NASA unveils spectacular suite of new global data products

...IS allows scientists to measure the differences in cloud optical properties for both water and ice clouds. The sensor can characterize the optical thickness of clouds and quantify the size of the particles within them. Moreover, MODIS is the first space-based sensor with a 1.37-m channel, which is particul...

...ty of the particles. If all are the same size, the cloud is likely to be artificial. But LIDAR doesn't reveal the type of bacteria. So researchers shifted to ultraviolet wavelengths, which can yield signals unique to different pathogens up to 12 kilometres away. Still, the system cannot distinguish betwee...

Assaulting the mosquitos sense of smell

...emissions such as carbon dioxide. We all produce a cloud of chemicals and mosquitoes can track the odor trail that we leave for quite a distance, says Zwiebel. Many of these chemical cues are created by the bacteria that cover our bodies. Studies have shown that fewer mosquitoes attack a person after they ...

In theory, average tropical surface temperatures should not climb much above 30 C (86 F). Paleoclimate studies have previously shown that some subtropical locations on Earth regularly experienced se...

Climate monitoring goes mobile

Changes in rainfall patterns spur plant growth, carbon absorption across U.S.

... data over that time period also show increases in cloud cover, minimum temperatures, soil moisture and stream flows, which are all signs of a changing hydrologic cycle. Whether or not shifting rainfall patterns result in a positive uptake of carbon by land ecosystems depends on complex interactions that ...

What a difference a decade makes
