The potential of condensation trails (contrails) from jet aircraft to affect regional-scale surface temperatures has been debated for years, but was difficult to verify until an opportunity arose as a result of the three-day grounding of all commercial aircraft in the United States in the aftermath of the terrorist attacks on 11 September 2001. Here we show that there was an anomalous increase ...

BACKGROUND AND PURPOSE Many studies have evaluated the association between weather and stroke, with variable conclusions. Herein we determined the relationships between daily meteorological parameters and acute stroke incidence in South Korea. METHODS Patients with acute stroke (2,894) were identified by standard sampling of a nationwide insurance claims database from January to December 2011...

BACKGROUND Several studies have identified the association between ambient temperature and mortality; however, several features of temperature behavior and their impacts on health remain unresolved. We obtain daily counts of nonaccidental all-cause mortality data in the elderly (65 + years) and corresponding meteorological data for Melbourne, Australia during 1999 to 2006. We then characterize ...

. introduction most of the warming over the last 50 years has been caused by emissions of carbon dioxide (co2) and other greenhouse gases due to human activities. observed changes in the climate due to increasing greenhouse-gas concentrations have made it essential to investigate these changes. the general circulation model (gcm) is the most current method of investigating climate change studie...

Spatially continuous satellite infrared temperature measurements are essential for understanding the consequences and drivers of change, at local and regional scales, especially in northern and alpine environments dominated by a complex cryosphere where in situ observations are scarce. We describe two methods for producing daily temperature fields using MODIS ―clear-sky‖ day-time Land Surface T...

background: national surveys in india have documented an increasing number of adolescent girls suffering from anemia. efforts to build iron stores in adolescent girls will help them improve their prepregnancy hemoglobin level. to assess the effectiveness of school-based supervised weekly, bi–weekly, and daily regimen of iron folic tablets in the treatment of anemia among adolescent girls. metho...
