Meteorology. Air temperature measurements. Test methods for comparing the performance of thermometer shields/screens and defining important characteristics Ingestion-build-48974 Annex A (Normative) Aggregate correction1 Scope This International Standard defines characteristics of a thermometer shield screen. It also defines test methods to inter compare the behaviour of different screen designs. Although screens are usually used for both air temperature and humidity measurements, this International Standard is applicable only to temperature measurements. Both naturally and artificially ventilated screens are considered.
