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.
