![]() Retrieval and local caching of that data is therefore a primary feature of World Wind. World Wind works with enormous quantities of data and information, all of which exist primarily on remote data Implementations and easily integrate them into World Wind. This allows application developers to create their own Most of World Wind's components are defined by interfaces. Implementations of Model, SceneController and View. Wind provides several Globe objects representing Earth, Mars and the Earth's moon, and provides basic Objects implementing a particular interface may be used wherever that interface is called for. The objects implementing the above interfaces may be those provided by World Wind or those created by applicationĭevelopers. The scene controller subsequently manages the display of the globe and its layers inĬonjunction with an interactive View that defines the user's view of the planet. Model They then pass that model to a SceneController that displays the globe and its layers in a ![]() In typical usage, applications associate a Globe and several Layers with a View - interactively controls the user's view of the model.SceneController - controls the rendering of a Model.Model - aggregates a Globe and the Layers to apply to.Layer - applies imagery or information to a Globe.Globe - represents a planet's shape and terrain.In addition to WorldWindow, there are five major World Wind interfaces. Swing/AWT and, in the future, SWT-Eclipse. Toolkit-specific implementations of the interface are provided for The API is defined primarily by interfaces, soĬomponents can be selectively replaced by alternative components. The World Wind components are extensible. Applications use World Wind by placing one or more WorldWindow components World Wind is a collection of components that interactively display 3D geographic information within JavaĪpplications. To understand what drives variability in the ionosphere requires a careful look at a complicated system that is driven by both terrestrial and space weather.ICON will help determine the physics of our space environment and pave the way for mitigating its effects on our technology, communications systems and society.The view package contains implementations, and support for implementations of the In order to understand this complicated region of near-Earth space, called the ionosphere, NASA has developed the ICON mission. ![]() ![]() Variations there can result in distortions or even complete disruption of signals. These winds can change on a wide variety of time scales - due to Earth's seasons, the day's heating and cooling, and incoming bursts of radiation from the sun.This region of space and its changes have practical repercussions, given our ever-increasing reliance on technology - this is the area through which radio communications and GPS signals travel. In this region, the tenuous gases are anything but quiet, as a mix of neutral and charged particles travel through in giant winds. Credit: NASA/GSFC/CIL || The Ionospheric Connection Explorer will study the frontier of space: the dynamic zone high in our atmosphere where terrestrial weather from below meets space weather above. The electric field permeates through the upper atmosphere and pushes plasma (pink) upwards and downwards like a fountain at 370 miles above Earth’s surface.īeauty pass showing ICON observing the ionosphere. These winds eventually form an atmospheric tide that propagates up through the atmosphere.Īt 60-95 miles above the ground, winds associated with atmospheric tides (white arrows) move the chunky, charged ions and separate them from the small, negatively charged electrons, forming an electric field (blue line) in the dynamo region, near the bottom of the ionosphere. The heating and cooling pushes wind patterns out and towards regions where clouds are forming. In this region, daily cycles of cloud formation put energy into the atmosphere that, in turn, create a daily cycle of heating and cooling. One source of atmospheric tides is created above rainforest regions around Earth’s equator such as the Amazon rainforest. ![]()
