RA01 is a market-leading 2-component radiometer, primarily used in scientific-grade energy balance and surface flux networks. It offers 2 separate measurements of global solar and downward longwave radiation with a pyranometer and a pyrgeometer, respectively. Product features include a modular design, low weight, easy leveling, and low solar offsets in the longwave measurement. RA01’s unique capability to heat the pyrgeometer reduces measurement errors caused by dew deposition. When combined with estimates of solar albedo and local surface temperature, this instrument can also be used for estimation of net radiation. The advantages of this approach are cost reduction and independence from local surface properties.
