LASSO Case Study: The Complex Travel of Solar Irradiance Through Cumulus Clouds
A pair of studies point to improved realism in calculating solar radiative transfer in model simulations Of all the energy the sun radiates into space, only about one-billionth reaches the Earth. But that still adds up to a staggering 173,000 terawatts (trillions of watts) a year, enough to power humankind’s energy needs about 10,000 times…

Best Practices for Aerial Research
ARM Aerial Facility helps build collaboration among U.S. agencies Numerous federal agencies and programs operate research aircraft, but they do not do it in a vacuum. Since the late 1990s, an organization has provided resources to senior management officials on airborne research issues. The Interagency Coordinating Committee for Airborne Geosciences Research and Applications (ICCAGRA) was…
