This paper describes two methods for computing direct covariance fluxes from anemometers mounted on moving platforms at sea. These methods involve the use of either a strapped-down or gyro-stabilized system that are used to compute terms that correct for the 1) instantaneous tilt of the anemometer due to the pitch, roll, and heading variations of the platform; 2) angular velocities at the anemo...
Background and aims Thermal stress is one of the important issues of physical stress in workplaces. Bakery workers that are one of widely population that under occupation heat stress. In this study, heat stress indexes consist of HSI and WBGT in worker positions in total of 88 bakeries in Hamadan city was assessed. Methods In this study 88 bakery workplace was considered. Measuring of ...
The parametrizations of meteorological variables provided by the Monin–Obukhov similarity theory (MOST) is major importance for pollutant dispersion assessment. However, complex flow pattern that characterizes urban areas limits applicability MOST. In this work, performance different existing standard deviation vertical wind velocity were tested in city Rome. Results compared with experimental ...
