abstract = "Measure atmospheric longwave irradiance. ABSOLUTE measurement traceable to International System of Units (SI). To date, Interim world reference traceable to blackbody (not sky/atmosphere), World Infrared Standard Group (WISG). InfraRed Integrating Sphere (IRIS) Developed by the World Radiation Center (PMOD) is traceable to blackbody irradiance. ACP is self-calibrated radiometer using heat substitution like Absolute Cavity Radiometer (ACR) that is self-calibrated radiometer using electrical substitution to measure solar irradiance. ACP is a contribution to develop the world reference with traceability to SI, using the outdoor irradiance as the source, instead of blackbody.",
