A weather system moving slowly westward through the northwestern Hawaiian Islands has caused destructive flooding and mudslides and NASA's Global Precipitation Measurement mission or GPM satellite analyzed the heavy rainfall.
As summertime draws near, some people around the US will face annual water usage restrictions as water supplies become strained. But for those who live in arid climates year-round, water shortages are a constant concern. In these areas, residents must capitalize on even the smallest bit of moisture in the air. Now researchers report in ACS Applied Materials & Interfaces that they have developed a type of 'harp' to harvest fresh water from fog.
The first step after buildings collapse from an earthquake, bombing or other disaster is to rescue people who could be trapped in the rubble. But finding entrapped humans among the ruins can be challenging. Scientists now report in the ACS journal Analytical Chemistry the development of an inexpensive, selective sensor that is light and portable enough for first responders to hold in their hands or for drones to carry on a search for survivors.
With summer approaching, 'sea and sun' might conjure up images of a beach trip. But for scientists, the interactions of the two have big implications for the climate and for the formation of tiny droplets, or aerosols, that lead to clouds. In ACS Central Science, researchers demonstrate that sunlight can cause certain molecules at the ocean's surface to activate others, resulting in larger molecules that could affect the atmosphere.
On Sunday, April 15, a line of strong storms at one point stretched from the Florida Straits below the Florida Keys all the way up the East Coast and into Ohio. The Global Precipitation Measurement mission or GPM core satellite analyzed the severe storms as it passed overhead. GPM is a joint mission between NASA and the Japan Aerospace Exploration Agency, JAXA.
The remnant low pressure area that was once Tropical Cyclone Iris continues to linger in the South Pacific Ocean. NASA's Aqua satellite passed over the system and captured a visible image of it.
Researchers have measured CO2 emissions from fossil fuel use in California and compared them to reported emissions. This is the first time fossil fuel emissions have been independently checked for such a large area.
As expected, Tropical Cyclone Keni followed a track similar to Tropical Cyclone Josie and passed to the southwest of Fiji's main island of Viti Levu on April 10, 2018 (UTC).
Researchers have been debating whether nitrogen oxides (NOx) can affect levels of OH radicals in a pristine atmosphere but quantifying that relationship has been difficult. Now, Harvard researchers have found that accompanying the increase of NOx concentration from urban pollution, daytime peak OH concentrations in the rainforest skyrocketed, increasing by at least 250 percent. These increased levels of OH concentrations in the Amazon atmosphere could lead to changes in atmospheric chemistry, cloud formation, and rainfall
NASA satellite imagery showed that Tropical Cyclone Keni was being battered by vertical wind shear. NASA-NOAA's Suomi NPP satellite revealed that wind shear was pushing the clouds and storms associated with Keni to the southeast of the center.
