EUMETNET Workshop on AI for Weather and Climate
The EUMETNET Workshop on AI for Weather and Climate took place at the Royal Meteorological Institute in Brussels - my last opportunity to travel abroad in 2020. I presented our work on data-driven QC and probabilistic plausibility, and briefly mentioned other machine learning activities that are happening in the measurements and data department at MeteoSwiss.
Paperboy
Our paper on "Detecting temperature induced spurious precipitation in a weighing rain gauge" has been published in Meteorologische Zeitschrift, Vol. 28, No. 3.
I have contributed to the QC part of "Homogeneity assessment of phenological records from the Swiss Phenology Network", which has been published in the International Journal on Biometeorology, Vol. 64, Issue 1.
EUMETNET STAC WG on Automated Quality Control
I'm a member of the newly founded EUMETNET Scientific and Technical Advisory Committee Working Group on Automated Quality Control. At our first meeting in Exeter, the members presented the data processing and quality control methodologies of their respective met services. I gave a talk on some of the aspects of the MeteoSwiss data processing pipeline, with a detailed introduction to probabilistic plausibility.

Fan SDR Hacking for the Intel S1200V3RP Motherboard [updated]
After a discussion with Andrew Su, this post has been updated to include information on how to select the temperature sensor that controls the fan speed.
I run a home server built around the Intel S1200V3RP motherboard. To minimize noise levels, it is housed inside a Fractal Design Define Mini case, driven by three Scythe Slip Stream 120 PWM case fans and a Noctua NH-U12S CPU fan.
Contrary to typical desktop motherboards, the BIOS of this server board doesn't provide functionality to set a temperature vs. fan speed curve. Intel expects its customers to house the board inside an approved chassis, and provides IPMI sensor data records (SDRs) with pre-defined curves for those chassis. For "other" chassis, Intel also provides three generic SDRs called slow, medium and fast ramp. Here are the steps to choose which temperature sensor controls the fans, and how to modify the fan speed and temperature points of the "slow ramp" curve.
