Developer notes

Paul McBrien

I write about the apps I'm building, the tradeoffs behind them, and the parts of the stack that were either surprisingly hard or pleasantly boring.

About

I'm Paul, a developer working across web products, mobile apps, and booking experiences. This site is less portfolio pitch and more notebook: implementation notes, product decisions, dead ends, and the occasional case study when something is worth writing down.

A theoretical semi-empirical model for precise air temperature metrology

Paul McBrien · 13 April 2021

My work, “A theoretical semi-empirical model for precise air temperature metrology,” is listed as reference [7] in the final report of the EURAMET interlaboratory comparison of air thermometer calibration 2023 study. The project brought together national metrology institutes and partner laboratories across Europe, including the UK’s NPL, Germany’s PTB, Ireland’s NSAI National Metrology Laboratory, and Italy’s INRiM.

The comparison examined air thermometer calibration from −80 °C to +60 °C, investigating measurement uncertainty and sources of bias to inform best practice in precision thermometry.
