Washington, D.C. – Earth’s global average surface temperature in 2020 tied with 2016 as the warmest year on record, according to an analysis by NASA.
Continuing the planet’s long-term warming trend, the year’s globally averaged temperature was 1.84 degrees Fahrenheit (1.02 degrees Celsius) warmer than the baseline 1951-1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. 2020 edged out 2016 by a very small amount, within the margin of error of the analysis, making the years effectively tied for the warmest year on record.
NASA’s Atmospheric Infrared Sounder instrument observes California Wildfires’ Carbon Monoxide output
Pasadena, CA – NASA’s Atmospheric Infrared Sounder (AIRS), aboard the Aqua satellite, captured carbon monoxide plumes coming from California wildfires last week. There were 28 major wildfires burning across the state as of September 14th, 2020. This includes the August Complex Fire, which started on August 17th and has since burned over 471,000 acres, making it the largest fire on record in California.
The animation shows three-day averages of carbon monoxide concentrations around 3 miles (5 kilometers) up in the atmosphere between September 6th and September 14th.
NASA’s Atmospheric Infrared Sounder (AIRS) instrument observes Hurricane Douglas, Tropical Storm Hanna
Pasadena, CA – NASA’s Atmospheric Infrared Sounder (AIRS) was monitoring two storm systems as they took aim at portions of Hawaii and Texas on July 26th. Perched on NASA’s Aqua satellite, AIRS is an instrument that studies Earth’s weather and climate.
As of 11:00am local time, Hurricane Douglas was sweeping toward Hawaii with the potential to directly hit portions of the islands, from Maui to Kauai, in the late afternoon or evening.
Pasadena, CA – Tropical Storm Fay is sweeping across New England, with the center of the storm making landfall about 10 miles (15 kilometers) north-northeast of Atlantic City, New Jersey, at around 5:00pm local time.
At that time, Fay had maximum sustained winds of around 50 mph (85 kph). Forecasters predicted the storm will dump up to 7 inches (18 centimeters) of rain along its path from Delaware into New Jersey.
Pasadena, CA – A new NASA study shows that over the last 20 years, the atmosphere above the Amazon rainforest has been drying out, increasing the demand for water and leaving ecosystems vulnerable to fires and drought. It also shows that this increase in dryness is primarily the result of human activities.
Scientists at NASA’s Jet Propulsion Laboratory in Pasadena, California, analyzed decades of ground and satellite data over the Amazon rainforest to track both how much moisture was in the atmosphere and how much moisture was needed to maintain the rainforest system.
Pasadena, CA – NASA’s Jet Propulsion Laboratory has several instruments and spacecraft with eyes on Hurricane Dorian, capturing different types of data from the storm.
NASA’s Atmospheric Infrared Sounder (AIRS), aboard the Aqua satellite, senses emitted infrared and microwave radiation from Earth. The information is used to map such atmospheric phenomena as temperature, humidity, and cloud amounts and heights.
Pasadena, CA – NASA’s Atmospheric Infrared Sounder (AIRS) instrument, aboard the Aqua satellite, has produced new data that shows the movement high in the atmosphere of carbon monoxide associated with fires in the Amazon region of Brazil.
This time series maps carbon monoxide at an altitude of 18,000 feet (5,500 meters) from August 8th-22nd, 2019. As the series progresses, the carbon monoxide plume grows in the northwest Amazon region then drifts in a more concentrated plume toward the southeastern part of the country.
Pasadena, CA – On Friday, July 12th, 2019, at around 2:00pm local time, NASA’s Atmospheric Infrared Sounder (AIRS), aboard the Aqua satellite, captured imagery of Tropical Storm Barry in the Gulf of Mexico. According to the National Hurricane Center, Barry is expected to make landfall over the Louisiana coast on Saturday, likely as a hurricane.
In the infrared AIRS image, the large purple area indicates very cold clouds that have been carried high into the atmosphere by deep thunderstorms. These clouds are associated with heavy rainfall. Warmer areas with shallower rain clouds are shown in blue and green. And the orange and red areas represent mostly cloud-free air.

Pasadena, CA – A new NASA study shows that warming of the tropical oceans due to climate change could lead to a substantial increase in the frequency of extreme rain storms by the end of the century.
The study team, led by Hartmut Aumann of NASA’s Jet Propulsion Laboratory in Pasadena, California, combed through 15 years of data acquired by NASA’s Atmospheric Infrared Sounder (AIRS) instrument over the tropical oceans to determine the relationship between the average sea surface temperature and the onset of severe storms.

Pasadena, CA – Hurricane Michael plowed into the Florida panhandle Wednesday, October 10th, 2018 as a major Category 4 storm — the strongest hurricane ever to hit that region. Many NASA instruments are keeping tabs on Michael from space, including the Atmospheric Infrared Sounder (AIRS) and the Multi-angle Imaging SpectroRadiometer (MISR).
The first image, taken by AIRS, shows Hurricane Michael just off the west coast of Florida on October 10th in the early morning hours local time. The large purple area indicates very cold clouds at about -90°F (-68°C) carried high into the atmosphere by deep thunderstorms.
