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.
On Sept. 29, 2013, a scientific balloon launched from the Columbia Scientific Balloon Facility in Fort Sumner, NM, flying an instrument that scientists hope will eventually establish a new long-term benchmark data set pertaining to climate change on the Earth.
The instrument, funded by a $4.7 million NASA Earth Science Technology Office Instrument Incubator Program contract, is intended to acquire extremely accurate radiometric measurements of Earth relative to the incident sunlight. Over time, such measurements can tell scientists about changes in land-use, vegetation, urban landscape use, and atmospheric conditions on our planet. Such long-term radiometric measurements from the HyperSpectral Imager for Climate Science (HySICS) instrument can then help scientists identify the drivers of climate change.
