Meteorological information has obvious spatial-temporal characteristics. Although it is meaningful to employ a geographic information system (GIS) to visualize and analyze the meteorological information for better identification and forecasting of meteorological weather so as to reduce the meteorological disaster loss, modeling meteorological information based on a GIS is still difficult becaus...

Better quantification of isotope ratios of atmosphere-ecosystem exchange of CO2 could substantially improve our ability to probe underlying physiological and ecological mechanisms controlling ecosystem carbon exchange, but the ability to make long-term continuous measurements of isotope ratios of exchange fluxes has been limited by measurement difficulties. In particular, direct eddy covariance...

Due to complicated interactions in the atmospheric environment, quantifying the influence of individual meteorological factors on local PM2.5 concentration remains challenging. The Beijing-Tianjin-Hebei (short for Jing-Jin-Ji) region is infamous for its serious air pollution. To improve regional air quality, characteristics and meteorological driving forces for PM2.5 concentration should be bet...

OBJECTIVES This study investigated the socio-demographic characteristics and medical causes of death among meteorological disaster casualties and compared them with deaths from all causes. METHODS Based on the death data provided by the National Statistical Office from 2000 to 2011, the authors analyzed the gender, age, and region of 709 casualties whose external causes were recorded as natur...

Weather radar data quality control is extremely important for meteorological and hydrological applications. For weather radars, scatterers in the atmosphere are not only meteorological particles like cloud, rain drops, snowflakes, and hails, but also non-meteorological particles such as chaff, insects, and birds. For radar meteorologists it is a major issue and challenge to design numerical sch...

This paper discusses the latest results from ongoing work concerning the calibration and evaluation of temperature and ozone from the Microwave Limb Sounder (MLS) instrument aboard NASA’s Upper Atmosphere Research Satellite (UARS). The method involves using the data assimilation statistics from the UK Met. Office Numerical Weather Prediction (NWP) System. This work provides the template for fut...

Earth observation from space allows us to better understand natural phenomenas such as marine currents, to prevent or follow natural disasters, to follow climate evolution and many other things. To achieve that, there are a great number of artificial satellites orbiting Earth, equipped with highresolution optical instruments and communicating with a network of ground stations. A satellite is sa...

Fourteen pilots flew a synthetic vision system (SVS) display, through a terrain and traffic-rich environment in a high fidelity flight simulator. Traffic information was hosted on the SVS display. In a 2x2 factorial design, the SVS display hosted a highway-in-the-sky in half the conditions, and hosted an instrument panel overlay in the other half. We examined the effects of the resulting clutte...

The Multi-angle Imaging SpectroRadiometer (MISR) instrument aboard the Terra spacecraft is pioneering a new paradigm in remote sensing of the Earth's environment and climate system. MISR acquires radiometrically and geometrically calibrated imagery at moderately high spatial resolution (275 m) over a widelyspaced array of along-tracking viewing angles (up to 70" from local vertical). New algori...
