Looking at clouds from space, it can be hard to tell what they’re made of – particles of ice and water.

00:00:04,210 --> 00:00:08,220

00:00:08,220 --> 00:00:12,230

00:00:12,230 --> 00:00:16,230
The different makeups – and the number - of these clouds play an important role in weather and climate,

00:00:16,230 --> 00:00:21,030


6
00:00:21,030 --> 00:00:25,570
so understanding them better will improve models and forecasts.

00:00:29,570 --> 00:00:33,570
A tiny satellite has been orbiting Earth for a year, taking measurements of these particles 

9
00:00:33,570 --> 00:00:37,980
and creating an unprecedented new map of these hard-to-study ice clouds.

00:00:37,980 --> 00:00:42,120


11
00:00:42,120 --> 00:00:46,120
The satellite, IceCube, launched in May 2017 and was designed for a 3-month mission.

12
00:00:46,120 --> 00:00:50,240


13
00:00:50,240 --> 00:00:55,320
It’s been flying for a full year, collecting data for a never-before-seen view of ice clouds around the planet.

00:00:55,320 --> 00:00:59,510
