Statement: The pyranometer raw data values appear to be 'clipping' at a maximum value of 7999 in these data. This issue is being investigated. The Pyrgeometer temperature sensor (used for sky signal correction) suffered a cable fault between 14:37 UT on 05-Jul-2016 [D187] (1:37am on 6-Jul local) and 02:22 UT on 23-Nov-2016 [D328] The Pyranometer sensor temperatures were substituted for the incorrect Pyrgeometer values during this interval. 2016 The 2016 data includes processed L1 data. 2017 The 2017 data includes raw Campbell logger data, processed L1 data and 5 day summary plots. Note that the pyrgeometer temperature channel in these raw data are not correct. Suspected water ingress in the sensor. The pyrgeometer temperatures were offset (high) from 20:25UT on 17-Jun-17 [D168] and remain offset (by a varying amount) to this day. I have implemented a new correction to check and replace pyrgeometer temperatures with the pyranometer temperature values if the difference is greater than 0.1C. The scaled pyrgeometer irradiance is dependent on Temp^4. Data clipping of the pyranometer channel (Campbell FP2 - IEEE data format) was corrected from 23-May-2017

Notes

Purpose
These sensors provide All-Sky hemispheric (180 degrees) radiation measurements to determine the relationship between incoming short-wave and outgoing long-wave radiation (the 'Energy Balance').
