A Field Comparison among a Domeless Net Radiometer, Two Four-Component Net Radiometers, and a Domed Net Radiometer

Abstract

The Kipp & Zonen NR-Lite is a newly designed domeless net radiometer. In preparation for the Oklahoma Atmospheric Surface-layer Instrumentation System (OASIS) Project, the NR-Lite was rigorously field tested for over eight months during 1998. Seven NR-Lites were compared to an Eppley four-component PSP/PIR net radiometer system, a Kipp & Zonen four-component CNR1, and a REBS Q*7.1. Measurement problems associated with calibration, precipitation, cosine response, and wind-induced error were examined. Results conclude that the NR-Lite is well-suited for experiments where remote, long-term measurements of net radiation are required.
