Description:

Space Station Sails Across the SunA NASA photographer captured the ISS as it passed directly between the Sun and Earth. Earth A Photo-Essay NASA has a unique vantage point for observing the beauty and wonder of Earth and for making sense of it. The images in this book tell a story of a 4.5-billion-year-old planet where there is always something new to see. Channeling a Bloom Unusually clear skies and persistent, unseasonable heat may have set the stage for a large and persistent blooms of phytoplankton in the waters around England. Farewells Leg 4 scientists and crew with the MOSAiC expedition have finally headed for the Arctic ice pack. Published Jun 25, 2020 inNotes From the Field Mission: Biomes Have you ever wondered what it would be like to live in a different part of the world? What would the weather be like? What kinds of animals would you see? Which plants live there? By investigating these questions, you are learning about biomes. Published Oct 5, 2000 Land Life Research Roundup: Depicting Change Across Earth's Frozen Places A series of recent research papers shows that we know more than ever before about the ice on our land and covering the seas. Here’s a look at some of the notable findings. Published Jun 15, 2020 inEarth Matters Total Rainfall These maps depict monthly total rainfall around the world. Rainfall is the primary source of fresh water for humans, plants, and animals. Rain also moves heat between the atmosphere, oceans, and land. Atmosphere Pathfinder for COVID-19 The COVID-19 Data Pathfinder provides links to datasets that can be used to research changing environmental impacts from modified human behavior patterns during the global pandemic. Published Jun 8, 2020 inEarth Matters Water Snow Cover Snow and ice influence climate by reflecting sunlight back into space. When it melts, snow is a source of water for drinking and vegetation; too much snowmelt can lead to floods. These maps show average snow cover by month. Snow and Ice Water Vapor These maps show the average amount of water vapor in a column of atmosphere by month. Water vapor is the key precursor for rain and snow and one of the most important greenhouse gases in the atmosphere. Atmosphere Sea Surface Temperature Anomaly These maps depict how much hotter or cooler an ocean basin was compared to the long-term average. Temperature anomalies can indicate changes in ocean circulation or the arrival of patterns like El Ni o and La Ni a. Heat Water Vegetation Greenness is an important indicator of health for forests, grasslands, and farms. The greenness of a landscape, or vegetation index, depends on the number and type of plants, how leafy they are, and how healthy they are. Land Life Applied Sciences Collection NASA satellites and sensors constantly take the pulse of our planet. Researchers apply those observations on local and regional scales to better manage things like food and water supplies, health, safety, land use, and ecosystems. Published May 1, 2020 Human Presence Remote Sensing Carbon Monoxide When fuels such as coal, wood, and oil burn incompletely, they produce carbon monoxide. The gas is spread by winds and circulation. These maps show monthly averages of CO in the lower atmosphere. Atmosphere
