Datasets containing the wavelengths at a 0.5 nm to 1.0 nm interval and tabulated values of measured spectral irradiance for the sun.
A data frame with 1425 rows (250 nm to 900 nm, variable step) and 3 variables.
The variables are as follows:
w.length numeric (nm)
s.e.irrad numeric (W m-2 nm-1)
Instrument used: Maya2000Pro scanning double monochromator spectroradiometer with a Bentham cosine corrected input optics. Recently calibrated at STUK. Date and time: 31 May 2013, 11:23 EEST. Place: University of Helsinki, Viikki Campus, Finland. Coordinates: 60.226183 N, 25.018302 E. Measurements done by Pedro J. Aphalo. Calibration and corrections done with package MayaCalc using bracketing and noise reduction (with filter measurement) and method "sun". Algorithm and calibration data by Lasse Ylianttila (STUK, Helsinki, Finland).
