This is a 4-component net-radiation sensor that is used for
scientific-grade energy balance studies. The instrument has
separate measurements of solar (short Wave or SW) and Far
Infra-Red (Long Wave or LW) radiation. Major improvements
relative to comparable instruments include weight
(reduced), solar offsets in the LW signal (reduced), ease of
leveling (high because leveling assembly is included).
