Test Reference Year (TRY) (DSI-9706)Entry ID: gov.noaa.ncdc.C00049
Abstract: Test Reference Year is historical digital data set DSI-9706, archived at the National Climatic Data Center (NCDC). Efficient heating and cooling is largely dependent on building design and on the design of the heating and cooling system. Comparison of heating and air-conditioning systems in a locale requites a consideration of the effects of the weather. This weather information must be in great ... detail. The American Society of Heating, Refrigeration, and Air- conditioning Engineers, (ASHRAE) established a task group on energy requirements for heating and cooling large structures. Simultaneously, is the interest of energy conservation, the National Bureau of Standards (NBS) and the National Oceanic and Atmospheric (NOAA) were attempting to develop climatological data packaging most useful for building design applications. Joining forces, the three groups established a working group to develop the concept of a TRY. TRY would consist of hourly weather data values for a selected reference year to be used by engineers in a given area to compare different heating and air- conditioning systems in the same building or in different buildings. At the same time, the Federal Energy Administration (FEA)--as a member of the Steering Group on Climatic Conditions and Reference Year of the NATO Committee on Challenges of Modern Society--was also working on the problem. Consolidation of both efforts resulted in the development of a selection process for the Test Reference Tear, an international format for presentation of the TRY data, and TRY calculations for 60 cities within the U.S. The ASHRAE approved procedure was chosen for selecting a TRY. The principle of selection is to eliminate years in the period of record containing months with extremely high or low mean temperature until only one year remains. The period of record examined for 59 U.S. stations is 1948-1975. The 60th station, Portland, Oregon, has a period of record of 1949-1975.
Purpose: To make a wide range of climatic data available to researchers and the public.
