Coastal atmospheric conditions widely vary from those over inland due to the land-sea interface, temperature contrast and the consequent development of local circulations. In this study a field meteorological experiment was conducted to measure vertical structure of boundary layer during the period 25-29 June, 2007 at three locations Seabee base, Harrison and Wiggins sites in the Mississippi co...

Collecting and analyzing data lies at the basis of the scientific method: findings about nature usher new ideas, and experimental results support or refute theories. All this is not very prevalent in computer science, possibly due to the fact that computer systems are man made, and not perceived as a natural phenomenon. But computer systems and their interactions with their users are actually c...

Mesoscale (10 2000 km) meteorological data assimilation and prediction are challenging due to the sparseness of observations, especially in the upper-air atmosphere. In the past 15 years, a number of instruments, e.g. wind profilers, commercial aircraft reports, satellite measurements, and others, have been developed to enhance the upper-air observations. Despite these advances, the present sys...

The Meteorological Assimilation Data Ingest System (MADIS) is a data assimilation and distribution system developed by the National Oceanic and Atmospheric (NOAA) Office of Atmospheric Research Earth System Research Laboratory/Global Systems Division (ESRL/GSD) to perform the functions of data ingest, data integration, processing for QC, observation network monitoring, and data distribution for...

In 2006, Chongqing suffered from agriculture drought that happens once a hundred years, and forest fire was caused at the same time. In order to provide accurate and timely data to Chongqing Government for their decision making, we took MODIS (Moderate Resolution Imaging Spectroradiometer) as remote sensing data resource, and meteorological observations as another important data. To simplify th...

The formation and break-up of ice on the Great Lakes as observed by regular ice reconnaissance flights conducted by the Meteorological Service of Canada is discussed in terms of the meteorological parameters involved. Ice cover on the individual lakes over the past four years is correlated with the winter temperature regime and an index of the heat stored in each lake using the concept of cumul...

The Chinese observed land-surface air temperature data set includes measurements from 731 meteorological stations from 1951 to the present, as collected and processed by the National Meteorological Center of the China Meteorological Administration (1, 2). Because some stations were removed, the actual total number of stations in operation today is 671, distributed among 31 provinces and municip...

This study investigates the improvement of ozone (O3) simulations in the Mexico City basin using a threedimensional variational (3DVAR) data assimilation system in meteorological simulations during the MCMA-2003 field measurement campaign. Meteorological simulations from the NCAR/Penn State mesoscale model (MM5) are used to drive photochemical simulations with the Comprehensive Air Quality Mode...
