Improved time constant of a newly released air temperature sensor and its implications
Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 771, July 2025 Part B.We set out laboratory response‐time evaluations for a recently released platinum resistance meteorological air temperature sensor from Campbell Scientific. The new sensor fully meets World Meteorological Organization and National Oceanic and Atmospheric Administration specifications for sub‐20 s 63% response time, even at airflow rates as low as 0.2 m ...
