Abstract In this research, optical humidity sensors based on etched-optical fibers coated with graphene Oxide (GO), silica gel (Sg) and a silica gel modified with GO (GSg) was studied. Their humidity sensing behavior was investigated by variation of relative differentiation of attenuation (RDA) in the presence of relative humidity (RH). As the results showed, etched fibers coated with Sg and GSg are highly capable of humidity sensing. However, a Sg- coated sample is not useful as humidity sensor related to sample coated by GSg because its RDA lacks a one-to-one correspondence with RH. As it was also found, the sensitivity of a GSg-coated sample is higher when the RH is below 40% and its repeatability is considerable.

Abstract. Accurate measurements of temperature and water vapor in the upper-air are of great interest in relation to weather prediction and climate change. Those measurements are mostly conducted using radiosondes equipped with a variety of sensors that are flown by a balloon up to lower stratosphere. Reference Upper Air Network (GRUAN) has identified water vapor pressure as one of the most important measurands and has set an accuracy requirement of 2 % in terms of the mixing ratio. In order to achieve the requirement, many errors in the humidity measurement such as a temperature dependency in sensing characteristics including measurement values and response time need to be corrected because humidity sensors of radiosondes pass through low-pressure (1 kPa) and low-temperature (−80 ∘C) environments in the upper-air. In this paper, the humidity sensing characteristics of Jinyang radiosonde sensors in relation to temperature dependencies were evaluated at low temperature using a newly developed ultralow-temperature humidity chamber. The sensitivity characteristic curve of the radiosonde sensors was evaluated down to −80 ∘C, and the calibration curves of the humidity sensor and the temperature sensor were obtained. The response time of humidity sensor slowly increased from 52 to 116 s at the temperature from 20 to −40 ∘C, respectively, and then rapidly increased to almost one hour at −80 ∘C. Those results will help to improve the reliability of the upper-air observation data.
