چکیده
This spectacular “blue marble” image is the most detailed true-color image of the entire Earth to date. Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (.386 square mile) of our planet. These images are freely available to educators, scientists, museums, and the public. This record includes preview images and links to full resolution versions up to 21,600 pixels across.

A trading-space-for-time approach to probabilistic continuous streamflow predictions in a changing climate – accounting for changing watershed behavior
Projecting how future climatic change might impact streamflow is an important challenge for hydrologic science. The common approach to solve this problem is by forcing a hydrologic model, calibrated on historical data or using a priori parameter estimates, with future scenarios of precipitation and temperature. However, several recent studies suggest that the climatic regime of the calibration ...
متن کاملPredictability of Seasonal Streamflow in a Changing Climate in the Sierra Nevada
The goal of this work is to assess climate change and its impact on the predictability of seasonal (i.e., April–July) streamflow in major water supply watersheds in the Sierra Nevada. The specific objective is threefold: (1) to examine the hydroclimatic impact of climate change on precipitation and temperature at the watershed scale, as well as the variability and trends in the predictand (i.e....
متن کاملAgroecosystem Analysis of the Choke Mountain Watersheds, Ethiopia
Tropical highland regions are experiencing rapid climate change. In these regions the adaptation challenge is complicated by the fact that elevation contrasts and dissected topography produce diverse climatic conditions that are often accompanied by significant ecological and agricultural diversity within a relatively small region. Such is the case for the Choke Mountain watersheds, in the Blue...
متن کاملSustaining the Earth’s Watersheds– Agricultural Research Data System: Overview of development and challenges
The USDA Agricultural Research Service has supported watershed research since the 1930s. Data from USDA Agricultural Research Service watersheds have been disseminated independently at each location, hindering multi-site analyses. A virtual team spanning diverse organizational units developed a web-based system, Sustaining the Earth’s Watersheds– Agricultural Research Data System (STEWARDS) tha...
متن کاملWater Stress Projections for the Northeastern and Midwestern United States in 2060: Anthropogenic and Ecological Consequences
Future climate and land-use changes and growing human populations may reduce the abundance of water resources relative to anthropogenic and ecological needs in the Northeast and Midwest (U.S.). We used output from WaSSI, a water accounting model, to assess potential changes between 2010 and 2060 in (1) anthropogenic water stress for watersheds throughout the Northeast and Midwest and (2) native...
