For the last few decades, a series of satellites have used lasers to radically improve our understanding of earth and how it is changing over time. This technology, satellite ラーメンベット 入金ボーナス, has quantified data on critical climate issues such as melting ice, sea level changes, carbon levels in forests around the globe and the amount of aerosols in the sky.
In new ラーメンベット 入金ボーナス, an all-woman group of authors from five different institutions published an anthology of all the important data unearthed by laser altimetry over the last two decades. As these missions remain ongoing, the ラーメンベット 入金ボーナス illustrates the impact of this technology.
These ラーメンベット 入金ボーナス to play an important role in understanding the changing nature of our climate and planet as a whole.
"We know from 20 years of observation that this is a great technology that can tell stories about our planet through data with unprecedented accuracy and resolution," said Lori Magruder, an associate professor in the ラーメンベット 禁止ゲーム of Engineering's Department of Aerospace Engineering and Engineering Mechanics, and the lead author on the ラーメンベット 入金ボーナス published in Nature Reviews Earth & Environment.
How it Works: A laser altimeter is primarily used to learn ラーメンベット 入金ボーナス the topography – the height and shape – of an area. A satellite shoots a laser beam from space that illuminates a certain area and then bounces back. The topography of the target area can be determined by how far the laser travels and how long it takes to bounce back.
Background: The original ラーメンベット 入金ボーナス mission – Ice, Cloud and land Elevation Satellite (ICESat) – ran from 2003 to 2009. Its descendant, ICESat-2, launched in 2018 and remains active today. These missions are complemented by the Global Ecosystems Dynamic Investigation (GEDI) mission, which also remains active.
The University of Texas at Austin has a rich history of involvement in laser altimetry missions. Bob Schutz, a former aerospace engineering faculty member, was chosen as the original science team lead on ICESat. Magruder and Amy Neuenschwander, a co-author on the paper and senior ラーメンベット 入金ボーナス scientist at UT's Center for Space ラーメンベット 入金ボーナス, are both part of the science team for ICESat-2, a group Magruder previously led for a decade.
Why It Matters: After ICESat-2 and GEDI, no further ラーメンベット 入金ボーナス missions are on the books. Showing the effectiveness of this technology is critical to making sure support remains strong for its continued development and deployment.
Every 10 years, the National Academies of Sciences, ラーメンベット 入金ボーナス and Medicine publish the Decadal Survey for Earth Science and Applications from Space, which will help shape science priorities and guide agency investments into the next decade. The survey, sponsored by NASA, NOAA, and the USGS, is driven by input from the scientific community and policy experts.
The next survey is coming up in 2027, and will certainly play a role in the future of space missions and ラーメンベット 入金ボーナス.
"We want to make sure the scientific community understands the impact these missions have made," said Neuenschwander. "These ラーメンベット 入金ボーナス to play an important role in understanding the changing nature of our climate and planet as a whole."
Co-authors on the paper include Sinead Farrell and Laura Duncanson of the University of Maryland, Bea Csatho of the University of Buffalo, Sahra Kacimi of the Jet Propulsion Laboratory and Helen Amanda Fricker of the Scripps Institution of Oceanography at UC San Diego.
