OOI southern Ocean mooring, deployments 3 and 4

Hello,
In a manuscript in preparation, we would like to reference the finding from the following report

https://datareview.marine.rutgers.edu/instruments/view/GS01SUMO-SBD12-06-METBKA000#annotations

that during the third deployment of OOI mooring in the South Pacific Ocean, an offset of 5 W/m2 has been reported between the two sets of downward longwave radiation (DLW); how can we properly reference this finding?

Also, a comparison of the DLW radiation from this mooring with ERA5 showed that for the time period Jan 2016 - Nov 2018 the difference between the monthly mean DLW radiation estimate from ERA5 and the mooring observations is relatively constant and equals -17.2 Wm-2. After Nov 2018 OOI DLW observations show a sudden jump relative to the previous period. Such a jump is not evident in the reanalysis data and we were unable to find information about the potential offset of the observations during this time period. We would very much appreciate it if you could provide any information on this matter.

Thank you very much,
best regards,

Ivana Cerovecki
