Abstract: A low-cost (under $12,000), fully automated, relative humidity calibration chamber capable of testing up to six probes simultaneously over a range of humidifies from 5% to approximately 95% is designed, constructed, and ...

Abstract: A major challenge in meteorology is determining the manner and scale at which the land surface interacts with the atmosphere. A majority of field programs, designed to address this issue, have been limited in space and ...

Abstract: This work describes in situ moisture sensor comparisons that were performed in conjunction with the first Water Vapor Intensive Observation Period (IOP) conducted at the Atmospheric Radiation Measurement (ARM) Program ...

Abstract: o better understand the physical processes of the stable boundary layer and to quantify ?submeso motions? in moderately complex terrain, exploratory case-study analyses were performed using observational field data ...

Abstract: Multiplate radiation shield errors are examined using the following techniques: 1) ray tracing analysis, 2) wind tunnel experiments, 3) numerical flow simulations, and 4) field testing. The authors? objectives are to develop ...

Abstract: AbstractThe severe storms research community lacks reliable, aboveground, thermodynamic observations (e.g., temperature, humidity, and pressure) in convective storms. These missing observations are crucial to understanding ...

Abstract: umerical weather prediction models often perform poorly for weakly forced, highly variable winds in nocturnal stable boundary layers (SBLs). When used as input to air-quality and dispersion models, these wind errors can ...

Abstract: revalent methods for making high-accuracy tower-based measurements of the CO2 mixing ratio, notably nondispersive infrared spectroscopy (NDIR), require frequent system calibration and sample drying. Wavelength-scanned ...

Abstract: nthropogenic emissions from urban areas represent 70% of the fossil fuel carbon emitted globally according to carbon emission inventories. The authors present here the first operational system able to monitor in near?real ...
