Abstract. As the near-surface atmosphere over Antarctic Plateau is cold and pristine, its physico-chemical conditions resemble to a certain extent those of high troposphere where cirrus clouds form. In this paper, we carry out an observational analysis two shallow fog forming in situ at temperatures – that is, lower than 235 K Dome C, inner Plateau. The combination lidar profiles with temperatu...

The 2D structure of MXenes attracts wide research attention toward an application these materials in gas sensors. These structures are extremely sensitive to minor variations their composition, which employed for tuning functional properties. Here, we consider the partially substituted composition TixV2-xC, where x = 0.2, via quantum chemical calculations, and test chemiresistive characteristic...

We present initial results from testing a new remote sensing system called the Active Temperature, Ozone and Moisture Microwave Spectrometer (ATOMMS). ATOMMS is designed as a satellite-to-satellite occultation system for monitoring climate. We are developing the prototype instrument for an aircraft to aircraft occultation demonstration. Here we focus on field testing of the ATOMMS instrument, i...

Abstract The effect of thermal radiation could be the biggest issue in enclosure calibration. Reducing it by taking accurate measurements can improve calibration uncertainty or measurement capability (CMC). However, there is still less information related to procedure that taken from references such as DKD-R 5-7: Calibration Climatic Chambers, 5-8: Hygrometers for Direct Measurement Relative Hu...

A global, 10-yr (February 1997–April 2006), 2-hourly dataset of atmospheric precipitable water (PW) was produced from ground-based global positioning system (GPS) measurements of zenith tropospheric delay (ZTD) at approximately 350 International Global Navigation Satellite Systems (GNSS) Service (IGS) ground stations. A total of 130 pairs of radiosonde and GPS stations are found within a 50-km ...

EPA is promulgating a significant new use rule (SNUR) under the Toxic Substances Control Act (TSCA) for elemental mercury use in barometers, manometers, hygrometers, and psychrometers. This action will require persons who intend to manufacture (including import) or process elemental mercury for an activity that is designated as a significant new use by this final rule to notify EPA at least 90 ...

1. INTRODUCTION The Met Office UK has been progressing towards an automated upper air network for several years. In 2002, the number of radiosonde stations reporting on a regular basis has been reduced from 8 to 6, but upper air observations are now augmented by the introduction of operational observations from 4 boundary layer wind profilers operating near 1 GHz and the MST radar, Aberystwyth,...

The GCOS (Global Climate Observing System) Reference Upper-Air Network (GRUAN) data processing for the Vaisala RS92 radiosonde was developed to meet the criteria for reference measurements. These criteria stipulate the collection of metadata, the use of well-documented correction algorithms, and estimates of the measurement uncertainty. An important and novel aspect of the GRUAN processing is t...
