An Evaluation of an Infrared/Resistance Temperature Device for Air/Sea- Surface Temperature Measurements

Abstract

An infrared/resistance temperature device (IR/RTD) and a hand-held psychrometer were used at sea for 12 days, onboard the USS Ranger (CV 61), to gather air and sea-surface temperatures. Although not supported by the evaporation duct height calculations of this test period, the clearly artificial trend in sea-surface temperature readings reported from the seawater intake makes the IR/RTD the preferred instrument to measure sea-surface temperatures. While tests reported in this document were primarily setup to see if the IR/RTD is practical for use in evaporation duct calculations, two other uses of the device were identified: (a) it was determined that sea-surface temperatures as an aid in forecasting the time fog will dissipate, and (b) it was used to sense the temperatures of sensitive electronic equipment, thus permitting operators to safely turn off their equipment when the maximum operating temperature was reached.
