This study aims to investigate some characteristics of the moist processes of the Madden-Julian oscillation (MJO), by making use of joint HDO (or δD) and H2O vapor measurements. The MJO is the main intraseasonal mode of the tropical climate but is hard to properly simulate in global atmospheric models. The joint use of δD-H2O diagnostics yields additional information compared to sole humidity m...

Reviewer #1 This study reports on measurements using single particle cavity ring-down spectroscopy to derive refractive index values as a function of both wavelength (400 – 650 nm) and relative humidity for numerous inorganic solutes of atmospheric relevance. The topic of this paper is of relevance to this journal and it is of important to the research community as information related to refrac...

atmospheric visibility is a key factor in everyday life mainly in aviation, industry and surface traffic. it has been defined as the greatest distance at which an observer can just see a black object viewed against the horizon sky which is known as the visual range. furthermore, light extinction which is mostly due to absorption and scattering effects of aerosols in the atmosphere, can be calcu...

Sound propagates as a longitudinal wave disturbance in compressible media such as air. If the properties of the medium vary with spatial position or if the medium itself is in motion, the sound propagation will be affected. Therefore, for the Birdstrike project it is important to understand the potential effects of atmospheric temperature, wind, relative humidity, and other effects that will be...

Iteration method for simultaneous estimation of vertical profiles of air temperature and water vapor with the high spectral resolution of sounder of AQUA/AIRS data is proposed. Through a sensitivity analysis based on the proposed method for the several atmospheric models simulated by MODTRAN, it is found that the proposed method is superior to the conventional method by 41.4% for air temperatur...

The fluorescence detection of ultra high energy cosmic rays requires a detailed knowledge of the fluorescence light emission from nitrogen molecules over a wide range of atmospheric parameters, corresponding to altitudes typical of the cosmic ray shower development in the atmosphere. We have made a precise measurement of the fluorescence light spectrum excited by MeV electrons in air. The relat...

This paper introduces a multi-parameter measurement system, which is used for recording the temperature and humidity, atmospheric pressure, rotation speed and acceleration, etc. The system uses a 32-bit RISC microprocessor of STM32F103ZET6 based on the core of ARM Coretex-M3 as master chip. Meanwhile, it writes the data recorded to NAND FLASH. After it is over, it copies the data to host-comput...
