Pyranometer offsets triggered by ambient meteorology: insights from laboratory and field experiments
Publikováno v:
Atmospheric Measurement Techniques, Vol 10, Iss 3, Pp 1169-1179 (2017)
This study investigates the effects of ambient meteorology on the accuracy of radiation (R) measurements performed with pyranometers contained in various heating and ventilation systems (HV-systems). It focuses particularly on instrument offsets obse

Integral plume models harbor a fundamental, often significant error because the standard implementation of control volumes, or elements, is inconsistent with the overall geometry of the problem. The error, called the negative volume anomaly, occurs i
