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…
Oldest lake in Europe reveals more than one million years of climate history
A deep drilling project at Lake Ohrid, situated at the border between Albania and North Macedonia and involving 47 researchers from 13 nations, has brought new insights into climate history to light. The team, headed by the geologist Professor Dr…
