The present invention aims to provide a kind of spectrum of sunlight measuring method and device.
Fig. 1 is the process flow diagram of the spectrum of sunlight measuring method according to the embodiment of the present invention.As shown in Figure 1, this spectrum of sunlight measuring method comprises following step S102 to step S104:
Step S102, spectrum acquisition device obtains environment parameter.
The wave band periphery of spectrum of sunlight is 380 ~ 780 nanometers, and spectrum of sunlight is the spectrum that the vision of people can be experienced, and is generally divided into red, orange, yellow, green, blue, indigo, purple seven looks.The influence factor of the spectrum of sunlight in place to be measured comprises the longitude and latitude at place, place to be measured, the height above sea level in place to be measured, date, time, air and earth surface reflection situation.Wherein, longitude and latitude, height above sea level, date, time, atmospheric parameters and land surface parameters are called environment parameter, and environment parameter is the parameter affecting spectrum of sunlight.
The spectrum of sunlight of sunshine before entering earth atmosphere is referred to as earth external spectrum.Assuming that be vacuum environment from the sun to earth surface, then earth external spectrum can be obtained by satellite measurement data.Not considering in air and earth surface reflection situation, for same incident sunlight, the spectrum of sunlight of different location is not identical, even if in same place, the spectrum of sunlight of different time is not identical yet, and this phenomenon is mainly caused by the incident angle of daylight.Therefore, do not considering in air and earth surface reflection situation, when after the longitude and latitude in known place to be measured, height above sea level, date and time, the spectrum of sunlight in this place to be measured can pass through vacuum spectrum of sunlight pattern function (earth external spectrum, longitude and latitude, height above sea level, date, time) calculate.
In reality, Atmospheric components are complicated, higher to the influence degree of spectrum of sunlight, therefore, the measuring accuracy in order to improve spectrum of sunlight needs to consider with drag: the Rayleigh scattering model of air molecule, the absorbing model of ozonosphere, the absorbing model of mixed gas, the absorbing model of water vapor and aerocolloidal absorbing model.Wherein, the absorbing model of the Rayleigh scattering model of air molecule, the absorbing model of ozonosphere, the absorbing model of mixed gas and water vapor is relatively fixing, and aerocolloidal absorbing model is comparatively large by inside even from weather, and wherein, gasoloid refers to cloud, mist etc.The present invention aims to provide a kind of simple and rapid spectrum of sunlight measuring method, therefore, the present invention preferably uses the Rayleigh scattering model of fixing air molecule, the absorbing model of ozonosphere, the absorbing model of mixed gas and the absorbing model of water vapor, and aerocolloidal absorbing model is divided into fine, cloudy, cloudy, haze Four types, therefore, atmospheric parameters in the spectrum of sunlight measuring method of the embodiment of the present invention can use Atmospheric models function (the Rayleigh scattering model of air molecule, the absorbing model of ozonosphere, the absorbing model of mixed gas, the absorbing model of water vapor, aerocolloidal absorbing model) represent.
In addition, land surface parameters is also the important factor in order of spectrum of sunlight.Ground surface type can be divided into road surface, seawater, snowfield, meadow etc.Large-area high reflectance surface (such as seawater, snowfield etc.), the impact of land surface parameters on spectrum of sunlight is particularly evident.
