Zoom-in to plasmapause-induced TEC enhancement - April 2001 (Version 2) |
| Abstract |
Space weather events which disturb the plasmapause (displayed here as a green surface enclosing the Earth) can propagate down to the Earth's ionosphere. There they enhance the ionosphere electron content which can disrupt radio signals from satellites. This movie is a variation on animation ID 3311 with slightly different camera motions. |

…
| Title |
Erythemal Index for August 2000 through July 2001: Full Earth (With Dates) |
| Abstract |
The Erythemal Index is a measure of ultraviolet radiation (UV) at ground level on the Earth. UV exists to the left of the visible spectrum and is divided into three components (UV-A, UV-B and UV-C). UV-B (290-320 wavelengths) is the most dangerous form of UV radiation that can reach ground level. Atmospheric ozone shields life at the surface from most of the harmful components of solar radiation. Chemical processes in the atmosphere can effect the level of protection provided by the ozone in the upper atmosphere. This thinning of the atmospheric ozone in the stratosphere leads to elevated levels of UV-B at ground level and increases the risks of DNA damage in living organisms. |

| Title |
Creating the Tamarisk Habitat Suitability Map (for General Use) |
| Abstract |
The spread of invasive species is one of the most daunting environmental, economic, and human-health problems facing the United States and the World today. It is one of several grand challenge environmental problems being addressed by NASA's Science Mission Directorate through a national application partnership with the US Geological Survey. NASA and USGS are working together to develop a National Invasive Species Forecasting System (ISFS) for the management and control of invasive species on Department of Interior and adjacent lands. The system provides a framework for using USGS's early detection and monitoring protocols and predictive models to process MODIS, ETM+, ASTER and commercial remote sensing data. It can also be used to create on-demand, regional-scale assessments of invasive species patterns and vulnerable habitats. The first step in this process is to collect relevant satellite data which can then be used to derive a Tamarisk Habitat Suitability Map. By combining satellite observed annual vegetation cycles with landcover classification data the likely habitat for Tamarisk can be derived. |

Blue Marble - A Seamless Image Mosaic of the Earth (WMS) |
| Abstract |
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. Much of the information contained in this image came from a single remote-sensing device-NASA's Moderate Resolution Imaging Spectroradiometer, or MODIS. Flying over 700 km above the Earth onboard the Terra satellite, MODIS provides an integrated tool for observing a variety of terrestrial, oceanic, and atmospheric features of the Earth. The land and coastal ocean portions of these images are based on surface observations collected from June through September 2001 and combined, or composited, every eight days to compensate for clouds that might block the sensor's view of the surface on any single day. Two different types of ocean data were used in these images: shallow water true color data, and global ocean color (or chlorophyll) data. Topographic shading is based on the GTOPO 30 elevation dataset compiled by the U.S. Geological Survey's EROS Data Center. |

| Title |
Lake Chad 2001 |
| Abstract |
Sweep of Lake Chad, February 2001. Located on the edge of the Sahara and bordering four countries--Chad, Cameroon, Nigeria, and Niger--the immense area of this land locked lake has nearly disappeared in recent years. Persistent drought has caused the lake to drop from its former sixth place position in the list of world's largest lakes, it is now one tenth its former size. The basin of the lake is not naturally deep, so the surface area of the lake tended to spread out, keeping the total depth to little more 23 feet (7 meters). In recent years, rainfall patterns have begun to change, and tributaries to Lake Chad have not been refilling the basin as rapidly as they used to. The lush, productive flora and fauna fed by the wetlands of the shallow lake have suffered as a result. This has led to significant changes for various communities of people that live in the vicinity of the Lake. While for some the now exposed lake bed has enabled new land to be cultivated, much of the available fresh water that might have been used for irrigation is no longer dependable. As rainfall rates appear to be declining year after year, people living nearby develop even greater dependence on the lake, draining it even faster. |

One Year of Terra/CERES data (Reflected Solar Radiation) Daily data |
| Abstract |
This animation displays a little over one year of Terra/CERES data (March 1, 2000 to May 25, 2001) at one day resolution. The data are 2.5 degree resolution. The band is reflected solar radiation (often referred to as 'shortwave' in the literature). Bright areas correspond to cloudtops or snowcover. |

Aerosols and Warming Change

| Title |
Aerosols and Warming Change with Time - Version 2 |
| Abstract |
As the aerosol content and solar heating change with time, the atmosphere and the Earth's surface experience different warming and cooling. This animation displays a time series of the INDOEX region with 8-day averages showing aerosol and solar reflectance (albedo) data from the Terra satellite. From these, we see how these inputs generate warming of the atmosphere (Atmospheric Forcing - red regions) and cooling of the surface (Surface Forcing - dark regions). Areas of missing data (due to clouds, etc.) are either black or transparent. |
