infrared albedo
解釋
紅外反照率-
Roughly acquire optical depth of clear sky and clouds from radiation station data and routine meteorological data of land surface, and the study the relationship between clouds " physical character and radiation. obtain the relationship between surface and near - ground atmosphere, and then according to this estimate surface albedo and surface net. by analyzing the relationship between satellite visible spectra, infrared spectra, and water vapor spectra values and radiation, by means of radiation transfer theory, analyze and deducethe relationship between clouds and radiation, and establish relationships between satellite value and global radiation and net
通過衛星雲圖的計數值來判斷雲對輻射的作用，以此建立起它們之間的關系；利用地面觀測資料和常規資料來粗略求取晴空大氣和雲光學厚度，進而研究雲的物理屬性與輻射關系；簡單的獲取地表與近地面大氣之間的輻射關系，以此估算地表的反照率，和地表的凈輻射；分析了衛星可見光、紅外及水汽雲圖計數值和地面輻射之間關系，利用輻射傳輸公式來推倒和分析雲對輻射的關系，試圖建立起衛星測值與地表總輻射和凈輻射之間的關系，並將晴空和有雲的個例分開，分別建立並選出最佳模式，以此來估算地表的凈輻射和總輻射。 -
First, under the given boundary condition and reasonable simplified condition, this paper develops radiation transmitting equations in atmosphere applied in infrared waveband and visual light waveband from common equation of radiation transmitting. then, the formula between observation of satellite and net surface radiation is established according to the developed equations, from which it is found that net surface radiation is relative to sun zenith, land surface and cloud albedo, etc. at last, by using data of satellite visual light ( vis ), infrared 1 ( ir1 ), infrared 2 ( ir2 ) and water vapor ( ir3 ) channel, sun zenith and net surface radiation, a regression formula is built
本文從大氣中太陽輻射傳輸的一般性方程入手，引入邊界條件及簡化條件，推導出紅外波段和可見光波段的大氣輻射傳輸方程，由此建立起衛星觀測輻射與地面凈輻射的關系，文章還就衛星觀測到的輻射與雲量、雲高、雲的光學厚度、雲及地面反照率等之間的關系進行了理論分析，可以幫助更好地理解雲對地面凈輻射的影響。
