-of-summer Labor Day weekend. The heat had eased somewhat by Tuesday, […]

February 2020 second warmest on record globally

By Bob Henson 13 March 2020 (Weather Underground) – Research groups across the world concur that this past northern winter (December-February) was the second-warmest on record globally, in records going back more than a century. The latest group to confirm this finding is NOAA, in its monthly State of the Climate report issued Friday. The winter result […]

These maps show nitrogen dioxide (NO2) values across China from 1 January 2020 to 20 January 2020 (before the quarantine) and 10 February 2020 to 25 February 2020 (during the quarantine). The data were collected by the Tropospheric Monitoring Instrument (TROPOMI) on ESA’s Sentinel-5 satellite. A related sensor, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite, has been making similar measurements. Graphic: Joshua Stevens / NASA Earth Observatory

Airborne nitrogen dioxide plummets over China as quarantine shuts down industry

By Kasha Patel 28 February 2020 (NASA) – NASA and European Space Agency (ESA) pollution monitoring satellites have detected significant decreases in nitrogen dioxide (NO2) over China. There is evidence that the change is at least partly related to the economic slowdown following the outbreak of coronavirus. At the end of 2019, medical professionals in […]

Image of the Day: Antarctica melts under its hottest days on record

By Kasha Patel 21 February 2020 (NASA) – On 6 February 2020, weather stations recorded the hottest temperature on record for Antarctica. Thermometers at the Esperanza Base on the northern tip of the Antarctic Peninsula reached 18.3°C (64.9°F)—around the same temperature as Los Angeles that day. The warm spell caused widespread melting on nearby glaciers. The warm […]

Satellite view of tropospheric NO2 VCDs over the Permian basin for August 2018, seen from the Ozone Monitoring Instrument (OMI) and Tropospheric Monitoring Instrument (TROPOMI) aboard NASA and ESA satellites. OMI has a ground pixel size of 13 x 24 km2 and was gridded onto a 0.07 by 0.07 degrees latitude/longitude grid. TROPOMI has a footprint of 3.5 x 7 km2 and was averaged onto a 0.02 by 0.02 degrees latitude/longitude grid. The increased spatial resolution of the TROPOMI measurements is clearly visible. The red outline denotes the area used for the multivariate regression fits. Graphic: Dix, et al., 2020 / Geophysical Research Letters

Air pollution from oil and gas production sites visible from space – U.S. and European satellites help scientists measure nitrogen dioxide from drilling, production, and flaring

15 January 2020 (CIRES) – Oil and gas production has doubled in some parts of the United States in the last two years, and scientists can use satellites to see impacts of that trend: a significant increase in the release of the lung-irritating air pollutant nitrogen dioxide, for example, and a more-than-doubling of the amount […]

Earth had its hottest decade on record in 2010s – “2020 is off to a horrifying climate start, and I fear what the rest of the year will bring to our doorsteps”

By Seth Borenstein 15 January 2020 WASHINGTON (AP) – The decade that just ended was by far the hottest ever measured on Earth, capped off by the second-warmest year on record, two U.S. agencies reported Wednesday. And scientists said they see no end to the way man-made climate change keeps shattering records. “If you think […]

Australia fire smoke will complete a full circuit of Earth, NASA says

14 January 2020 (BBC News) – Smoke from the massive bushfires in Australia will soon circle the Earth back to the nation, says NASA. Massive infernos have raged along the nation’s east coast for months, pushing smoke across the Pacific. NASA said plumes from blazes around New Year’s Day had crossed South America, turning skies […]

As many fires are still burning in Australia, a regular GLOBE Observer (Glenn Evans in Coogee, New South Wales, about 10 km/6 miles southeast of Sydney), has been taking consistent clouds observations from the same location over the last few weeks, sometimes multiple observations on the same day. In this short video, you can see a compilation of their ground observations in December 2019, facing west and south alongside satellite imagery from the same day taken by the MODIS instrument on the Aqua satellite. Notice the sky coloration when heavy smoke plumes are visible in the satellite image, as well as the days when there is both haze and other types of clouds in the sky. Video: NASA GLOBE Observer

A megafire measuring 1.5 million acres forms in Australia as bushfires merge – “It is too late to leave”

By Andrew Freedman 10 January 2020 (The Washington Post) – Australia’s bushfire crisis worsened Thursday night into Friday as hot, dry and windy conditions redeveloped across the country’s hard-hit southeast, causing two large blazes to merge into one. The new “megafire” measures about 1.5 million acres, about the size of the state of Delaware or […]
