The TIROS-N spacecraft, having a length of 3.71 m and a weight of 1421 kg. The four instruments of particular meteorological
importance are shown in the numbered boxes. 1. Visible and infra-red detector - discerns clouds, land-sea boundaries, snow and ice
extent and temperatures of clouds, earth's surface and sea surface. 2. Infra-red detector - permits calculation of temperatures profile
from the surface to the 10-mb level, as well as the water vapour and ozone contents of the atmosphere in cloud-free areas. 3. Device
for measuring temperatures in the stratosphere. 4. Device for measuring microwave radiation from the earth's surface which
supplements unit 2 in cloudy areas (
