NASA measures Dorian’s heavy rainfall from Bahamas to Carolinas

Hurricane Dorian continues to generate tremendous amounts of rainfall, and has left over three feet of rain in some areas of the Bahamas and is now lashing the Carolinas. NASA’s IMERG product provided a look at those rainfall totals. By…

NASA-NOAA satellite finds wind shear pushing on Tropical Storm Gabrielle

NASA-NOAA’s Suomi NPP satellite passed over the eastern Atlantic Ocean and infrared data revealed that the storm was being adversely affected by wind shear, pushing its strongest storms northeast of its center. NASA-NOAA’s Suomi NPP satellite used infrared light to…

Satellite finds a ‘hook’ of heavy rainfall in Hurricane Juliette

From its vantage point in orbit around the Earth, when the Global Precipitation Measurement mission or GPM core satellite passed over the Eastern Pacific Ocean, it gathered data on rainfall rates occurring in Hurricane Juliette. The areas of strongest rainfall…

Source water key to bacterial water safety in remote Northern Australia

In the wet-dry topics of Australia, drinking water in remote communities is often sourced from groundwater bores. The geochemistry of that groundwater impacts the occurrence of opportunistic pathogens in the drinking water supply, researchers now report in PLOS Neglected Tropical…

Kīlauea lava fuels phytoplankton bloom off Hawai’i Island

When Kīlauea Volcano erupted in 2018, it injected millions of cubic feet of molten lava into the nutrient-poor waters off the Big Island of Hawai’i. The lava-impacted seawater contained high concentrations of nutrients that stimulated phytoplankton growth, resulting in an…

Tropical storm Faxai gets a name and NASA gets an infrared picture

Tropical Storm 14W has been moving through the Northwestern Pacific Ocean for several days and has now been renamed Faxai. NASA’s Aqua satellite passed over the newly renamed storm and took the temperature of Faxai’s clouds and storms. NASA’s Terra…

New study tracks sulfur-based metabolism in the open ocean

One of the planet’s most active ecosystems is one most people rarely encounter and scientists are only starting to explore. The open ocean contains tiny organisms — phytoplankton — that perform half the photosynthesis on Earth, helping generate oxygen for…

GPM finds a band of heavy rainfall in Tropical Storm Gabrielle

The Global Precipitation Measurement mission or GPM core satellite provided information about the rate in which rain was falling within the Eastern Atlantic Ocean’s latest tropical storm, Gabrielle. Tropical Depression 8 formed around 5 p.m. EDT on Tuesday, Sept. 3.…

NASA analyzed Tropical Storm Fernand’s strength before landfall

NASA’s Aqua satellite provided forecasters at the National Hurricane Center with infrared data and cloud top temperature information for Tropical Storm Fernand as it was making landfall in northeastern Mexico. Those temperatures indicated Fernand’s rainmaking capabilities. The infrared data also…

NASA catches Hurricane Juliette over Mexico’s Socorro Island

Although Hurricane Juliette is no longer a major hurricane in the Eastern Pacific Ocean, NASA’s Aqua satellite revealed there are still powerful thunderstorms around its center and captured an image of the storm over Socorro Island, Mexico. Aqua provided forecasters…

NASA estimates Hurricane Dorian’s massive Bahama rainfall totals

Hurricane Dorian dropped excessive rainfall on the Bahamas and NASA calculated the rainfall the storm generated. “By Wednesday morning, September 4, the rain accumulation from Hurricane Dorian exceeded 36 inches in an area that included parts of Grand Bahama Island…

Solutions to urban heat differ between tropical and drier climes

In summer heat, cities may swelter more than nearby suburbs and rural areas. And while the size of this urban heat island effect varies widely among the world’s cities, heat island intensity can largely be explained by a city’s population…

GPM analyzes tropical depression Kajiki’s rainfall over Vietnam and Laos

The Global Precipitation Measurement mission or GPM core satellite provided a look at rainfall rates in Tropical Depression Kajiki after it made a quick landfall in Vietnam. On Sept. 2, Kajiki formed as Tropical Depression 16W in the South China…

Major Hurricane Juliette’s emerging eye spotted in NASA satellite imagery

NASA’s Aqua satellite passed over the Eastern Pacific Ocean and provided an image of Hurricane Juliette as its eye began to emerge. Juliette has grown into a major hurricane, about 450 miles southwest of the southern tip of Baja California,…

NASA finds tropical storm 14W strengthening

Tropical Storm 14W formed as a depression a couple of days ago in the Northwestern Pacific Ocean and strengthened into a tropical storm on Sept. 2. Infrared data from NASA’s Aqua satellite shows some powerful thunderstorms fueling further intensification. On…

NASA infrared eye analyzes typhoon Lingling

The storm that became Typhoon Lingling strengthened very quickly in the Northwestern Pacific Ocean and infrared imagery from NASA revealed the powerful thunderstorms fueling that intensification. Lingling formed on Sept. 2 as Tropical Depression 15W and strengthened quickly into a…

Revolutionizing water quality monitoring for our rivers and reef

New, lower-cost help may soon be on the way to help manage one of the biggest threats facing the Great Barrier Reef. That threat is pollution from land making its way downstream by way of the many rivers and streams…

NASA infrared data reveals rainmaking potential in tropical depression 7

Another Atlantic Ocean basin depression formed while Hurricane Dorian is still wreaking havoc on the Bahamas and affecting the southeastern U.S. Infrared imagery from NASA’s Aqua satellite shows that Tropical Depression 7 in the western Gulf of Mexico has developed…

NASA’s IMERG estimates hurricane Dorian’s rain

In the early hours of Tuesday, September 3, Hurricane Dorian had been stationary over the island of Grand Bahama for 18 hours, most of the time as a category 5 hurricane. Storm-total rain accumulation over parts of Grand Bahama and…

Snowfall frequency declining across Northwest, PSU study finds

With warming temperatures, average snowfall frequency is estimated to decline across the Pacific Northwest by 2100 — and at a faster rate if greenhouse emissions are not reduced, according to a new Portland State University study. Researchers in PSU’s Climate…

NASA satellites on-hand as Dorian becomes a category 3 hurricane

As Hurricane Dorian was upgraded to a Category 3 hurricane on the Saffir-Simpson Hurricane Wind Scale, NASA’s fleet of satellites were gathering data during the day to assist weather forecasters and scientists. At 2:00 pm EDT the National Hurricane Center…

Deep snow cover in the Arctic region intensifies heat waves in Eurasia

Persistent abnormally hot weather can cause negative impacts on human health, agriculture, and natural environments. A heat wave — a spell of hot days with the mercury rising much higher than the average temperature — has been reported more frequently…

Hurricane Dorian marching slowly across Atlantic

The National Hurricane Center (NHC) in Miami reports that an Air Force plane is finding Dorian a “little stronger” as of the 8:00am EDT advisory put out today, Aug. 30, 2019.  Data from an Air Force Reserve reconnaissance aircraft indicate that…
