In a first, researchers from the University of California, Irvine – as well as Switzerland’s University of Zurich, IBM Research-Zurich and UC Santa Cruz – have obtained direct images of dissolved organic carbon molecules from the ocean, allowing better analysis and characterization of compounds that play an important role in the Earth’s changing climate.

Artificial Intelligence Can Identify Wildlife as Accurately as Humans
Motion-sensor cameras are increasingly being used to track wildlife across the globe, from tigers in India to aardvarks in Africa. But combing through the millions of images captured by these systems is a time-consuming task. Now, scientists have discovered that artificial intelligence is as effective as human volunteers — and much faster — at identifying species in these largely untapped photo repositories.
NASA Analyzes No. Indian Ocean Rainfall of Soaking Separate Cyclones
NASA analyzed rainfall in two tropical cyclones that developed in the Northern Indian Ocean, each bringing heavy rainfall. Within a week, separate cyclones, Tropical Storm Sagar and Cyclone Mekunu, hit Somalia and nearby Oman, respectively, and both dropped heavy rainfall in a region that is not accustomed to it.
20 Years of Earth Data Now at Your Fingertips
Powerful Earth-observing instruments aboard NASA’s Terra and Aqua satellites, launched in 1999 and 2002, respectively, have observed nearly two decades of planetary change. Now, for the first time, all that imagery — from the first operational image to imagery acquired today — is available for exploration in Worldview.
UNH Researchers Shine a Light on More Accurate Way to Estimate Climate Change
It doesn’t matter if it’s a forest, a soybean field, or a prairie, all plants take up carbon dioxide during photosynthesis – the process where they use sunlight to convert water and carbon dioxide into food. During this changeover, the plants emit an energy “glow” that is not visible to the human eye, but can be detected by satellites in space. Now, researchers at the University of New Hampshire have taken that one step further. By using satellite data from different major land-based ecosystems around the globe, they have found that the photosynthesis glow is the same across all vegetation, no matter the location. This first-of-its-kind global analysis could have significance in providing more accurate data for scientists working to model carbon cycle and eventually help better project climate change.
NASA Finds Some Fragmented Strength in Tropical Depression 05W
NASA obtained an infrared look at Tropical Depression 05W as it continued moving through the South China Sea. NASA's Aqua satellite found very cold cloud top temperatures and strong storms in fragmented thunderstorms mostly east of 05W's center.
NASA's Aqua satellite passed over Tropical 05W on June 5 at 2:05 a.m. EDT (0605 UTC) and analyzed the storm in infrared light to reveal cloud top temperatures. The MODIS or Moderate Resolution Imaging Spectroradiometer instrument aboard NASA's Aqua satellite revealed some cloud top temperatures in a fragmented band of thunderstorms were as cold or colder than minus 70 degrees Fahrenheit (minus 56.6 degrees Celsius). NASA research indicates very cold cloud tops with the potential to generate very heavy rainfall. The strongest storms all appeared to be over open waters in the Gulf of Tonkin and northern South China Sea.
