Short summary

We launched the DSCOVR spacecraft to an orbit located near the earth–sun gravitational plus centrifugal force balance point known as Lagrange 1. One of the earth-viewing instruments, EPIC, measures earth-reflected radiances in 10 wavelength channels ranging from 317.5 nm to 779.5 nm. We use the UV channels to retrieve O₃ and scene reflectivity, and to derive the first measurement of erythemal flux (sunburn) from sunrise to sunset at the earth's surface.
