Description
A dataset containing a sequence of 72 spectra measured with an
Ocean Optics Maya2000 Pro spectrometer and a Bentham DH-7-SM cosine
diffuser. Values measured on 30 April 2014, in the late morning, under
clear sky conditions. The whole sequence was measured in 39 seconds in a
sunfleck under young silver birch trees. Place: University of Helsinki,
Viikki Campus, Finland. Coordinates: 60.227162 N, 25.019429 E. 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).
