The models were evaluated in the hindcast mode with a two-year air quality and meteorological data set using a leave-one-month-out cross validation method, and in the forecast mode with a one-year air quality and forecasted weather dataset that included forecasted air trajectories.
The current iOS app, which has been in the works for more than a year, includes a throttle lever for ascending/descending, and a tilt to steer function — which manipulates a small fin on the rear of the module to shift the plane's in-air trajectory.
Monitoring systems may be improved by targeting periods of risk indicated by air-trajectory analysis, knowledge of likely sources, the effect of weather on the biology of spore release and the density of susceptible crops, which can be indicated by remote sensing.
Tom Ewing Jamie Woon Night Air His trajectory from a musical family to the Brit School to the BBC Sound of 2011 poll is crushingly predictable, but this brilliant single from Jamie Woon isn't.
Once these are determined, the indoor air temperature trajectory can be calculated with (1).
Air mass trajectory models demonstrate that air masses that passed over the Grímsvötn eruption site overnight on 21 22 May (Figure 1a) then travelled across the northern part of the UK and onwards to mainland Europe, particularly Scandinavia and Germany.
The forward air mass trajectory calculated by the NOAA's HYSPLIT model is depicted for the radioCs activity concentration peaks, suggesting that the plume from the FDNPP site passed over the Tsukuba region.
In order to assess the role of ET in the hydrologic cycle, we developed an isotopic water vapor transport model wherein we manipulated ET parameters along a specified air mass trajectory.
The majority of the rainfall samples had a Cl− concentration of 1.5 2.5 mg L−1, and the excess of Na+ over Cl−, combined with a strong excess of non-marine SO2−4 and the overall precipitation chemistry, indicates that some solutes were contributed from terrestrial sources during the air mass trajectory over land.
