10 ways LASP is a leader in Earth and climate science

Earth rises over the surface of the Moon.

The Laboratory for Atmospheric and Space Physics (LASP) is renowned for being the world’s only academic research institute to explore every planet in our solar system (and beyond). But the planet that we study most closely is actually our home planet! About one-third of LASP’s current $1 billion research portfolio relates to studying Earth’s atmosphere… Read more »

LASP’s Hybrid Solar Reference Spectrum named new international standard for climate research

Earth’s primary source of energy is incoming radiation from our Sun. This “income” side of our planet’s energy budget sets the baseline for determining how quickly Earth is warming. When combined with measurements of the total amount of energy that’s emitted and reflected from our planet back into space, this information allows scientists to calculate… Read more »

New Earth-Observing Instrument Makes Successful Balloon Flight

In New Mexico on the morning of Aug. 18, a high-altitude balloon successfully carried the HyperSpectral Imager for Climate Science (HySICS) instrument to an altitude of 123,000 feet, above most of the Earth’s atmosphere, to reach space-like conditions and demonstrate new technologies for acquiring high-accuracy science measurements of the Earth.

Scientists use outgoing shortwave radiance, or the amount of sunlight scattered from Earth’s surface and atmosphere and reflected back toward space, as one of the key metrics for studying our planet’s dynamic climate. Watching these radiances over time helps researchers monitor and better understand the causes of environmental changes and global warming.
