Beginning 1 October , Landsat data could be downloaded freely. This had an immediate impact: the number of scenes downloaded increased manifold during the next few years. By the mids Earth-observation data were of sufficiently long duration to allow scientists to look at interannual variability.
Under Trump, NASA May Turn a Blind Eye to Climate Change
This is when the research community really started making significant use of these data. Today, the space agencies participating in CEOS have more than Earth observation missions in orbit www. Satellite observations were integrated with field campaigns that combined surface-based and airborne observations. Other examples include the Boreal-Ecosystem-Atmosphere study in the US and Canada ; the Large-scale Biosphere-Atmosphere Experiment in Brazil that began in but for which planning started in ; see box ; the polar ozone airborne campaigns in the Antarctic and Arctic , ; and Global Troposphere Experiment GTE series of airborne campaigns going back to and continuing into the early 21st century.

The resulting 1km AVHRR data set was one of the main driving forces in improvements in global land data sets. Subsequent work resulted in the development of data principles in support of the operational use of satellite data for public benefit. The first freely available medium-resolution imagery dates to , and access to Earth-observations data has improved greatly since then.
Go from Quantum to Cosmic
In particular, the decision in to release the current and archived Landsat data encouraged far more people to use the data than before Figure 1. Figure 2. We came to measure the increasing rate of ice loss from the polar regions and regional rates of sea-level rise.
IGBP — by virtue of its ability to bring together different disciplines, communities and nations — was at the forefront of the development of models that combined physics, chemistry and biology. IGBP not only provided a forum for model development but also facilitated inclusive model-model and model-observation intercomparison activities. The space agencies and scientific community all owe a debt to those who contributed their time and effort towards making IGBP such a valuable contributor to, and resource for, the Earth-system science community.
Its goals are to understand how Amazonia functions as a regional entity in the Earth system and how those functions are responding to ongoing changes in land use and climate. Given this linkage, the LBA can be understood as a product of IGBP in conjunction with other research programmes that operated in the region.
Its institutional relationship with the IGBP research effort on global change directly affected the formulation of its research questions, design and institutional arrangement. LBA scientific activities cover seven themes: 1 land-use and land-cover change, 2 physical climate, 3 carbon dynamics, 4 biogeochemistry, 5 atmospheric chemistry, 6 land-surface hydrology and aquatic chemistry, and 7 human dimensions.

In recent years Republican lawmakers have sought budget cuts to climate change—related Earth science programs at all three agencies. Because he is not a member of the transition team now laying the groundwork for a Trump administration, Walker says he cannot speculate about what near-term space policy decisions the president-elect will soon make. Even so, he insists that climate-change denial is not behind the platform he laid out for the Trump campaign, and he notes that he co-sponsored the first climate bill ever passed into law—the National Climate Program Act signed by Pres.
Jimmy Carter in There have been concerns among some of us that those sorts of NASA programs were robbed in order to concentrate on Earth science, and we want to reestablish the emphasis of NASA itself on the things that go beyond Earth orbit and Earth-observation activities.
They and the satellites they use also provide critical insights for a broad range of public and private activities that enjoy bipartisan support, such as weather forecasting, agricultural reporting, and disaster response and preparedness. But distinguishing them as unrelated to a phenomenon as multifaceted and omnipresent as climate change is difficult, and perhaps foolhardy.
Conducted once every 10 years, this poll of U. Earth scientists produces a wish list of future research priorities to guide policy makers setting the multibillion-dollar budgets for NASA and other science agencies.

It will likely include recommendations for new generations of satellites and instruments to monitor Earth with unprecedented clarity as well as suggestions meant to lower costs. For the time being, the U. Lee Billings is a senior editor at Scientific American.
