Jim Banke, NASA [ Watch The Video: NASA Prepping HU 25C Guardian For ACCESS II Test Flights ] It's the season for sequels. Not only in Hollywood, but over the high desert of California as well. For the second time in as many years, NASA researchers beginning in early May will take to the skies with a DC-8 and other aircraft to conduct a series of flight tests designed to study the effects on emissions and contrail formation of burning alternative fuels in jet engines. And just...

NASA researchers have begun a series of flights using the agency's DC-8 flying laboratory to study the effects of alternate biofuel on engine performance, emissions and aircraft-generated contrails at altitude. The Alternative Fuel Effects on Contrails and Cruise Emissions (ACCESS) research involves flying the DC-8 as high as 40,000 feet while an instrumented NASA Falcon HU-25 aircraft trails behind at distances ranging from 300 feet to more than 10 miles. "We believe this study will...

Researchers have found that areas near commercial airports sometimes experience a small but measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions. The new study led by the National Center for Atmospheric Research (NCAR), is part of ongoing research that focuses on so-called hole punch and canal clouds that form when planes fly through certain mid-level clouds, forcing nearby air to rapidly expand and cool. This causes water droplets to...

Cirrus clouds are thin wisplike strands, sometimes accompanied by patches. Their shape and arrangement lead to their common name of "mare's tail". These clouds can be so extensive that they are virtually identical to one another and hard to tell apart. Sometimes high altitude convection produces another form of cirrus called cirrocumulus. Many cirrus clouds produce hair-like filaments made of heavy ice crystals that precipitate from them. This precipitation often indicates the difference in...
