摘要
为正确估计表面温度,本文提出了一个用Eppley大气辐射表在现场测定比辐射率的一个简单方法。辐射表的指示温度必须对实际大空热辐射与表面比辐射率做校正。根据1985年12月—1986年1月在西藏那曲所做观测的比较,发现辐射温度与水银温度表的温度之间差值大部分在2—4℃以内。
A simple methord of determing emissivity of surface using Eppley pyrgeo-meter in situ in order to evaluate surface temperature is presented. The indicated temperature of radiometer need corrections for actual sky thermal radiance and for true surface emissivities. Based on comparisons between radiation temperature and surface mercury-thermometer temperature at Nagqu, northern Tibetan during December 1985-January 1986, it was observed that their differences were mostly within 2-4 ℃.
