2BMSGlobal 90-North LI-20009/25/202009:07:0012/15/202119:31:00DATA CORRECTED on 12/17/2021: Irradiances were increased by 0.675% due to revised BORCAL report for all BMS shortwave radiometers calibrated in 2020 and 2021.
3BMSPY1726Global 90-North LI-20007/11/200613:34:0007/14/200613:24:00The PY1726 instrument which was just calibrated in BORCAL 2006-02, was reading about 1.27 times too high. The calibration history shows a continous decline in response from 15 ÁV/W/m^2 in 1998 to 9.7 for 2006. There may be a problem with the instrument, so it was removed and replaced temporarily with PY1724. Another instrument will be calibrated in BORCAL 2006-04 which will serve as the replacement.
