Pasadena, CA – Although there are telltale signs that a volcano is likely to erupt in the near future – an uptick in seismic activity, changes in gas emissions, and sudden ground deformation, for example – accurately predicting such eruptions is notoriously hard.
This is, in part, because no two volcanoes behave in exactly the same way and because few of the world’s 1,500 or so active volcanoes have monitoring systems in place. Under the best of circumstances, scientists can accurately forecast an eruption of a monitored volcano several days before it happens. But what if we knew months or even years in advance?
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.
Pasadena, CA – As California experiences one of the worst wildfire seasons on record, NASA is leveraging its resources to help. Scientists supporting the agency’s Applied Sciences Disaster Program in the Earth Sciences Division are generating maps and other data products that track active fires and their smoke plumes while also identifying areas that may be susceptible to future risks.
“When disasters like this occur, we are able to swiftly respond to requests from our partners who need images and mapping data,” said David Green, manager of the Disasters Program at NASA Headquarters in Washington.
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.
Greenbelt, MD – NASA’s Aqua satellite provided a visible image of Hurricane Douglas is it continued on its track toward Hawaii. The storm is now a Category 2 hurricane and warnings were posted on July 25th, 2020 as the storm approaches.
The Central Pacific Hurricane Center has posted warnings for Douglas.
A Tropical Storm Warning is in effect for Hawaii County, Maui County, including the islands of Maui, Lanai, Molokai and Kahoolawe.
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.
Greenbelt, MD – NASA’s Aqua satellite gathered infrared imagery and cloud top temperature data on Tropical Depression Cristobal, and it revealed the heavy rainmaking capability of the storm.
The National Hurricane Center (NHC) forecasts Cristobal to track northward through the Gulf of Mexico and toward Louisiana’s coast. Watches and warnings have gone into effect.
On June 5th, the NHC issued a Storm Surge Watch for the northern Gulf of Mexico coast from Indian Pass to Arepika, Florida, and from Grand Isle, Louisiana, to Ocean Springs, Mississippi, including Lake Borgne. In addition, a Tropical Storm Watch has been issued for the northern Gulf of Mexico coast from Intracoastal City Louisiana to the Alabama/Florida border, including Lake Pontchartrain and Lake Maurepas.
Mountain View, CA – The research project looked specifically at how long the growing season lasts in Yellowstone National Park, from snowmelt in spring to first snowfall in autumn, and the vegetation that covers the land in between.
The satellite data revealed that the season for vegetation growth has been getting longer, likely a result of climate change decreasing the severity of winters and warming average temperatures overall.
Studying national parks is helpful for this type of climate research, because human land use is restricted in these spaces.
Greenbelt, MD – As Hurricane Dorian continued to lash the coast of the Carolinas NASA’s IMERG assessed the rainfall the storm generated and NASA’s Aqua satellite provided a look at the temperatures of the cloud tops to assess strength.
By Friday morning, September 6th, Hurricane Dorian was located off the coast of North Carolina, having generated tornadoes the previous day as the northern rainband came ashore in North Carolina. NASA’s satellite-based real time precipitation estimates suggest that, during the past day, most of the areas experiencing over 10 inches of rain accumulation remained offshore, while Dorian did drop heavy rain on South Carolina and North Carolina.
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.
