COPYRIGHT International Commission on IlluminationLicensed by Information Handling Services_ CIE 85 89 9006145 0003997 278 W 1. 1 INTRODUCTION It was decided to revise and update CIE Publication No.20 (TC-2.2)

23、 1972. The main reasons for this decision could be summarized as follows. It has become obvious that the solar spectral irradiance data on which the recommendations in the original document were based were no longer the most reliable. During the past decade a vast amount of new data has become avail

24、able both through modernized measurement techniques as well as improved modelling and parameterization methods. Contrary to the situation some years ago, the stage has now been reached where results for solar spectral irradiances at ground level as measured and those obtained by reliable modeling, u

The determination of the integrated irradiance of the extraterrestrial solar radiation, which was called “Solar Constant“ after Pouillet as early

31、as 1838, was originally based upon extrapolation of measured results at ground level. These were later followed by measurements from high mountain sites, balloons, aircraft and spacecraft. For obtaining ground level spectral irradiance data, use has been made of modelling, using extraterrestrial dat

32、a as a basis and taking into account atmospheric attenuation parameters. This has been supplemented by direct spectral measurements. The following recommendations are based upon extraterrestrial data of the World Meteorological Organization (WMO), which was mainly derived from the data of Labs and N

33、eckel, and of modeled data for atmospheric conditions based on the parameterization method according to Justus and Paris. 2. EXTRATERRESTRIAL SOLAR RADIATION 2.1 Extraterrestri al sol ar irradiance From the sun, the planet Earth receives electromagnetic as well as corpuscular radiation. The electrom

34、agnetic radiation of the sun is called solar radiation. The solar radiation incident on the upper boundary of the terrestrial atmosphere is called extraterrestrial sol ar radi at i on. Since the earth moves around the sun in an elliptical orbit, the ecliptic, one year, the distance from the sun to t

35、he earth and hence the irradiance of extraterrestrial solar radiation varies with time of the year. The actual value EJ of extraterrestrial solar irradiance on Julian day 3, (J = 1, ., 365) is given by during COPYRIGHT International Commission on IlluminationLicensed by Information Handling Services

The “squared distance reduction“ (R/RJ) is found in

(2) reads (R/RJ)2 = 1 t 0,0334.c0s (0,9856O.J - 2,7206“). (3) The “squared distance reduction varies from 1,0334 at perigee (on

39、 3 January) to 0,9666 at apogee (on 3 July) that is by about t 3.3% during the year. 2.2 The solar constant As mentioned, the extraterrestrial solar irradiance at mean earth-sun distance is called the solar constant. Direct measurements of the solar constant were taken by instruments aboard high-alt

For critical summaries, see Frhlich and Brusa i and Frhl

41、ich Z, for instance. As a result of these re-determinations of the solar constant, the Commission for Instruments and Methods of Observation of the World Meteorological Organization (WMO-CIMO) 3 agreed to adopt for meteorological purposes a value of the solar constant of Eo = (1,367 5 0,007) kW.m-*.

42、 (4) Any short term fluctuations of the solar constant are confined to the uncertainty limits given, i.e. to +. 0,5%. On the other hand, short or even longer term variations of the solar constant cannot be excluded on the basis of the present state of knowledge. 2.3 Spectral distribution When the sp

43、ectral distribution of extraterrestrial solar radiation is considered, the spectral irradiance reduced to mean earth-sun distance is usually meant. Thus, the integral over wavelength of the spectral extraterrestrial solar irradiance, EoA, yields the solar constant: The 1967-1969 measurements already

44、 mentioned were processed by Thekaekara 4, 5, 6, 71 to a recommendation for the extraterrestrial solar spectrum which yielded the value 1,353 kW.m-* for the solar constant. However, calibration and operational behaviour of the measuring instruments used were not completely above criticism so that be

45、sides Thekaekaras values, the results obtained by Labs and Neckel 8, from careful measurements at an 3600 m altitude observatory of the radiance of the suns center were also used. Since the dif- ferences in the ultraviolet and infrared spectral ranges of the two spectral distributions approximately

46、compensate each other, the value 1,358 kW.m-2 derived from Labs and Neckel for the solar constant came out very close to Thekaekaras value. 91 COPYRIGHT International Commission on IlluminationLicensed by Information Handling Services CIE 85 8 7006145 000400L 3T7 5 In order to obtain the mean radian
