Climate from Space vs SkyWindow

Satellites observing the Earth from space provide a clear picture of the health of our planet and the signs of climate change. This electronic book lets you take a closer look at the climate data being produced by the European Space Agency's Climate Change Initiative. Forty years of climate data are at your fingertips on interactive globes and maps. Use the data viewer to see how climate variables including ocean temperature, ice sheets, sea level, sea ice, carbon dioxide and soil moisture change through time. Play, pause, and step through the data; spin the world and zoom in; switch between globe and map views; compare one data set with another. Engaging and richly-illustrated text explains why measuring these parts of the Earth system is important for climate science, and describes what the climate data shows. Project scientists from across Europe explain their work in their own words in short video interviews. Features: • Interactive, animated globes with 17 key climate data sets • Scroll through time to see forty years of change • 130 illustrations, including satellite images, diagrams and animations • 14 interviews with project scientists • Over 16,000 words of text • 74 pages Requires: iPad 4th gen (2012), iPad mini 2 (2013), or later.

SkyWindow – Smart Planning for Astronomy & Astrophotography Many astronomy and astrophotography enthusiasts do not observe under perfect skies. Buildings, balconies, windows, and trees often limit the visible sky area. SkyWindow was designed exactly for these situations. SkyWindow helps you efficiently plan observations and astrophotography sessions based on your real visible sky window — ideal for smart telescopes and mobile observing setups. Whether you observe from a balcony, garden, rooftop window, or travel location, SkyWindow helps you determine when celestial objects become visible and worth capturing. Features • Tonight Quick access to the best observing opportunities for the current night, including visibility, timing, and sky conditions. • Catalogs Browse supported astronomy catalogs, inspect object details, and jump directly into observation planning. • Comet Hunter Plan observations for comets and asteroids with focus on motion, visibility, and timing. • Sites Manage observing locations such as balconies, gardens, windows, or remote travel sites. • Planner Build structured observation plans based on visibility windows, altitude, azimuth, and timing. • Mosaic Planner Prepare mosaic imaging projects for large deep-sky objects and advanced framing work. • Sky Journey Your personal observing journal with saved sessions, captured targets, favorites, retries, and observing history. Built for Modern Astronomy SkyWindow is designed for modern smart telescopes and efficient observation planning, especially for observers with limited sky visibility. Perfect for: • Smart telescopes • Balcony astronomy • Window observing • Mobile astrophotography • Travel observing • Deep-sky planning Plan smarter. Use your sky window efficiently.
