For our observationally based method we rely on a geostatistical analysis of ground observations of PM2.5 concentrations because of the relatively large number of monitoring stations providing accurate measurements across the U.S. By combining methods like LUR and BME we can create a model that is numerically efficient, applicable and interpretable over a large domain size.
A long-term continuous series (1957 1992) of ground-based observations of ULF emissions in the frequency range of 0.2 5.0 Hz (Pc1) was investigated.
The particles follow a power-law size distribution with the power -3 that is close to the one obtained for comet dust in situ, at studies of the Stardust returned samples, and the results of ground-based observations of comets.
An analysis of ground-based observations of solar irradiance was recently published in this journal, reporting an apparent increase of solar irradiance on the ground of the order of 1% between solar minima and maxima [ 1].
As a result the movie feels familiar rather than revelatory — a collection of ideas about the experience of Muslim immigrant women rather than a series of observations grounded in the experience of a particular woman.
That let them bring in two other kinds of observations: ground-based telescopic observations of the infinitesimal color changes of the star induced by the planet's gravitational tugging and Kepler measurements of "starquakes" that reveal more about the nature of the star.
In order to constrain the POES observations, Clilverd et al. ([2010]) have demonstrated the potential of using ground-based observations of changes in ionospheric D-layer ionisation (VLF, very low frequency radio propagation) to establish near-real-time electron precipitation fluxes.
She spearheaded Rosetta's efforts to involve amateur astronomers through social media and recognize the value of their ground-level observations of the spacecraft's path toward deep space.
The novel approach switches between equilibrium and non-equilibrium conditions based on the meta-stable parameter on the grounds of thermodynamics and experimental observations.
In this study, temporal stability analysis and spatial sampling techniques are used to investigate the representativeness of ground observations at satellite scale soil moisture in a semi-arid watershed for a long study period (March 1 , 2002 to September 13 , 2005
