NCAVEO: Delta-T Devices Ltd BF2 sunshine sensor data

A Delta-T BF2 Sunshine Sensor was used to measure the total and diffuse sky irradiance every minute from 10:30 to 13:00 hours on the 17th June 2006, as part of the Network for Calibration and Validation of EO data 2006 Field Campaign. 150 readings were produced in total. The direct energy of the sun on the instrument is calculated from the differences between the total energy and diffuse component recorded simultaneously.
