Modis or moderate resolution imaging spectroradiometer is a key instrument aboard the terra originally known as eos am 1 and aqua originally known as eos pm 1 satellites. With its sweeping 2 330 km wide viewing swath modis sees every point on our world every 1 2 days in 36 discrete spectral bands. The top row shows orbital tracks the middle row shows visible imagery and the bottom row shows corresponding level 2 swath snow extent data.

Historical imagery is sourced from microsoft and esri. The winning essay was submitted by sasha jones of brentwood missouri. Terra s orbit around the earth is timed so that it passes from north to south across the equator in the morning while aqua passes south to north over the equator in the afternoon.
