Gradescope vs Atmosphere AR

Students, upload your assignments to Gradescope more easily than ever before! If your instructor uses Gradescope for your assignments, you can now upload your submission with our mobile app. After installing and opening the app, login to see your Gradescope courses and assignments. To upload a submission, click on the assignment in the “Not Submitted” tab and either “Select File” to select an existing file from your device or “Scan” all pages of your completed work using your iPhone’s camera. Once you submit your file(s), for templated assignments, you’re all set. For variable-length assignments, “Assign pages” to indicate where your answer for each question appears within your submission. It’s that easy! After confirming, your assignment then moves to the “Submitted” tab. If needed, you can resubmit your assignment until the due date your instructor set has passed. Once it is graded and grades are published for the assignment, it then moves to the “Graded” tab. Note: For V1 of the app, you will be directed to our mobile website for any advanced functionality, including viewing feedback and submitting timed, programming, or online assignments. Stay tuned for future updates that will allow you to do even more with our mobile app!

Atmosphere AR is an educational augmented reality app that brings atmospheric science to life. Point your iPhone camera at a printed world map or globe to visualize how Earth's atmosphere actually moves. WIND CIRCULATION MODELS Explore two foundational models of global atmospheric circulation with animated particles and stream trails: - Single Cell Model — the simplest model of global circulation, showing a single continuous loop of rising and falling air per hemisphere - Three Cell Model — Earth's actual circulation pattern, showing the Hadley, Ferrel, and Polar cells with realistic Coriolis-deflected trade winds, westerlies, and polar easterlies - ERA5 Real Data — compare theoretical models against actual measured wind data from ECMWF reanalysis, updated monthly TEMPERATURE OVERLAY Explore surface and upper atmosphere temperatures from ERA5 reanalysis data. Use the pressure level slider to move through the atmosphere from the warm surface layer (1000 hPa) up to the cold upper troposphere (100 hPa, ~16km altitude). LIGHTNING OVERLAY View global lightning flash frequency from GOES-18 Geostationary Lightning Mapper satellite observations. See how lightning concentrates near the ITCZ equatorial convergence zone — connecting directly to the Hadley cell circulation pattern. VIRTUAL GLOBE Scan a globe tracker to spawn an interactive 3D Earth in your space. Drag with one finger to rotate, pinch with two fingers to scale. All wind, temperature, and lightning overlays work on the globe as well as the flat map. EDUCATIONAL DESIGN Built for students, educators, and anyone curious about Earth's atmosphere. The info panel explains what you are seeing — including the science behind the Coriolis effect, cell boundaries, and how real atmospheric data compares to theoretical models.
