| Although the solar simulator provides a higher spectral irradiance throughout the UV, its spectrum differs from natural sunlight. |
|
| Consider the task of measuring the spectral content of output irradiance from a solar simulator. |
|
| An additional advantage of this method is that UV-B irradiance can be determined at any depth within a leaf. |
|
| When imaging large areas, this requirement for a high photon irradiance presents a significant technical challenge. |
|
| In the preillumination experiments the cells were exposed to lights of different irradiance, dose and direction. |
|
| Horizontal-surface irradiance depends on earth-sun distance, solar elevation angle and atmospheric transmissivity. |
|
| The scene observed in false color illustrates the incident light pattern so explicitly as to delineate irradiance isopleths. |
|
| The UVA and SUV radiometers measure the total global solar irradiance away from any shade. |
|
| Depletion of the Earth's ozone layer is considered responsible for an increase in the solar ultraviolet irradiance reaching the surface. |
|
| From these values the integrated irradiance values are obtained for the desired time interval. |
|
| This irradiance and the radiance in the opposite direction were then inserted into equation to calculate the ideal reflectance. |
|
| We computed the ratio of direct to total horizontal irradiance as a function of SZA and column ozone amount. |
|
| That is why the use of the display unit and communications with the inverter are not possible at night or when there is too little irradiance. |
|
| This paper examines the dependence of whole leaf hydraulic conductance to liquid water on irradiance when measured with a high pressure flowmeter. |
|
| This model was developed to provide UV irradiance calculations and UVI estimations with high accuracy for different atmospheric, temporal and geographical conditions. |
|
| The model was more sensitive to leaf orientation than leaf optical properties, seabed reflectance, or the average cosine of downwelling irradiance. |
|
| The laboratory has developed new facilities for the calibration of spectral irradiance lamps and spectral transmittance measurements. |
|
| Spectral irradiance and spectral radiance calibrations are also available on user-supplied lamps over the same wavelength range. |
|
| The TIM would have used four radiometers designed to measure the solar irradiance to an accuracy of 0.01 percent. |
|
| During the night or at times of insufficient irradiance the LC display is off. |
|
|
|
| The Auto Test can be activated only if there is sufficient irradiance and the inverter is connected to the mains and is in feed mode. |
|
| Spectral radiance measurements proved better than spectral irradiance, for which agreement was worse than that reported in the 1992 comparison. |
|
| The NMi VSL is developing a new facility for spectral irradiance which will be completed in two years. |
|
| A fuse failure is not displayed if the inverter is switched off or in the event of inadequate irradiance. |
|
| Dr Lee mentioned that the KRISS is progressing with the development of spectral irradiance scales based on a high-temperature black body. |
|
| At low growth irradiance, light was the most important determinant of acclimation, while the effect of low nutrient supply was of only marginal importance. |
|
| First, a technical point, Lux is a measure of illuminance, or luminous fLux per unit area, and so the corresponding quantity would be irradiance, or Watts per square meter. |
|
| Direct irradiance was attenuated as described by Beer's law, with the optical path length increasing approximately as the secant of the solar zenith angle. |
|
| This irradiance allowed growth without photoinhibition or photo-oxidation and this is important for effective comparisons of antioxidant activities. |
|
| Consequently, daily variations in irradiance may slow rates of competitive exclusion or reverse the identity of the superior competitor but not allow stable coexistence. |
|
| Mr Nettleton questioned the inclusion of the spectral irradiance comparison data, with particular reference to the NPL results which should not have been included in the final report. |
|
| Measuring and regulation system, Solar Eye, for uninterrupted irradiance. |
|
| If MaxConnect plus is no longer in operation at the time of the ampere hours comparison, the comparison is carried out on the next day with the Ah values of the previous day as soon as the irradiance is sufficient. |
|
| These standards are 200 Watt quartz-halogen lamps, specially selected, aged and calibrated at a fixed dc current and with the spectral irradiance defined at a working distance of 43 cm. |
|
| The instrument has two inputs, A and B, and automatically recognises the probes connected, whether they be illuminance, irradiance, luminance or temperature probes, and can display the difference between the two inputs. |
|
| Both orientations will suffer lower irradiance around solar noon due to an increased incident angle when the sun is from south. |
|
| Radiometry, photometry: Work has begun on the realization of a standard of near-infrared spectral irradiance using the high-temperature sodium heatpipe black body. |
|
| Pre-sampled irradiance and irradiance gradients for non-distant, mid-range lighting will be discussed along with methods for using PRT with dynamic, deformable geometry. |
|
| The authors tested 17 light units from 16 salons with a wide range of bulbs, wattage and irradiance emitted by each device for their research letter. |
|
| Since 1978, solar irradiance has been measured by satellites. |

|
| The analysis shows the strengths of the associations of microinverter temperature with ambient temperature, PV module temperature, irradiance and AC power of the PV systems. |

| The Atonometrics Irradiance Measurement System transforms a cell or module planned for use at a project site into a PV reference device to measure insolation. |
